Barking Dogs Don't Fite(1949)

Olive asks Popeye to walk her dainty new poodle Reggie, to his intense embarrassment. Bluto comes by with his bulldog, Killer, who tries to kill Reggie. The resourceful little pooch avoids Killer for a while, but is eventually caught, and when Popeye tries to help, Bluto takes him out of commission as well, until they both eat their spinach just before Bluto is ready to run them both over with a steam-roller.
