What Cesar Millan is to the west coast, Justin Silver is to the east: a trainer and behaviorist who, starting May 30 (and repeating June 3), will counsel New York City dwellers with problem pets or dog-related domestic issues in the CBS series "Dogs in the City." He'll tackle canine obesity and misbehavior, a dog that's having trouble adjusting to his owners' divorce, and help a couple in which the woman is afraid of her boyfriend's golden retriever. Silver is the founder of Funny for Fido, a nonprofit that raises money for homeless animals by producing a yearly stand-up comedy event.
