Love That Pup (1949)

Tom is playing with Jerry when a cute lady cat is delivered to Mammy for her to take care of. Tom is smitten at first sight.

Tom subjects Jerry to his usual harassment; but the cat finds a new enemy, and the mouse finds a new friend, in the canary of the house.

Jerry finds himself in charge of a foundling mouse called Nibbles, who is eager to steal milk from Tom's bowl and oblivious to the danger.

Mammy Two-Shoes threatens to throw Tom out of the house if he makes a mess. Jerry sees an opportunity to rid himself of his feline nemesis.

When Tom's harassment gets out of hand, Jerry writes to his Cousin Muscles, a tough inner city mouse, and asks for his help.

Jerry and his little French mouse friend are raiding while the king sleeps. They awaken him and he calls for Tom to give him an ultimatum: One more sound from the mice and it's off with Tom's head. The mice hear this and team up to torment Tom.

Jerry takes a midnight snack from the fridge unaware that Tom is watching him.

Mammy Two-Shoes replaces Tom with a younger cat who is a lightning-quick mouser. Tom and Jerry form an alliance in order to get rid of this dangerous newcomer.

Tom is all set to eat Jerry when a hawk swoops down and grabs Jerry. To get Jerry back, Tom poses as a female hawk and quickly finds his new lover to be more than he bargained for.

Spike has just washed his pup. Tom and Jerry's chase knocks him into a mud puddle. Spike makes Tom clean him up again and promise to keep him clean which of course is Jerry's opening to get Tom in trouble.
