DON GONYEA, HOST:
Oliver was anxious all the time. He demonstrated compulsive behavior, and he howled every time his parents left him alone at home. Oliver was a dog - a Bernese Mountain Dog.
But he, like many animals, displayed some amazingly human psychological traits. That was the inspiration for Laurel Braitman's new book. It's called "Animal Madness." It looks at the mental states and behaviors of animals and how they sometimes mirror our own. Laurel Braitman joins me now from KQED in San Francisco. Welcome.
