Mommy, Daddy, Cassie, and Baby Louie welcome Marley, their new Labrador pup, into their family. But Marley doesn't stay a tiny puppy for long. He grows and grows, and the bigger Marley gets, the bigger trouble he gets into. Big, bad-boy trouble. Whether it's chewing Mommy's reading glasses or swallowing Daddy's paycheck, Marley is a dog like no other. He tries to be a good dog, honest he does, but everything he tries ends up bad. Then one day Marley goes too far. Will this family have to find a new home for their big, crazy, pure-hearted dog?

Inspired by John Grogan's bestselling memoir, Marley & Me, this heartwarming story shows that loving someone, flaws and all, can reap huge rewards.
