Behaviors that are perfectly natural for a dog can be frustrating to dog owners if they don't understand the dog's motivations, reactions, and needs. "Why Does My Dog . . .?" explains hundreds of specific canine behaviors and problems that the author has encountered while working with dogs for more than 20 years. Problems are listed alphabetically along with root causes and solutions for specific problems. The impact of diet, training techniques, and environment on a dog's behavior is clearly explained.
