From the book:
John and Jenny were just beginning their life together. They were young and in love, with a perfect little house and not a care in the world. Then they brought home Marley, a wiggly yellow furball of a puppy. Life would never be the same.
Marley quickly grew into a barreling, 97-pound streamroller of a Labrador Retriever, a dog like no other. He crashed through screen doors, gouged into drywall, flung drool on guests, stole women’s undergarments, and ate nearly everything he could get his mouth around, including couches and fine jewelry. Obedience school did no good —Marley was expelled. Neither did the tranquilizers the veterinarian prescribed for him with the admonishment, “Don’t hesitate to use these.”
