K-9 (1989)

Synopsis
James Belushi stars in this cop actioner about a loner narcotics officer who has to break in a new partner. The twist here is that the new partner is barely housebroken, but he's still sharp and keeps his nose close to the ground. Dooley (Belushi), who works on the San Diego narc squad, is an eccentric guy who has pizzas delivered to his car and likes a good steak. He is working on a stakeout of a local drug dealer when he barely escapes with his life as a helicopter blows up his car. When he asks the department for a new car, they give him a new partner instead --a police dog called Jerry Lee (Jerry Lee the Dog). Jerry's good at sniffing out the criminals but Dooley doesn't really hit it off with his new partner until the pooch saves his life. ~ Paul Brenner, All Movie Guide
