Mike and Bo

    In our last post we described the case of Millie, a cute and lovable little Springer Spaniel who, for the most part, was a great pet but occasionally beyond her control, would become irrationally aggressive toward her people (see "The Mysterious Bites: Ouch!"). I attributed Millie's problem to her genetically predisposed tendency to remain immature, a condition known as neoteny. She was incapable of controlling her emotions: if frustrated, she would lash out at her people and repeatedly bite them until the response was exhausted. This aggression problem has been identified as Springer Rage since it is common in this and related breeds, though not limited to them exclusively.

    For illustrative purposes, we can think of Springer Rage as if dealing with a person who does not grow out of the very infantile stage of throwing temper tantrums and striking out at the parents in frustration for insignificant reasons or just because the kid is in a bad mood. Our theoretical person remains incapable of controlling his temper as an adult thus becoming dangerous to society and a big problem for himself - not a bad or evil person per se, just one that can not control his temper.

   The neoteny hypothesis implies that since we want playful and cute baby-faced dogs as pets, we are breeding animals that stay psychologically immature. This is fine as long as the dog develops the necessary social skills, in particular control of antisocial emotions, to be able to survive and get along in a complex human environment. This does happen most of the times but at other times this fails to occur and creates a big problem: ergo the Springer Rage syndrome.

   So presently, I want to deal with a case of a nine month old yellow Labrador retriever named Bo with this kind of problem whom I was able to help because of what I learned from Millie. Bo only weighed 50 pounds - relatively small for the breed but growing fast. He lived with his owner Mike, a single man, in a large two-story home with lots of room to roam.  Mike had never had a dog, and since he now lived alone, decided that a dog would be good company for him. When I arrived at the home, Bo greeted me well enough, he was excited, playful and very friendly: he seemed fine to me. The problem was that Bo had the habit of picking up things and carrying them in his mouth, which Mike could most of the time take from him without a problem, but occasionally Bo would just lunge at him ferociously and without inhibition, try to bite him in order to protect the item from Mike. As a small puppy this might have been cute, but now, at nine months old, he was getting dangerous to live with.

    Mike had discussed this with the veterinarian who diagnosed it as Springer Rage, meaning that the problem was neurological and that there was no cure: the dog had to be euthanized. As Mike was telling me this, I noticed that he was having a tough time with it –very understandable; he explained that he did not have many friends and that Bo was really his best buddy. Mike was also undergoing psychotherapy for depression and anxiety disorder. The prospect of losing Bo would be devastating for him, he said. As I was taking in this sad narrative, Mike's suffering and conflict were palpable and I also noticed that Bo went over to Mike, put his head on his lap, sighed a deep sigh and looked up at him trying to make eye contact while swishing his tail slowly on the ground: no question in my mind that Bo also picked up on his sadness and was showing great empathy and solidarity with Mike - not an uncommon occurrence with dogs, who are after all biologically destined to be social animals with predisposed potential to develop complex social and therefore psychological skills.

    I pointed out Bo's behavior to Mike and asked him to interpret it: Mike was aware of it and explained that when he was upset, Bo seemed to know it and do that, follow him around and sometimes tried to get him to play by barking and play-bowing to him while carrying a toy in his mouth; Bo was keenly attuned to Mike's moods so I asked him how he responded to Bo at these times and his answer was complex: on the one hand it was very difficult for him to play when depressed but he also felt guilty about not paying attention to the dog, so he would force himself to focus on Bo and for short moments would forget his troubles. 

    At other times, he just could not deal with it and felt emotionally paralyzed and Bo would just hang out by him. I asked Mike again how he felt when this happened and from his answer it was clear that Bo was very helpful in providing comfort by his presence and attention: Bo's demeanor and attentiveness, he explained, was a tonic for him. What blew my mind was that because Bo was so attuned to him, he occasionally was capable of truly coming out of his depression and according to his narrative, a heavy weight would lift from his chest which I assumed to be the physical manifestation of his depression.

     Mike loved to go outside in the yard, play ball or throw a toy for Bo to chase, which they did often. However, it was also at these times that Bo would lose it and attack Mike when he tried to take the toy from him thus making things more conflicting and emotionally wrenching for Mike.

    Nevertheless, it was obvious that these activities were very useful for Mike, so I prodded him to go deeper into this and his relationship with Bo. Through our conversations in the following weeks where we worked on Bo's aggression, Mike gradually became more aware, more conscious, that during those moments with Bo and without aggression, his depression and anxiety would go into abeyance for a while, so we continued with our talks and envisaged Bo's state of mind and how he focused on the present and how he influenced Mike to follow suit and since Mike saw how this focusing-in-the-present business helped him, it gave credibility to the idea that Bo (if we could solve his problem) could teach him that life is to be taken a moment at a time and that by observing himself, he realized that his depression and anxiety are more based on unrealistic and imaginary afflictions: the anxiety would disappear momentarily when engaged with Bo and his needs. We talked about this extensively.

    I asked him to take the concept of time into account when discussing his problems, that is to take the past present and the future into consideration and to place his problems in this perspective. After some time of coaching, he began to see that these were associated with impending fear of the future, which was based on his experiences in the past but that in reality they now presented no heavy and insurmountable problems. He was, after all, a relatively successful commercial artist with a fine home in a beautiful old neighborhood with majestic ancient oaks that he had inherited from his parents and his health was good.

    Therefore, we discovered that Bo was his best medicine, thus if we had to put Bo down, it would be truly catastrophic for him. Now I was anxious because it was up to me not to let this happen. So, given the diagnosis and my thoughts about Millie, Mike and I went to the local hardware store and bought the largest, heaviest and thickest pair of welding gloves we could find and went back to deal with Bo.

    It was obvious that Bo’s aggression was triggered by uninhibited possessive tendencies, not unusual in very young pups. Puppies play and compete with each other all the time and when very young, the aggression is not inhibited. Inhibition or control of aggression develops later on with the advent of maturation and socialization; in fact we can describe socialization as the ability to handle and control antisocial emotions and behaviors, which is after all the most significant skill that a social animal has to learn. So the neoteny hypothesis states that some dogs do not grow up emotionally enough to be able to inhibit these tendencies as a matter of maturation but that does not mean that these tendencies can not be modified or eliminated, which is what I was going to do with Bo.

   The method I chose to drastically reduce or eliminate this biting behavior is a combination of a well-established procedure in the behavior modification literature known as simple extinction and a not so-well known behavioral nuance called massed trials.

   The extinction procedure basically involves the repetitive presentation of the stimulus configuration that triggers the undesirable behavior without reinforcing it and the massed trial process involves the presentation of these trials one after the other without pause. The logic behind these methods is that if a behavior is not reinforced, it will disappear, or go into extinction and if it is repeated without pause, the response will become temporarily exhausted. Therefore, the combination of non-reinforcement and exhaustion should work together and eliminate the inappropriate response and set up new non-competitive and non-aggressive associations and experiences or learning.  In our situation: a) we wear the gloves to protect our hands from the bite, b) do not let go of the item, c) do not get uptight about it d) let Bo bite until he quits and e) do it all over again immediately.

    So I put on the gloves, which, in spite of having relatively large hands, were huge on me; I had plenty of wiggle room and could move my fingers out of the way when Bo bit down on the gloves. Given that Bo was a retriever and fiercely attached to whatever he carried in his mouth, the thwarting of his desire to possess the object was the immediate trigger for the attacks, I went to work.

    Like with Millie, I threw his favorite toy for him and prepared myself for the bite. The bite came as predicted and he lunged for the gloved hand where I was holding the toy, wiggled my fingers away and Bo continued to bite: I was fine, I did not get hurt. I let him bite to his heart content and after four consecutive bites, he quit, did not get the toy and no one took him up on the challenge (non-reinforcement) and right away threw the toy again (massed trial) for him to chase. 

    He responded well enough, chased it but his enthusiasm was diminished due to the previous tense experience and conflicting emotions. He nevertheless brought it back with some degree of uncertainty, which was good: we were engaging his emotions. I took it from him without incident, threw it again and Bo brought it back; he bit at my gloved hand again but this time he only bit twice and not as intensely as the first time: the energy of the bite was being exhausted, the result of massed trials. I threw again; he chased and crashed it, his enthusiasm improved. He let me throw it about seven or eight times, then bit into my gloved hand again but the bite had very little energy by then. I threw it again; he jumped on it and was happy (the uptightness was disappearing), brought it back and seemed to have forgotten about the bite. All aggression had disappeared for the moment and we did this a few more times without incidents and Bo was all smiles and wagging his tail happily. So was I.

   We waited for about a half hour while Mike and I talked and then I had him do the same thing. We counted the number of times that he could take the toy from Bo before he would bite: on the first set Bo bit at Mike's gloved hand after the fifth trial. The bite was a bit more intense than the last incident with me but still much less than the first trial. It was light enough that if Mike had not been wearing the gloves, it would not have penetrated his skin. We continued to do this a few more times and Bo just got into the retrieving game without getting uptight or biting at all, we praised the hell out of him and went out into the yard just to cool down. Mike chased Bo around a bit and played tug-of war with the gloves: the gloves were being associated with play and social excitement. 

   So we discovered that the aggressive response could be exhausted with these massed trials and developed a data sheet where we could record the number of trials and Bo's responses. I also set up obedience exercises for Bo where he would have to respond to a set of commands before he was fed, taken out, cuddled, or played with. These are very useful exercises for creating pro-social submissive behaviors or appropriate social skills necessary for domestic dogs living inside the home.

   We analyzed the data in the next few weeks and to my delight, Mike was enthused about the results. The dependency exercises were going great, Bo was more attentive to Mike; he would wait eagerly to be told what to do in order to receive his rewards and the gloved exercises were also going well and although he still occasionally attacked the gloved hand, we estimated that the intensity and frequency had diminished significantly. This trend continued and by the second month of this, all serious and uncontrollable attacks stopped altogether. The only remaining aggression was now associated with play where Bo and Mike played tug of war with the gloves but the seriousness had stopped.

   In conclusion, even though Bo remains a very immature animal, we were able through our procedures to train him to shift his behavior from fear of loss of a desirable item to a playful understanding that this is only a game. Furthermore, Mike, by becoming more observant of Bo and his focus on the moment, had developed a new and more enlightened perspective about his own problems: he is now reasonably capable of observing himself, is more accepting of his state of mind at the moment and more at ease with it when it does occur.

The Mysterious Bites: Ouch!

Early in my career I came across a case where, on my initial diagnostic visit, I was repeatedly bitten by a small female Springer Spaniel named Millie. The owners, a young couple with no children had explained on the phone to me that Millie was a wonderful, loving and sweet dog. They acquired her when she was a  pup and they were very attached to her but if they could not solve her biting problem, they were very seriously and regrettably considering euthanasia because she was too dangerous to have around; they were planning to have children soon as well. They were very upset, and told me that I was their last resort.  

 Millie, they explained, would very unpredictably lash out at them; her mood would suddenly shift and just attack them ferociously for no rhyme or reason and she had already laid some nasty bites on them.  This was serious stuff, I thought, and they had been putting up with it for some time. Millie was two years old when I was called on the case and she had been doing this for at least a year. They had consulted with their veterinarian who identified the problem as "Springer Rage" and recommended euthanasia. Since I had already heard of this behavioral diagnosis from other veterinarians but could not make sense of it, I did not buy it. This diagnosis basically maintains that the dog suddenly attacks for no apparent reason, the behavior is unpredictable and that the problem is rooted in an unknown neurological dysfunction that can not be treated. Although I was excited to finally see a case of this nature, I was also keenly aware of the people's anxiety on the phone. So I went to see them for the initial diagnostic visit not really knowing what I would find there or if I could be of any help.

The attack came relatively late into the interview when we were playing catch: Millie would bring her squeaky toy, drop it at my feet and then I would throw it for her. She went chasing after the toy happily enough and returned it to me to throw again. It was all normal play and we did this a few times. This interaction, which, in my experience, always made things better by inducing friendliness and relaxation, in this case backfired: it went the other way! Although the toy was still on the ground, Millie's demeanor suddenly changed and ferociously growled and attacked my hand before I could reach for the toy. Even though I intellectually expected a problem due to the description by her owners, I never expected this violence. My previous experiences with dogs, my formal training and my gut told me that there could be no danger at that point since we were at play and relaxed. I also had not challenged or inhibited her control of the toy at all and any changes in Millie's attitude would have made themselves evident long before the bite. Sudden shifts in mood of this magnitude are not normal and I ruefully concluded that the veterinarians were right on this point.

The first bite was hard and penetrated my hand, definitely a serious bite and it hurt big time but I did not jerk my hand away, I just left it there. Millie continued to bite while I watched the attack. She bit me five times in less than two seconds but with each consecutive bite, the intensity lessened and by the fifth bite she barely touched me. Of course the whole episode was exceedingly intense and my hand was bleeding profusely from the first and only penetrating bite. One can ask why would I leave my hand there and not protect myself? The answer to that is somewhat of a mystery even to me but I intuitively knew that I needed to let the behavior follow its own course without interference from my own erratic reaction to the attack, which would confound the results.

By then I had been thinking about the origins and triggers of this kind of aggression for some time and how it is maintained, so this was it! As a scientist I was thrilled though as a person my hand was throbbing. Millie was small enough - she only weighed around 30 pounds – “how much damage can she do?” I thought.  So I risked it, observed it and got my answer: the attack was definitely intense and without hesitation, which is not the norm; it was also paradoxically inappropriate to the situation and it was self-terminating. The behavior seemed to be stereotypical and rigid as if driven by genetically bound triggers in front of a specific releasing stimulus as in a fixed action pattern. All very different from the well-organized patterns and complexities associated with either defensive or offensive aggression and it did not make any sense given the situation under which it occurred. Very weird indeed and the veterinarians were once again correct: this was unpredictable and dangerous.  

At any rate, we cleaned up my wounds: 4 punctures from the first bite where the canine teeth penetrated and some bruising from the incisors. The subsequent bites did not penetrate; the second bite hurt and the third hurt a bit less. The fifth bite barely touched my skin and the dog quit on its own volition. My heart was beating madly but it was over and I got a lot of information out of it. Subsequently, Millie went away to sulk and one could tell that she was upset by the whole incident.

Well, we were all pretty upset, that was for sure. We continued with the interview after we took care of my hand and I found no other behavioral issues that would allow me to make sense of the aggression. Now I fully understood the description of the behavior if not its function. I finally left after spending three hours asking questions trying to figure this out during which time Millie remained upset. I was stumped and discouraged, I could not hang the incident onto any theory of behavior that addressed the issues of function and adaptation, control and development, but nevertheless we set up an appointment for the week after to give myself some time to mull it over, talk to some people and maybe figure it out.

Unfortunately, two days later Millie's mom called to inform me that they had discussed the issue in great depth and had decided that they could not take it anymore and Millie was euthanized that day. She was crying and I expressed my condolences to her but kept some distance from her suffering. I was both personally and professionally upset by the news since I had put a lot into it: my hand was still swollen from the bite and I wanted some pay off from that which was to continue to study the case. After we hung up I just sat quietly for a while thinking of my loss of opportunity but as I was observing myself in this state, something shifted inside which made me focus on poor dead Millie and how her mom was crying inconsolably when she informed me of their decision. I began to think not of my loss but of their personal loss, which after all was much greater. So I called them back and I listened more deeply to their words - their suffering.

I listened with my heart this time which made all of us feel better. I had a sense at that time of having come together with them and eventually spoke of finding them another puppy when they were ready for it. When I hung up, my turmoil was gone, I was still sad but now a heavy weight had been lifted from my chest. A few months later I helped them find a new puppy, a Staffordshire terrier, which they named Eli and he was a hoot. This dog wanted nothing to do with anything if it was not fun, my kind of dog. We became good friends, visited and went for many walks with Eli; sometimes we would speak of Millie and the things we could have done for her if I had known at the time what I know now; but that could not be helped. A few years later they moved out west but we still speak on the phone once in a while. Eli lived to be an old dog and now they have two children and a mutt named Oscar that they adopted from a shelter, they are all well.

From Millie and from other similar cases that I subsequently treated, I developed the hypothesis that due to selective breeding, some dogs are genetically over-bred to retrieve game which often produces animals that must carry something in their mouths at all times or most of the times and they become compulsively and neurotically attached to this habit and even though their competitive play behaviors are intact, the compulsive "holding behavior" short-circuits the social play and triggers the described rage response through an acute panic attack. Another factor that I suspect to be associated with the syndrome is known as the neoteny hypothesis which is described in the literature as the human propensity to selectively breed dogs to produce very docile and infantilized animals and I suspect that Springer Rage is highly associated with the lack of inhibitory mechanisms exhibited in the behavior of very young animals, who still do not have the capacity to learn complex social skills that require the inhibition of aggression. Clearly, the case of Millie has to be counted as "a failure" since I was not able to come up with a way to rectify the dog's dangerous behavior but it did start me down the path of new knowledge that was helpful to others in the future. 

On the next post, I will discuss these issues and some solutions to these "unprovoked" aggression problems.
