"The story of a family in the making and the wondrously neurotic dog who taught them what really matters in life. Is it possible for humans to discover the key to happiness through a bigger-than-life, bad-boy dog? Just ask the Grogans"--From publisher description.

Marley, a rambunctious puppy, makes himself at home while causing lots of trouble but then proves in a very dramatic way that he is a valuable member of the household.

Follows the life story of an exuberant Labrador retriever who gets into perpetual trouble and experiences a range of inspiring adventures.

John and Jen are journalists who are a newly married couple. Marley is the adopted puppy that no one wants, a high-strung lab who is virtually untrainable. Marley shreds cushions, destroys floors and walls and most everything in between. Instead of taking him to the pound, they love their dog and he faithfully loves them in return. John and Jen eventually have three children and Jen gives up her career to be a mom. John's career continues to advance...

Marley learns that no matter how tasty, he should not eat Cassie's homework, and wonders how to make it up to her.

Marley the dog is often in trouble, but during the first snow of the season he amazes his family with his good behavior.
