Five-year-old Alan is an easygoing boy who seldom cries or shows fear of the things around him. One day a large stray dog wanders into Alan's front yard. Alan is delighted to see the dog but reaches out too quickly to pet the dog's head. The dog is caught by surprise and bites Alan's hand sharply in self-defense. The following day, as Alan is running home from school, the same dog gives Alan a painful nip on the heel. After two episodes in which the same dog is associated with pain, Alan is dog-phobic: Whenever he sees the dog, he cries hysterically and runs away as quickly as possible. But Alan's fear is not limited to the stray dog. He seems equally afraid of his aunt's Irish setter, the next-door neighbor's German Shepard, and the French poodle that lives down the streetdogs that have never bitten him.
