When single mom Megan Nolan moves to a new town, she feels guilty for uprooting her ten-year-old daughter Caitlin. Seeing that Caitlin’s only friend is their neighbor Gail’s dog, Megan agrees to adopt a pooch of their own to keep her company. Megan instantly regrets her decision when Caitlin becomes smitten with the biggest, sloppiest dog in the shelter, a lovable but unruly pup named Jake. Just as Jake begins to destroy their new home, a handsome stranger named Ben knocks on her door, claiming Jake is his. A professional baseball player, Ben was traveling for a game when Jake ran away under the less-than-watchful eye of his friend Ryles and wound up at a shelter. When Ben sees how Caitlin’s love for Jake almost matches his own, he agrees to share custody with the little girl, despite immediately butting heads with bossy Megan.
