Sock a Doodle Do(1952)

A prize-fighting banty rooster, so slap-happy that he goes into a punching spree whenever he hears a bell, falls out of a truck and onto the farm where Foghorn Leghorn is in the midst of his usual sparring match with the barnyard dog. Foghorn and the dog use the fighter-rooster's manic punching against each other by ringing a bell once the rooster is within striking distance of their intended victim.
