"Old Yeller Belly" is the nineteenth episode of the fourteenth season of The Simpsons. It originally aired on the Fox network in the United States on May 4, 2003.

Bart and his friends in his treehouse try to eavesdrop on Lisa and her friends having a tea party, and the treehouse gets destroyed in the ensuing fight. After they rip up a railroad and then goof off with their spoils, Marge gets the Amish to build a new treehouse for Bart. However, because the Amish know little about electricity, Bart's treehouse catches fire, and Homer is trapped inside, unconscious. Homer calls for Santa's Little Helper to save him, but Santa's Little Helper refuses and runs away with a roast turkey. Snowball II does, by clawing at Homer's chest until he wakes up.

Snowball II is worshipped as a hero by Springfield. The local dog park is even renamed the "Snowball II Municipal Cat Park". Homer declares in an interview that "I have no dog!" and kicks Santa's Little Helper out of the house for his cowardice.

Tied up in the yard and thirsty, Santa's Little Helper drinks from a can of beer by balancing it on his nose. Springfield Shopper reporter Dave Shutton takes a photo of it that appears on the front page of the newspaper. This gets the attention of Duff Beer, who announce that Duffman will be replaced with Santa's Little Helper, as their new mascot, Suds McDuff.

Suds McDuff boosts sales of Duff Beer, and the family's fortunes explode, causing Homer to embrace Suds for his success. However, this prompts Santa's Little Helper's original sleazy owner and racing trainer (from "Simpsons Roasting on an Open Fire") to visit the Simpsons and prove that he owns the dog by showing the interview footage of Homer disowning Santa's Little Helper. He becomes Suds' new owner and takes the family's fortunes to himself, much to the Simpsons' discomfort, and Homer is wracked with complete remorse for saying such a horrible thing on TV.
