Grammy-Winner Guests on DogTown

Music star Emmylou Harris calls for help with a vicious shepherd mix named Gunnar, leaving animal behavior specialist Sherry Woodard only a few days to come up with a plan to overcome his aggression. Theresa, an abandoned pit bull, has a mysterious mass in her belly. The dog has a history of skin cancer, so vet Dr. Patti Iampietro must do exploratory surgery to see if the cancer has spread internally. The unlikely combination of boisterous trainer John Garcia and painfully shy Little Girl proves rewarding for both, as John teaches the Catahoula leopard dog mix to trust the world — one person at a time.
