This book is a bit dated and a little dry, but it is full of fun anecdotes and advice about training any animal with behavioral modification techniques. The author trained all kinds of animals, but seems to have started out training sea mammals. I used it for dog training advice, but there are also examples for how to modify behavior of other humans! We all respond well to positive reinforcement it seems.
I especially liked the outlining of 8 ways to get rid of an unwanted behavior and also this description of the beautiful bonding that happens during the training process. I feel it is true for myself and my dog... we are so much closer because of agility training we do together.
The trainer rapidly develops an attachment too. I remember Shanti the elephant and that wolf, D'Artagnan, with respect and I even have a soft spot for that dunderheaded polar bear. What happens, I believe, is that the success of training interchange tends to turn the participants into generalized conditioned reinforcers for each other. The trainer is the source of interesting, exciting, rewarding, life-enhancing events for the subject, and the subjects responses are interesting and rewarding for the trainer, so that they really do become attached. Not dependent, just attached.
