When a lost dog shows up at Caden's new house, the only thing his parents want to do is find its owners. But the only thing Caden wants to do is keep it. Thus begins a quest to convince his parents that the dog has no owners and belongs to them. His parents agree to keep her—as long as Caden cleans up after her. Except the puppy makes more messes than Caden expected, and he begins to fear the dog is more trouble than he can handle. Will Caden become a successful dog master? Or will he admit defeat and give up the venture?
