You're probably familiar with, or at least aware of, Disney's Air Bud series of movies. Beginning in 1997 with the eponymous Air Bud, the film series follows the exploits of Buddy, a golden retriever who can play sports on human teams. The dog played basketball in that first film, and then in 1998, the sequel Air Bud: Golden Receiver found him taking up football. Later films had him play soccer, baseball and volleyball (that's right, hockey fans: they made a volleyball film and then stopped!)
Beyond the original series, a number of Air Buddies spinoff films have been made, bringing the current acknowledged count to fourteen - FOURTEEN - Air Bud/Buddies tales.
