Adaptation of John Grogan's bestselling memoir about an incorrigible Labrador retriever.

Marley is the yellow lab adopted by Grogan, a columnist for the Philadelphia Inquirer, and his wife. Their idea was to give them a taste of parenthood, but the dog proved to be a hyperactive handful. He wreaks havoc, gets kicked out of obedience school and gets even worse when the children begin to arrive, yet becomes an indispensable part of the family.
