I am fascinated by how dogs perceive the world.
One of the things that dog experts and ethologists have been bringing to our human attention for a while is that dogs discriminate beautifully, but generalize poorly.
What this means in our training lives is that dogs notice all the little things that we, as trainers, tend to do the same every time. It is very hard for humans to randomize things; we fall into patterns so easily. Sometimes dogs’ noticing is very obvious. If I am teaching my dog to run a few feet to a pole and go around it and return, it’s very obvious to her when I get out the lamp pole or fire extinguisher or whatever we have been using to go around that that is what we are going to practice. It is _so_ obvious in fact, that the verbal cue I am repeatedly giving as she performs the behavior is probably just so much background noise to her. At the beginning stages of learning the behavior, this works to our advantage. I can get her to do the behavior just from context. But later, as we are concentrating on learning the verbal cue, it’s our job as trainers to vary everything else possible. So with the “go around” behavior, I would vary the object, my position with regard to it, the direction we are facing, the distance to the object, the room we are practicing in, whether my other dogs are there are not, and so on.
And you know what? Even then she probably doesn’t know the cue. I left out a big factor. She has been watching my body language the whole time. Just try teaching a dog to go around something without clueing them in to that with your body. (OK you herding people, I know you all have to do it all the time.) Sometimes we have to take the extreme measure of getting out of sight of our dogs to know whether they know the cue.
After we have winnowed out all the above factors is when the dog starts to understand that it is all about that little sound we were making. Some breeds are better than this than others, and experienced dogs learn it faster. But generalizing is something that none of us trainers can afford to skip.
There has been quite a bit written on reasons a dog might not respond to a cue. Here are three nice blog posts about it:
Three Reasons Why Your Dog Isn’t Responding by Eric Brad at Life as a Human.
The Disappearing Sit by Kevin Myers at DogLovers Digest.
“He Blew Me Off!” by Nicole Wilde at Wilde About Dogs.
Sue Ailsby in her Training Levels books approaches generalization in the best way I have seen in any book or system. She includes explicit instructions on generalizing in every behavior in the Levels. (Full disclosure: I helped edit the book.)
Sue writes in her colorful way about asking her service dog Stitch for a favorite behavior (spin to the right) in a new context:
I was THREE FEET from where I always ask her for this behaviour, holding a dish which was empty instead of full, and I was facing north instead of east. She wasn’t “blowing me off” or “giving me the paw.” She truly had no idea what I was asking her for. Those 3 little tiny differences changed what she saw so much that the behaviour seemed completely different to her.
Once you are in on the fun, it can be amusing at how dogs and humans perceive things differently. But this disconnect can be bad news for dogs. Force based trainers seem to glory in the idea that when this communication breakdown happens, their dog is indeed “giving them the paw.” I have heard this expression uttered more than once in complete earnest.
Burch and Bailey wrote in “How Dogs Learn,”:
Well-intended owners sign up for classes at their local obedience school, only to get instruction on heeling and figure-8s…….Obedience instructors who run classes designed around formal exercises think their training will ultimately result in a well-behaved dog at home. They firmly believe the behaviors taught in class will generalize to the home. But the majority of obedience class dropouts in a 1991 study told us they quit obedience classes because they saw no changes in their dog’s behavior at home. This suggests that training is not generalizing the way some trainers think it is.
The world of dog training schools and classes has doubtless improved since 1991. But at every obedience trial I have ever attended, I have seen handlers in states of rage or at least confusion at their dogs’ surprise inability to perform. Even if you attribute the dogs’ problems to “stress,” where did the stress come from? Changes in the dog’s usual training environment. Changes that in addition to differences in the visual environment involve strange dogs, strange people, new noises, a road trip, etc.
I have seen the furious trainer phenomenon once too many times. So I made a series of videos showing my dogs confounded by small changes in the environment, the props, and in one case, the effect of a previous reinforcement history.
In other words, I set them up to fail.
I admit it; I experiment on my dogs. I push the envelope at times. But just so you don’t think I am a complete meanie: in the videos they have already succeeded and been rewarded several times. After they fail, I give them an opportunity to perform an alternative behavior and get rewarded again. So from their point of view this is a normal training session with an imperfect trainer where one time they fail to get the behavior and fail to get the reward. The only difference is that this time, for once, I actually had a clue it was coming.
The Missed Cue
In the Missed Cue video, I move my dogs farther and farther from their mat in a boring hallway and cue them to go to it. It is a matter of inches between where they respond confidently to the cue versus where they react in utter bewilderment when I say it. Some viewers have pointed out that in addition to the difference in distance, the dogs fail when the starting place is near the end of the hall with an open door next to them. So yes, it may have been more than just the inches. But think how different that is from how our minds work. The same word doesn’t compute when suddenly there is a familiar bedroom door to our left?
Missed Cue: Paw Touch
In the paw touch video I let Summer practice her paw whack, a favorite behavior, on several objects, including a little basket lying upside down. Then I turn the basket over. Summer, who learned to fetch in 17 shaping sessions using that same little basket, is helpless in the face of that history. She fetches the basket proudly and prances around with it. Her discrimination is so fine that she reacts differently to the same small object depending on whether it is right side up or upside down.
The Missed Cue: Generalization
In the generalization video, Zani is doing the “go around” behavior I described above. I flummox her by substituting a short plastic box for the pole lamp we had been using. She interacts with the box with a variety of behaviors, then checks back with me for further instruction. I then substitute a fire extinguisher instead, which is a vertical object like the pole lamp. This time she figures it out. (Nowadays I would have handled that a little differently. Stay tuned for the next blog entry for more about that.)
By the way, I know that there are times when dogs understand what we are asking and make a different decision. But I believe that happens a lot less frequently than many trainers think. And when it does happen: that’s just a different training challenge.
I would love to hear from you readers about times your dogs surprised you by not understanding a cue. I hope to get some replies down below. Also if you have a video that would be great. Submit it on YouTube as a response to one of mine. (Send me an email if you don’t know how to do this.) Wouldn’t it be educational to have a whole string of these?
Discussions coming soon:
- Fixing what I broke (ideas about getting over these cue learning and generalization humps)
- Dog/dog resource guarding
- Superstitious behaviors
Thanks for reading!
