Karate Dog (2004)

Synopsis
When his Zen master is mysteriously murdered and a biochemical maniac sets into motion a devious plan to control the entire world, it's up to one karate-chopping canine to leap into action in a hilarious tale of man versus man's best friend from A Christmas Story director Bob Clark. His master may be gone, but Cho Cho is determined to find out who the culprit behind the killing really is. In order to carry out his daring mission he'll need a little human help though, and when Cho Cho teams with a brilliant but bumbling computer wizard, there's no mystery that this unlikely pair can't solve. Starring Jon Voight, Simon Rex, and Jaime Pressley. ~ Jason Buchanan, All Movie Guide
