The Karate Dog, 2004
Forget about the Karate Kid. In this action comedy, a canine named Cho Cho, voiced by comedian Chevy Chase, uses his knowledge of karate to help detective Peter Fowler investigate the murder of his Zen master in Chinatown. Sounds more like a knock-off of Turner & Hooch with Tom Hanks, but with martial arts and a talking dog.
