I really should be careful about what I teach my dogs.
When they were puppies, we enrolled them in basic obedience classes. The idea was to teach them to perform certain behaviors on command. We did this with a food-based system of rewards:
I say “sit.”
The dog sits.
The dog gets food.
Simple enough, right? Pavlov won a Nobel Prize for showing that dogs can be conditioned to drool at the sound of a bell. How did he do it?
