Bettina has to put on thick winter mitts to give her dog food, because he will bite her hand badly, if she doesn't. He is terribly possessive of food, and toys. She is also worried for her children. Dr. Stanley Coren arrives on the scene and quickly has the dog's behavior subdued. By the time he leaves, Jake, the Springer Spaniel, is eating out of their hands.
