The Many Faces of Resource Guarding

One of my AutumnGold instructors recently completed a set of in-home lessons with a couple and their young Vizsla. The dog, Sadie, had completed our puppy class last summer and her owners were interested in working on in-home manners. One of the behaviors that Amanda, the instructor, included was target training “go to your mat and down/stay”. We use several approaches to teach this at AutumnGold, one of which employs a remote treat-delivery device such as a Manners Minder or Pet Tudor (see “Manners Minder and Me” for details).

TEACHING ALLY “TABLE’ USING A MANNERS MINDER

The owners were interested a remote trainer, so Amanda borrowed our device so that they could try it for a few weeks. Sadie responded beautifully and rapidly, but unfortunately, just as rapidly developed another behavior – resource guarding.  She learned to stay on her bed and enjoyed the random delivery of treats, but when her owners approached, Sadie began to freeze over the Manners Minder, growling if they came too close.

Oops.

Prior to the start of the lessons, Sadie’s owners had not identified resource guarding as a problem. However, during their first meeting, Amanda noticed that Sadie stiffened slightly after she gave her a stuffed Kong. This was quickly diffused by teaching Sadie to “make a trade” and Amanda saw no other signs during that lesson. When questioned further, the owners did say that they sometimes saw similar body postures when Sadie was approached while eating. Amanda talked with them about the body language signs of resource guarding and cautioned them to watch for similar signs (or an escalation) after introducing the Manners Minder to Sadie. And sure enough…..there it was.

Amanda is a skilled trainer and quickly intervened with a behavior modification program to prevent and treat Sadie’s resource guarding. However, what Amanda and I found interesting about this episode was that the owners had not previously mentioned a specific problem with resource guarding to Amanda. Granted this is a young dog, the initial guarding behavior was subtle and there was no bite history. Still, we wondered, was this because the owners had not been consciously aware of Sadie’s stiffening body posture previously or that they had noticed it but were not sure that it implied a problem?

Identifying resource guarding: Most dog owners think of resource guarding as overt aggression (and certainly that is how it manifests at its most severe). Additionally, rather than being viewed as a general pattern of behavior, owners typically report the specific items that are guarded;  i.e. “she is not good around her food bowl” or “he does not like being approached when he is chewing on his favorite bone“. However, there can be several more nuanced signs that suggest a dog may be highly invested in toys, a food bowl or a resting spot. These include becoming “still”  (stiffening/freezing), abruptly changing body position to block access, hiding or running away, or rapidly ingesting food (or a stolen item) when approached. It is these more subtle signs that may be unnoticed or misconstrued, and that in some cases might be precursors of later aggression.

NOT THE ONLY FACE OF RESOURCE GUARDING

Do we notice other signs? The question of how much attention dog owners generally pay to the other faces of resource guarding was recently examined by a team of researchers at the University of Guelph in Canada.

The Study: They asked a group of almost 1500 dog owners to view short video clips that portrayed dogs who were approached near their food bowl or when chewing on a rawhide chew toy. For each clip, participants were asked to classify the behavior that they viewed into one of these five categories: Aggression (snaps, bites or attempts to bite); Threat (freezing, stiff or tense body posture, hard stare or growl); Avoidance (moves head away and actively avoids removal of item, runs away with item); Rapid Ingestion (increases speed of ingestion, gulps at food rapidly); or No Resource Guarding (relaxed, loose, wiggly body posture).  Each of the behavior categories had been previously validated by a team of behavior experts.

Results: Several interesting findings were reported:

  • Perhaps not surprisingly, the participants, all dog owners, were highly capable of correctly identifying overt aggressive behavior associated with resource guarding. They were similarly adept at knowing when a dog was relaxed and friendly and showed no signs of guarding behavior.
  • Conversely, owners were less likely to correctly identify the more subtle signs of resource guarding such as avoidance, rapid ingestion and even threatening behaviors (freezing and staring).
  • When the three types of non-aggressive behaviors were compared, owners were better able to recognize threatening behavior than they were to recognize avoidance or rapid ingestion. The authors speculated that owners are more sensitive to behaviors that they think of as being potentially threatening than those that appear to be benign, such as running away or eating rapidly.

Take Away for Dog Folks

At AutumnGold, our potential clients complete a four-page behavior profile form for their dog prior to being admitted into class. The form includes questions about their dog’s behavior during mealtime, around their food bowl, with toys and when resting. It is not unusual to receive profiles that report  dogs who run away or avoid interactions with high-value toys, or who becoming still/stiff when approached while eating or resting in a favorite spot. We always respond to these applications with a phone consultation. In some cases the avoidance behavior is simply a (learned) game of “catch me if you can” or the avoidance that the owner reports is just an untrained dog who has not been taught to come when called. However, is some cases, we identify these behaviors as a form of resource guarding and are able to intervene and provide early guidance.

The results of this research suggest that many owners perceive the more subtle forms of resource guarding as being harmless or inconsequential, or they do not notice them at all. For professional trainers, this information encourages us to better understand the perspectives of clients and to proactively teach owners to identify and understand some of the more subtle body language signs in their dogs before they develop into aggressive responses.

As for Sadie, she learned to go to her mat reliably using clicker training and polished up her “sit for greeting” behavior to control her very exuberant personality with visitors. Amanda also provided Sadie’s people with a set of canine body posture handouts and discussed the implications of stillness, freezing and avoidance behaviors in dogs. Sadie’s owners were highly interested in this information and rapidly became talented “dog behavior sleuths” with their girl, recognizing situations in which Sadie felt compelled to guard and managing her life to avoid or prevent those settings. Her owners also regularly practice “make a trade” and “give” with Sadie for all types of items (not just those that are high-value) so that she learns to happily give up toys and other items without becoming stressed or defensive.

All-in-all a happy outcome, with everyone benefiting from this type of research and its application to evidence-based training!

Just Show Me A Sign

Like many dog trainers, I use both verbal and gestural (hand) signals as cues with my dogs. With our students at AutumnGold, we introduce both verbal and physical cues at the same time, but generally emphasize verbal signals because this is what most pet owners prefer to use with their dogs.

AG Down Stay

AUTUMNGOLD STUDENTS USE GESTURES AND VERBAL CUES WHILE PRACTICING DOWN STAYS

All of our classes include instructions for fading gestural cues in favor of  verbal cues for owners who wish to use primarily verbal signals. Students are taught to “lead with the verbal cue and follow with the gesture“, thus establishing a classical relationship (verbal signal predicts gesture signal). This connection allows the trainer to gradually fade the hand signal and eventually to rely primarily on the verbal command.

On the other hand (literally), hand signals are a lot of fun to teach and come in handy in a wide variety of exercises. For these, we offer a dedicated “hand signals” class, for students who are interested in teaching their dog distance signals and hand cues for direction or jumping. This is great fun for dogs and their people and is also helpful for students who are interested in competing in dog sports.

Chip Agility Jumping  Chip Down Signal                      CHIPPY SHOWS OFF HIS HAND SIGNALS FOR JUMPING AND DOWN

However, like many dog training practices, the use of verbal versus hand signals with dogs has not been formally studied. Until recently, that is.

Enter Biagio D’Aniello and his team of scientists at the University of Naples (among others) in Italy. I have written about this group’s research on previous occasions. They work with retrievers who are trained for water rescue work and are reporting new information regarding the dog’s communication skills and ability to learn through observation (see “With a Little Help from My Friends” and “Doggie See, Doggie Do“).

This time around, the researchers asked whether dogs who are trained to respond equally to verbal and gestural cues show a preference for one type over the other.

The Study: A group of 25 certified water rescue dogs were enrolled. The group included 10 Golden Retrievers and 15 Labrador Retrievers, composed of 12 males and 13 females. Per training protocols for water rescue, all of the dogs had been trained to respond to both verbal and gestural cues. The dogs were tested in four behaviors; sit, down, stay and come. The study was conducted in three phases. Phase 1: The four basic commands were given using gestures only. Phase 2: Commands were delivered using a verbal cue only. Phase 3: (Here is where things get tricky). Both forms of a command were given, but incongruently (i.e. they conflicted with each other). For example, the verbal command for “sit” was paired with the gesture for “down”, the verbal command for “come” was paired with the gesture for “stay”, etc. The frequencies of correct responses were recorded in the first two phases, and a “preference index” that indicated the percent of correct gestural responses was calculated for the third phase.

Results:

  1. Just a sign, please: When gestures alone were used, all of the dogs responded correctly to all four commands, with the exception of a single error (one dog missed a “down” signal). In contrast, when verbal cues were used, the dogs made a total of 18 errors. The most common mistake was failing to lie down in response to the verbal command “down”. These results suggest that dogs who were trained using both verbal and hand signal cues (and when no attempt was made to emphasize one type of signal over the other), the dogs responded more consistently to gestures than to verbal cues.
  2. Location, location, location: While dogs showed an overall preference for gestures over verbal commands, this preference was not found when the verbal command to “come” was paired with the hand signal “stay” and the owner was located a distance away from the dog. In this case, the majority of dogs (56 %) responded to the verbal command. This difference suggests that although the dogs tended to pay more attention to hand signals than to verbal commands, this preference may be overridden by the preference to stay in close proximity to the owner.
  3. Girls may be more visual: An interesting result of this paper was the sex difference that was found. Female dogs showed a strong preference for responding to hand gesture cues, while males were more likely to respond equally to both types of cue. (Note: Although there is a bit of previous research suggesting that female dogs concentrate more on visual cues than do males, the small numbers in this trial coupled with the method of scoring lead the researchers to interpret this result with caution – in other words, this may be a “statistical hiccup”).

This pilot study suggests that when dogs are trained to both hand signals and verbal commands, they will respond most consistently to hand signals. The study also suggests that context is an important factor, in that having a preference to be close to the trainer may override a preference for gestural signals, leading a dog to choose the signal (verbal or gestural) that leads to proximity.

Take Away for Dog Folks

The finding that dogs (usually) respond better to hand signals than they do to verbal cues is probably not surprising to most trainers. This certainly supports our understanding of dogs as being highly responsive to body language and non-verbal cues. Still, it is always gratifying to find scientific data that supports one’s (previously unsupported) suppositions.

This is Data

Do hand signals have enhanced saliency? However, is it possible that there is more to the differences found in this study than is explained by the dog’s proclivity for reading body language? This paper lead me to think more deeply about these two types of signals; specifically about the type of hand signals that we choose to use.  The majority of hand signals that we use in dog training are far from being  arbitrary signals. Rather they are structured in both form and function to direct the dog’s attention or body to part or all of the targeted behavior. For example, a commonly used hand signal for “down” is  a sweeping motion from the dog’s “nose to his toes”. During training, this gesture easily doubles as both a lure when food is held in the hand and as a vehicle to deliver positive reinforcement when the hand delivers a food treat once the dog attains the down position. A reliable response to the hand signal alone is achieved by gradually removing the lure from the signaling hand and switching to +R from the opposite hand. We are then left with a hand signal that has, well, enhanced saliency for the dog, if you will. A second example is the use of body language and hand signals to inform a dog about the direction to run or jump in agility training. The physical signal itself has inherent meaning to the dog (we all get this). This signal is then enhanced by pairing it with food or an opportunity to tug. Contrast these gesture examples to the variety of verbal cues that we use with dogs (sit, down, come, etc). All of these, of course, are completely arbitrary from the dog’s point of view. We could just as easily use the word “down” to train a down command as the word “pumpkin” or “fluffy butt”. While we do enhance saliency by pairing these terms with reinforcers, they cannot be structured in the same way that gestures can to be naturally obvious (salient) to the dog.

So, in addition to dogs being highly attentive to body language (I think we all agree on that), it also seems that the hand signals that we select function to naturally attract our dog’s attention and direct behavior. The trainer “beefs up” this attraction by pairing the signal with positive reinforcement. Therefore, gestural cues may always have one step up over verbal cues when comparing the two (when the owner is in close proximity). Here is an idea – try training a sit using a down hand signal or teaching an agility dog to jump in the opposite direction from which you are pointing. In addition to this being a bit of a training challenge (more than a bit, I suspect), I would hypothesise that when arbitrary gestural signals are compared with verbal cues, we might see a leveling out of the preferences for gesture versus verbal signals. Just an idea……any researchers biting?

A role for individual preference and reinforcement history? I also pondered what the influence of an individual’s preference might be in this type of testing. All dogs tend to have certain exercises that they enjoy more than others. Some of these exercises may be inherently reinforcing for the dog while others may simply be preferred because they have a strong reinforcement history with the trainer (i.e. the exercise has been practiced and reinforced more frequently). In the case of this study, we might expect that dogs trained for water rescue work would be highly bonded to their owners and would also have a very strong reinforcement history for the “come” command. It would be interesting to explore verbal versus gesture preferences in dogs who are trained for different types of work, who may have different behavior preferences and reinforcement histories. Such a test would be analogous to the study that this same group did with dog’s looking back for help, in which they found some very interesting differences.

In practice: From a practical viewpoint, as a trainer, these results suggest to me that we should be doubly careful when fading hand signals in favor of verbal cues, especially when training a dog’s less preferred behaviors. While this research suggests that dogs are asking us to “just show me a sign”, it also seems that their responses will be influenced by a number of factors, including looking for the cue that tells them what they want to hear!

The Meaning of Click

Hi. My name is Linda and I am a clicker trainer. In the spirit of full disclosure, I admit that I have been using a clicker for many years. My use began with the common gateway secondary reinforcer, the verbal cue (“Yes!”). While that worked well for a while, I eventually found that I needed more. I wanted a marker that was accurate and clear to my dog and something that could provide that immediate “ah ha!” moment in dog training that we all crave.

BABY COOPER HEELS FOR CLICKS

Recently, my husband suggested that perhaps I am too dependent upon my clicker. It is possible that finding them all over the house, in the pockets of my jackets and jeans, in the car, and oh yeah, one in the refrigerator, had something to do with his concern. I emphatically denied this and insisted that I could quit clicker training any time that I wanted to.

He called my bluff and suggested that I try using food alone, no clicker. Admittedly, I did not react well.

PERHAPS I AM A BIT DEPENDENT

Hyperbole aside, why is it that many trainers, myself included, are so completely sold on clicker training? While the short answer is a forehead thumping “Duh…..because it works so well“, a longer exploration into clicker training, plus a bit of science, is needed to fully understand this phenomenon.

Operant learning: There is a large body of  scientific evidence supporting the effectiveness of using consequences to teach new behaviors, a type of associative learning called operant learning or conditioning.  Although the consequences that are used can be either aversive or pleasurable, most trainers focus on pleasurable consequences, or positive reinforcers. For dogs, a universal primary positive reinforcer is food, though verbal praise, petting, and play are also important. (Note: A primary reinforce is a stimulus that is inherently rewarding to the animal, with no need for prior conditioning). Animals learn most efficiently when the targeted behavior is immediately followed by delivery of the positive reinforcer. Even brief delays between the behavior and the reinforcer can slow or prevent learning.

The timing issue: Herein lies the problem. In the practical context of animal training, there are numerous  situations in which it is impossible for a trainer to deliver a primary reinforcer at the exact time that the desired behavior is being offered. Examples with dogs include when teaching retrieving, targeting distant objects, or moving a paw or other body part in a very precise manner. Secondary reinforcers help to solve this problem. These are signals that are clear to the animal, such as a sound or light flash, and which are purposefully paired with a primary reinforcer. For marine mammal trainers, a whistle is used. For dog trainers, it is the click.

clicker-training_gif

Click-Treat: The sound of the clicker is transformed from a neutral (meaningless) stimulus to a conditioned (secondary) stimulus by repeatedly pairing the click sound with the delivery of a food treat (the primary reinforcer). After multiple repetitions of Click-Treat (hereafter CT), in which the click sound reliably precedes and predicts the treat, the click begins to possess the same properties as  the treat itself. Clicker training allows the trainer to precisely target (mark) tiny bits of behavior at the exact moment they are occurring. The click sound becomes analogous to a bridge in time – saying to the dog “That’s it!! That thing that you are doing right this instant is what will earn you the yummy treat that is coming shortly!”

Well, at least that is what we think the click means to our dogs………

The meaning of click: Recently, a team of Australian researchers reviewed clicker training and examined the mechanisms through which clicker training might enhance learning (1). They looked at each of the three functions that dog trainers typically attribute to the click –  a secondary reinforcer,  a marker of behavior, and as a bridging stimulus. Although we typically give equal weight to all three of these functions, the current evidence, collected primarily in laboratory animals and pigeons, is telling us differently:

Secondary reinforcer? As described earlier, once a clicker is “charged” as a secondary reinforcer, it should possess the same reinforcing properties as the primary reinforcer (treat). This means that the click sound alone, without being followed by a treat, is expected to cause an increase in the targeted behavior and help learned behaviors to be resistant to extinction. An unpairing of the connection between secondary and primary reinforce should also lead to a lessening of these effects. All of these outcomes have been tested in rats and pigeons and the evidence overwhelmingly suggests that a conditioned signal (click), when consistently paired with a primary reinforce (treat) does indeed take on the properties of the primary reinforcer. The researchers also provide  evidence (in rats) of a neuropsychological nature – dopamine release has been shown to occur at times that would be expected if a secondary reinforcer was the driving mechanism for learning.

Event marker? Almost all clicker trainers, when asked to explain why clicker training works so well, include some version of “it precisely marks the behavior that I wish to reinforce, at the exact moment that it is happening“.  I agree with this account, given my own practical training experiences. But, of course, belief is not the same as evidence.  What does the current science say about using an auditory signal to mark behavior? As a marker, the signal (click) must draw the animal’s attention to the event. So, if a signal functions to mark behavior, we would expect to see an effect of the signal, though at a lower intensity, when it is not paired with a primary reinforcer. For dogs, this means that hearing the “click” sound, regardless of its pairing with food, should emphasize that moment and thus enhance learning whatever behavior is occurring. Again, though not tested with dogs (yet), this hypothesis has been tested with laboratory animals. The evidence suggests that learning is somewhat enhanced by a marker alone but that the pairing of the marker with a primary reinforcer is decidedly more potent. While “click” may indeed be a marker for behaviors, this function is intricately related to its role as a secondary reinforce rather than marking an event simply by bringing the animal’s attention to it.

Bridging stimulus? The bridging stimulus hypothesis focuses on the “a treat will be coming to you soon” portion of clicker training and applies when the dog is a distance away or there is a temporal (time) delay between the behavior and delivery of the food treat. According to the bridging hypothesis, rather than simply marking the behavior, the signal communicates to the animal that reinforcement will be delayed (but is still promised). A limited number of published studies have examined this function, but the evidence that is available suggests that an auditory signal (such as a click) may bridge the temporal gap between behavior and food. However, all of the studies used a type of training process called “autoshaping” which is a highly controlled and contrived experimental process. Whether or not a click acts as a bridge in the practical and varied setting of dog training remains to be studied.

Take Away for Dog Folks

The bulk of the current evidence coming from other species, primarily lab animals who are tested in highly controlled conditions, tells us that the major way in which clicker training enhances learning is through the click’s function as a secondary reinforcer. As far as event marking and acting as a bridging stimulus, these may be in effect, but if so, they are in a supporting role rather than being the star players. So what might this information mean for we who love to click?

  1. In its role as a secondary reinforcer, the click takes on the pleasurable properties of the primary reinforcer, food treats. Pairing of the click with the treat (charging the clicker) is essential to both establish and maintain these properties.
  2. While clicking without treating will work for a short period of time, repeated uncoupling of the click from the treat will extinguish the connection and the click will stop being effective as it gradually reverts to a neutral stimulus.
  3.  Although most of us refer to the click as “marking” behaviors, the actual marking properties of the click appear to be intricately linked to its function as a secondary reinforcer, rather than having any stand-alone strength in this capacity. Ditto for bridging stimulus.

Bottom line? Given  these three suppositions, if you are a trainer and are in the habit of clicking without treating, you may want to stop doing that (2). The power of the click lies principally in its strength as a secondary (conditioned) reinforce, so maintaining that connection appears to be key.

As for me, this evidence provides further support for the strength of clicker training with dogs. Don’t think I will be going through any 12-step program to reduce my dependency anytime soon.

Manners Minder and Me

In the previous essay, “Doggie See, Doggie Do?”  I discussed research showing that dogs may be capable of learning new tasks simply by observing another dog being trained. I mentioned that when I work with my own dogs, I rotate among them by training each dog to perform a down/stay on the pause tables located on the side of our training floor.

Ally Learns High Five on her Platform

 CHIP AND COOPER WAIT THEIR TURNS TO TRAIN

In our family, Chippy and Cooper are the most recent in a long line of Case dogs who have learned to “wait their turn” on their platform bed. Admittedly, this is not an easy behavior to teach seeing that my dogs love to train and ultimately view their time on the platform as the “down-stays of doom“.

The approach to training this is pretty simple. I first teach a solid down-stay on the platform with no distractions, and then shape time and distance separately using click/treat. Getting a solid down/stay on the platform is the easy part……the difficulty lies in getting that stay to hold while another dog is out on the floor, having all of the fun. Until recently, I accomplished this by returning to the platform frequently with a click/treat for staying, gradually lengthening the time interval between +R. If the dog frequently jumped off of the platform, I would lower my criteria or put the dog in the x-pen and return to the task at another time.

Enter Alice (aka Alice Bo-Balice), our newest family member.

Ally Coop Chip on Table

CHIPPY, COOPER AND ALLY

With Ally, I decided to change things up a bit and use a remote training device for this task. There are several commercial versions of these available, and I used a “Manners Minder” (now called “Treat & Train”). This device was initially created by the late Dr. Sophia Yin and it functions by providing remote +R in the form of small dry or semi-moist treats. Delivery can be controlled either manually with a handheld control or via an automatic and adjustable reinforcement program. A tone precedes treat delivery and is used as a conditioned reinforcer.

Manners Minder

The Questions: I know that I can teach this behavior to Ally using the same +R approach that I have used in the past with our other dogs. However, I wondered whether training a down/stay on a platform might be more efficient using a remote trainer. As I see it, there could be both benefits and potential disadvantages to these devices:

Potential Advantages:

  •  The remote trainer is a large and physically obvious cue that can be paired with the target area (bed) and which becomes a conditioned reinforcer  (i.e. its presence consistently predicts the arrival of a primary reinforcer in the form of  treats).  This is an advantage in that it quickly signaled to Ally that the bed was “the place to be” whenever the Manners Minder was placed there.
Ally and Treat & Train 2

ALLY AND HER MANNERS MINDER

  • Provides +R remotely that is associated with a particular target (bed) and is disassociated from the trainer (me). [Note: I consider this property both an advantage and a disadvantage – see below].
  • Use of a very precise intermittent reinforcement schedule (I used variable intervals, called the “down stay” setting with the device, but there are several available settings)

Potential disadvantages:

  • Dependency on the presence of the device: I suspect that Ally’s down/stay may, at least initially,  break down when I attempt to remove the device and +R her down/stay in its absence.
  • Device malfunction (this happens relatively frequently, when treats get stuck in the mechanism), leading to poor timing and frustration for the dog.
  • Provides +R that is disassociated from the trainer: One of the best things about training dogs, in my view, is that it enhances communication with our dogs and strengthens the bonds that we have with them. Removing the trainer (me) from this equation therefore removes a number of opportunities for positive interaction and bond-building with Ally.

What does the Science say? To date, there are two published studies of the effectiveness of remote training devices for teaching targeted down/stays with dogs. The first of these was conducted by Dr. Sophia Yin and published in 2008 and the second, using a similar device, was conducted by a group of researchers from Budapest, Hungary in 2016 (1,2). Let’s see what they have reported:

Study 1:  This study was conducted in two phases, each using dogs who had a history of problem behaviors at the door (rushing, barking). In the first phase, six dogs were trained by an experienced dog trainer in a laboratory setting to move to a platform bed and offer a down/stay using the Manners Minder. In the second phase, the same training protocol was used with a group of 15 dogs who were trained in their homes by their owner. A control group of 6 dogs received no training at all. Results: All six dogs who were trained in the laboratory setting successfully learned to maintain a down/stay on a bed for a period of 1 minute, when trained using the remote trainer. In phase 2, although the average amount of training time was longer, all of the owners successfully trained their dogs to complete a down/stay on a targeted bed when visitors came to the door and also reported significant decreases in problem behaviors associated with greeting at the door. (Note: The study protocol did not include removing the device from the targeted bed).

Study 2: The researchers in this study asked whether dissociating the trainer from the +R by using a remote delivery device would influence dogs’ responses to a known command. The study design manipulated how +R was delivered to dogs while owners asked their dogs to “sit” and to “down”. One group of owners directly reinforced their dog with a food treat while the second group reinforced using a remote delivery device that was located next to the dog. After the practice session, the dog’s response to the owner’s commands was measured with the owner either standing next to the dog, 10 feet away, or hidden behind a screen. Results: All of the dog responded well to both types of positive reinforcement. Performance rate during the test phase (no +R given) was similar for the two groups when the handler was standing close. However, when the owner moved away or was out of sight, dogs who had been reinforced with the remote device performed better than dogs who had been reinforced directly by their owner. Performance declined in both groups, but it declined less in the group that had been reinforced with the device. An important note is that while the handler moved away from the dogs, the device did not. Rather, it remained where it had been during training, immediately next to the dog. (This is equivalent to the device remaining on the bed or platform in targeted training).  Therefore, a significant difference between the two groups was that the “opportunity for reinforcement” as represented by the device itself was still very much in evidence to dogs who had been previously trained with it, but the handler was not.  (One is left to wonder again, what would be the results if the device had been moved as well?).

Ally’s Training: So, here is where we are with our little gal’s training. Ally has rapidly learned to offer a down/stay on her pause table when the Manners Minder is present. She can maintain a down/stay for 10 minutes or more when I am training another dog, using a relatively “thin” intermittent and variable interval +R schedule programmed on the device (30 seconds or more). The caveat is that she is successful with this provided the training that I am doing with the other dog is not something that is highly motivating to her, such as retrieving or Nosework. Conversely, when training those activities with Cooper or Chippy, I reduce the schedule to ~ 10 seconds and she can (usually) maintain her stay. Since Ally is just 10 months old, is a very high energy field Golden, and literally lives to retrieve, I consider this to be a great success and would say that at this level, I am very pleased with her progress and with the Manners Minder approach.

Ally and Treat & Train 3

ALLY OFFERING DOWN/STAY WITH THE MANNERS MINDER

Next Steps: My goal with Ally is the same as with my other dogs – to have a reliable down/stay on the pause table while she is not currently being trained. Because I interchange dogs often during training sessions, I would like to remove the device altogether and have a solid stay that is “Manners Minder-Free“. To accomplish this, I must shift Ally’s focus for her +R away from the device and back to me (the source of click/treat). I am gradually reducing the frequency of +R from the device by increasing its interval, and then stepping in to +R in the breaks.

Reinforcing Ally

POSITIVELY REINFORCING ALLY’S DOWN/STAY WITH CLICK/TREAT

The results of the 2016 study predict that Ally may have some reduction in response when I move further away from her. However, it also predicts that keeping the device present will mitigate those mistakes. Therefore the big question continues to be one that the research has not yet addressed: “What will happen if/when I remove the device itself?”

Bye-Bye Manners Minder:  Some trainers who use these devices solve this issue by not having it in the first place – they don’t remove the device. They keep it on the dog’s bed or other targeted area and simply modify the intermittent schedule of +R that it delivers. Okay, well, call me a purist, but I would like to teach Ally to offer a solid down/stay without an enormous cue sitting there like a new-age,  belching, vending machine. Maybe I want my cake and to eat it too….but, like her brothers, I would like Ally to have the opportunity to watch training and get some of those demonstrated observational learning benefits that we recently learned about.

And, here it comes……there is something else that has been niggling at me about this device………

soapbox

UP ON MY BOX AGAIN

Is it a down/stay or is it an obsession? I have noticed a clear difference between training Ally to stay using the Manners Minder and my experiences training my other dogs using a more traditional click/treat approach. First, before Device Lovers out there start sputtering and spamming, I totally get that this device works. It actually works almost too well. Ally is less than a year old and I have a steady, if rather frenetic, platform stay with her. However, I have to question whether this stay reflects Ally having an understanding of “I maintain a down/stay on my table until it is my turn to train” versus a more insidious reflection of; “I am obsessed with this little machine that occasionally and somewhat unpredictably burps out a treat at me“.

There are definitely signs of the latter. When Ally sees the device, she gets excited and immediately books it for the pause table. When it beeps, she fixates on the tray with an intensity that borders on that of, well, an addict (hello dopamine). The tiny little treat arrives and she is back at it, staring, staring, hoping to hear that next beep.

We all know that look.

Staring At Phone

In addition to these signs of device obsession, Ally also shows varying degrees of frustration. She becomes conflicted between staring at the device (a look I am starting to loathe) and watching one of her brothers engage in something fun on the training floor. Certainly, my dogs all show some frustration (barking, excitement) when they observe another dog retrieving or finding a scent at Nosework. But this is different in some crucial way because Ally rapidly and frantically vacillates between staring at the device and trying to keep up with what is going on around her.

Bottom Line: My opinion and these experiences are not meant to disparage the use of remote food dispensing devices in dog training. I value the rapid response that Ally has shown to using the Manners Minder to train her pause table stay. However, I do worry about the obsessive nature of her response and I question how things will go when we begin to remove the dispenser from the table. I also wonder if what appears to be a down/stay when we describe it using observable behaviors may in actuality be something else – an obsession with a technology and the absence of learning. Whether this intense focus is something that I can segue into a device-free down/stay that is reinforced and maintained with click/treat with Ally remains to be seen. It also remains to be studied or reported in the research, something that I hope will be remedied in the near future!

Happy training and stay tuned!

Only Have Eyes for You

Eye contact is one of the first things that I teach to my own dogs and is a basic behavior that we teach to all of our students at my training school, AutumnGold.

Cooper Default Eye Contact

COOPER PRACTICES HOLDING EYE CONTACT

In our training classes, we introduce eye contact very early because it is easy to teach and provides rapid and positive results to owners who are often frustrated with their young and exuberant dog’s lack of attention. It is also a great method for teaching targeting and timing skills.

Really, what’s not to like?

PRACTICING DEFAULT EYE CONTACT IN BEGINNER CLASS

Well, until recently, I thought, nothing at all. However, a newly published study motivated me to think a bit more deeply about the behaviors that we train dogs to do and how they may, however subtlety, influence our dogs’ social lives. It has to do with tests of social cognition; specifically how dogs may or may not use human gaze as a communicative signal.

Following gaze as a social behavior: The inclination to follow the gaze of another individual is considered to be a socially facilitated response. It makes sense of course because one of the ways that social beings communicate is by attending to what others are paying attention to. Gaze following behaviors have been demonstrated in a number of social species that include chimpanzees, wolves, several species of birds, domesticated goats and of course, humans. Dogs have been shown to be able to follow human gaze and other intention gestures such as pointing when engaged in an object choice test (i.e. when they are being asked to choose between a series of cups holding food). However, evidence for the dog’s ability to follow a human’s gaze toward distant space (i.e. when food choice is not involved) has been conflicting and inconclusive.

Wolf following gaze    Dog Following Gaze in Object Choice                     WOLVES CAN DO IT                                    DOGS CAN DO IT FOR FOOD CHOICE

Why are dogs different from other social species?  Currently, there are three working theories that attempt to explain why dogs may not consistently demonstrate gaze following:

  • Habituation hypothesis: This explanation suggests that dogs who live closely with people gradually lose their innate tendency to follow human gaze because we gaze at a lot of things that are not relevant to them. Over time, the dog will habituate to this and stop responding. (Face it, in today’s world, many of us spend a lot of time staring at things that hold absolutely no interest to our dogs. Consider our use of computers, TV sets and Kindles, to name just a few).
  • Formal training hypothesis: A second theory, and one that is not mutually exclusive of habituation (i.e. they could both be in play here), is that dogs who are formally trained to offer eye contact with their owners, either on cue or as a “default” behavior, are less likely to spontaneously follow the owner’s gaze into space because looking into the owner’s eyes is a behavior that directly competes with turning away to follow gaze. (This is the hypothesis that could put a bit of a kink in my undying love for “default eye contact” training).
  • Lifelong learning hypothesis: A final theory that is in direct opposition to the habituation hypothesis poses that because dogs who live in homes are repeatedly asked to look to their owners for direction in many informal situations, that they actual may become better, not worse, at following our gaze. Examples of this are communicating to your dog that it is time for a walk (looking at the door), time to eat (gazing at the food bowl or towards the kitchen) or time for a game (searching for the favorite ball). So, in effect, the lifelong learning hypothesis works in direct opposition to the habituation hypothesis and predicts that dogs who live in homes should be quite proficient at gaze-following with their humans.

So, which of these theories (or combination) might be in play when our dogs are asked to “follow our gaze”? A group of researchers at the University of Vienna in Austria’s Clever Dog Lab decided to ask a group of Border Collies.

Multiple Steves

BORDER COLLIES LOVE PARTICIPATING IN STUDIES

The Study: In a cleverly designed experiment, the researchers tested all three of these hypotheses. First, they selected 147 dogs, all Border Collies living in homes as family pets. The dogs were between the ages of 6 months and 13 years. Using this wide age range allowed the researchers to test the lifelong learning and habituation hypotheses. To test the formal training hypothesis, the degree of training that each dog had received was assessed using an owner questionnaire. Dogs were classified into five categories, ranging from no formal training to extensively trained. A group of 13 additional dogs acted as a positive control group. All of the dogs completed a series of three experimental phases with a familiar trainer (one of the researchers):

  • Phase 1: In the first phase (untrained) the trainer lured the dog into position in front of her and lured or cued the dog to gaze into her eyes. As soon as the dog initiated eye contact, the trainer turned her head quickly away from the dog to gaze towards a door (test condition) or to look down at her feet (control condition).
  • Phase 2: In the second phase, the dogs in the test group were trained to offer and hold eye contact on command. The 13 dogs in the positive control group were trained to touch a ball that was sitting on the ground with their paw. Clicker training was used to teach both behaviors.
  • Phase 3: Following successful eye contact or touch-ball training, the dogs were retested using the techniques described in Phase 1. Instead of luring the dogs into place and to offer eye contact, the test dogs were cued to offer eye contact and the control dogs were cued to touch the ball before the trainer shifted her gaze towards the door or to her feet.
Dog Following Gaze Toward Door

EYE CONTACT FOLLOWED BY GAZING AWAY OR AT FEET

Results: Here are the researchers’ findings:

  • Some dogs follow distance gaze: In the pre-trained phase, about half of the dogs (48 %) spontaneously followed the gaze of the trainer towards the door.  Although the age of the dog did not significantly influence gaze-following, young dogs in late puppyhood and geriatric dogs were more strongly inclined to look at the door than were adult, middle-aged dogs. The absence of a clear age-effect is evidence against both the habituation and the life-long learning hypotheses.
  • Training eye contact interfered with gaze following: Following clicker training to offer eye contact, the number of dogs who followed the trainers gaze towards the door significantly decreased. The dogs who were trained to offer eye contact were also less likely to follow the trainer’s gaze toward the door than were the dogs who had been trained to place their paw on a ball. (In other words, it was not just the training that caused the change – it was specifically training for eye contact on cue.)
  • Formal training reduced gaze following: In both the pre-trained and the post-trained tests, dogs who had received more formal training with their owners were less likely to follow gaze towards the door than were dogs with little or no formal training experience. Because the dogs had a variety of training experiences, (for example obedience, agility, nose work, tricks, freestyle, search and rescue and herding), it was not possible to identify the effects of specific types of training (a subject the authors identify for future study).
  • Study limitations: Yes, the study used just Border Collies, and yes, indeed, as a breed, they are quite the smart little peanuts. Not only are they highly trainable, but they also have a very strong tendency to look to humans for cues. The researchers acknowledge this and open up the question of what, if any, breed or breed-type differences might we expect to see in distance gaze-following behaviors? This is certainly a topic for further (if difficult to accomplish) investigation. A second issue might be the use of a door as the focus point for distance gazing. Certainly doorways are not without meaning to dogs as they are conditioned objects that predict people coming and going and opportunities for walks, which would influence a dog’s tendency to attend. However, it is accepted that individuals tendency to follow gaze more readily toward relevant objects. Of interest in this study is the change in those tendencies in response to training.

Take Away for Dog Owners: The researchers in this study were the first to show that a relatively high proportion of dogs living in homes are likely to follow a person’s gaze towards distant space. In other words, they use our social cues to learn about and respond to our shared environment. Many people know this and probably will say that their dogs demonstrate this daily. However, in my view, the more important implications of these results are what they tell us about our ability to inhibit, albeit with the very best of intentions, our dog’s natural social behaviors. In the study, when the same dogs were trained for a short period of time to offer eye contact on cue, the training interfered with the ability of at least some of the dogs to follow gaze. The data also showed that lifetime formal training has an inhibitory influence upon this form of social cognition in dogs.

Why should we care?

Personally, these results led me to think a bit more carefully about when and how often I ask for default eye contact with my dogs. If one agrees that social cognition, the ability to understand and respond to the social cues of others, is an important part of a dog’s life quality, then we should make conscious decisions regarding the types of training that contribute to or detract from our dogs’ natural social behavior. I am certainly not advocating an end to training eye contact. For me, it remains an important behavior to teach to dogs because eye contact contributes to strong communicative bonds and facilitates learning. One cannot really teach new behaviors after all, if we fail to have our dog’s attention. Rather, I am suggesting that we consciously strive for a balance between those training activities that require our dog’s undivided attention and those in which we encourage dogs to use their cognitive skills and work independently.

For example, at AutumnGold we offer both Canine Freestyle and K-9 Nose Work as advanced training classes. Freestyle is tons of fun for dogs and owners and  the precise training that it involves teaches dogs body awareness, complex behaviors and chaining. Similar to obedience training, agility and many other dog sports, this training requires clear communication between trainer and dog, and eye contact is an important aspect of that communication. K-9 Nose Work on the other hand, encourages dogs to work more independently, using their scenting abilities to find a hidden object or selected scent. Like many trainers, we have found that there are very few dogs (and owners) who do not absolutely love these Nose Work games.

I am the first to say that I love having my dogs attention via eye contact, especially when we are training complex tricks, obedience exercises and Freestyle moves. However, it is every bit as exciting for me to see them work independently to find  a hidden scent, play tug with their doggy friends, retrieve a hidden toy, or have free swim time in the pool. For me, these data served as a reminder that allowing our dogs to attend to their social environment, to work independently of us, and to practice (and be allowed to show) their social cognition talents are as important (and fun) as are training for good manners and canine sports.

Happy Training!
