Augie wants his Dad to try a new formula he's just made. Doggie Daddy says no at first until Augie tells him that it's a slimming formula. Doggie Daddy puts it in his bath water and nothing happens. Augie feels like he's failed and goes off to try something else. Doggie Daddy is relaxing in the tub when all of a sudden, the formula starts to work and he shrinks. Augie comes back and finds his Dad on a bar of soap and he pulls the drain plug to get him out but Doggie Daddy goes down the drain. Augie runs and gets a plunger and plunges the drain hole and Doggie Daddy pops out of the sink drain.
Augie sets his Dad on the window sill while he goes and tries to fix a formula to help his Dad return to normal A bird is flying by and mistakes Doggie Daddy's tail for a worm and grabs him and takes him to the bird house and the bird flies off when he sees the little dog.
Doggie Daddy climbs down and finds a cat rummaging through the trash. He kicks the cat and tells him to get lost. The cat is surprised to see such a small dog. The cat starts chasing Doggie Daddy with a fly swatter and Doggie Daddy falls down a storm drain. Augie shows up and swats the cat with a broom and chases him off. he then uses gum on the end of the broom to get Doggie Daddy out of the drain. A policeman asks Augie if he's fishing for pennies and Augie shows him his tiny Pop. The policeman feels that it's time for him to retire because now he's seen everything.
Augie tells Doggie Daddy that the formula will wear off in four weeks and so he shrinks himself to keep his Dad company while he waits for it to wear off.
