She immediately regrets her decision when Caitlin gravitates to the biggest, sloppiest dog in the pound, Jake. Megan's beautiful new home is now in shambles and, as Megan considers returning Jake to the shelter, handsome ballplayer Ben shows up claiming Jake is his dog, the regrettable outcome of his roommate leaving a gate open. Megan and Ben butt heads. Ben wants to take his dog and leave, until he sees that Caitlin loves Jake as much as he ever could. Now it is clear: the pound puppy everyone loves deserves no less than joint custody.
