Sometimes things just don't add up. Using positive reinforcement to train a dog can be a fun, rewarding, and successful endeavor.... until a cat saunters into the room. Using food to redirect Buster’s attention away from Miss Kitty is often recommended, and as often it fails to diminish Buster’s fascination with felines. When Cat = 100 and Hotdog = 4, there's little chance that the dog will simply take his focus off kitty, especially if he's not hungry. In DOG ALGEBRA, Tammie Rogers solves the equation by offering a simple, straightforward, natural, and effective way to overcome training situations that positive reinforcement fails to resolve.
