Oscar is a dog, but he knows this new potbelly pig is going to be his best friend for life. Sure, Piggy pees while he eats, he eats while he walks, and he walks into trouble on a daily basis. ¿Meet Oscar, the deep-chested dog who just wants to play chase. When Piggy arrives at the family's home, he is quickly recruited as Oscar's best friend. The small pig grows bigger every day, and so does the trouble he gets into…much of it thanks to Kitty Bear, the family cat. She takes her antics a bit far, tricking Piggy and Oscar and framing them for spilled trash. Yet, for all her trouble-making, Kitty Bear isn't all bad. She also sneaks extra food to Piggy when their human family isn't looking. So, when a stray attacks Kitty Bear, Piggy is not able to forget it. Follow Piggy as he leads Oscar into a daring mission to protect the neighborhood pets from the violent stray that attacked Kitty Bear. Can he keep the plan from going a little astray itself?
