Description by couchtuner for The Simpsons Season 8 Episode 20 : Marge lets Bart read her junk mail and he comes across a credit card application. He fills it out with the name “Santo’s Little Helper,” his dog. When the application is approved and he gets the card, he starts spending like a madman, not realizing how credit works. He even buys a collie named Laddie, this dog is so perfect, that he neglects his old dog. Eventually the repo men come to take back everything he bought, including one $1200 dog. Bart gives him Santa’s Little Helper instead of Laddie, but he soon misses his old dog and grows tired of the new one. Laddie gets local attention when he saves a baby’s life, so Bart gives him to the police and then searches for his old dog, and finds him living with a blind man. The blind man calls the police when Bart breaks into his place. When the police come, Laddie finds pot on the blind guy. Bart leaves with Santa’s Little Helper as the police smoke the blind guy’s stash.
