Suggested by Destroyer Benji is a dog who has been in a lot of movies so you don’t want to underestimate him. That being said, Air Bud has this round. Not only is he a lot bigger and stronger but he’s just got more experience in things that are closer to a combat setting like sports. Benji would not be able to compete with Air Bud for long and would ultimately be chased off. Air Bud wins.
