Turns out the blood glucose level has an impact on our dog’s ability to behave. When asked to (sit) stay for 10 minutes, a dog will have less ability to persist in a subsequent (unsolvable) task than if he had rested in a crate. The culprit? Blood Glucose Levels.
Other Executive Functions such as working memory are affected as well. You can find more detail on this study here.
In one test, the dogs used a treat release toy for a short time, then were asked to do a sit stay for 10 minutes, whereas the control group dogs would be in a crate for 10 minutes. Then they were given the unsolvable task of trying to get a hotdog out of the treat release toy. How long they persisted in this varied.
If they were part of the crate control group they persisted for longer than if they were a part of the sit stay group. Giving a glucose supplement improved performance for the sit stay group.
Listening to the presentation I wondered how these studies account for the differences in personalities, training and reinforcement history of the dogs that participated.
All my dogs are raised on a steady diet of self control exercises. Give it up to get it is the rule and each dog progresses according to his own ability. In the beginning the dog will stay away from a piece of food for literally a second or two, much later he will be asked to remain in a down while I walk away and hide a toy which he can then find. No force is used. Time and distance is determined by the dog’s ability and we always try to ‘train the dog that shows up, not the one you think you have’.
Once they are at this stage the fun begins and upon returning to the dog I request a sit or down, or a recall away from the toy before sending the dog on the search. In the beginning it will always take them longer to find the toy when asked to peform the additional behaviour. So we keep working on this and add difficulty slowly. Keep the search easy and add an obedience task; or make the search harder and do a direct find.
Back to my question. Each dog that I train has his or her own personality. Some are more relaxed and need faster and easier access to the reinforcer to keep them in the game, others need a lot of patience to build their ability to relax. There is no one size fits all training solution. I keep the error rate very low. The behaviour I observe is always a reflection of their personality and reinforcement history. It is intriguing to think checking their blood glucose level could explain what I observe in training?
I plan to send some of my questions to the presenter, I am hoping there will be a follow up seminar that will explain the meaning of this research in the daily practice of dog training.
