Remember Air Bud, the movie about the sad kid who moves to a new town and teams up with a basketball-playing dog to win the championship game for his local team? Well, it happened. A dog joins a basketball team because, according to the movie, there's no rule that says a dog can't play basketball (although there are in fact several other rules that should have prevented him from playing).
What about Soccer Dog: The Movie? It's a movie. About a dog that befriends a lonely kid and plays children's soccer, which drives the mafia crazy.

Actual dialogue. Did the mafia have money riding on this pee wee soccer game?
Or what about Cop Dog? That's about a boy and a dog who team up to solve crimes. (I know that might sound like a dumb idea, but this was made all the way back in 2008. It was a different time, no one knew how bad cocaine was yet.)
