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, ninety-seven-pound streamroller of a Labrador retriever, a dog like no other. He crashed through screen doors, gouged¹ through drywall, flung drool on guests, stole women's undergarments, and ate nearly everything he could get his mouth around, including couches and fine jewelry². Obedience³ school did no good-Marley was expelled. Neither did the tranquilizers the veterinarian prescribed for him with the admonishment⁴, "Don't hesitate to use these."

And yet Marley's heart was pure. Just as he joyfully⁵ refused any limits on his behavior, his love and loyalty⁶ were boundless⁷, too. Marley shared the couple's joy at their first pregnancy⁸, and their heartbreak over the miscarriage⁹. He was there when babies finally arrived and when the screams of a seventeen-year-old stabbing victim pierced the night. Marley shut down a public beach and managed to land a role in a feature-length movie, always winning hearts as he made a mess of things. Through it all, he remained steadfast¹⁰, a model of devotion, even when his family was at its wit's end. Unconditional¹¹ love, they would learn, comes in many forms.

Is it possible for humans to discover the key to happiness through a bigger-than-life, bad-boy dog? Just ask the Grogans.
