"The Canine Mutiny" is the twentieth episode of the eighth season of the American animated television series The Simpsons.

[1] Bart fraudulently applies for a credit card and uses it to buy an expensive trained dog called Laddie.

He goes on a spending spree, buying the family expensive gifts from a mail-order catalog: smoked salmon and a radio-frying pan for Marge, a golf shirt for Homer, pep pills for Lisa and several things for himself.

When he fails to pay his credit card bill, Bart gets a call from a debt collection agency demanding payment.

When an exhausted Bart takes Laddie on one of his frequent walks, the collie saves the life of Baby Gerald.

At the ceremony honoring Laddie's heroism, Chief Wiggum decides that he would make the perfect police dog.

Bart visits Mitchell to beg for his dog back, but he sees that the man is blind because he fails to notice his parrot has died.

Chief Wiggum arrives with Laddie, who immediately sniffs out a bag of marijuana in Mitchell's pocket.

As Bart and Santa's Little Helper head home, more police officers arrive to enjoy the confiscated cannabis.

[4] The main plot of the episode came from an original idea that the family would be issued a credit card in the name "Hobart Simpson" which Bart would use.

Hank Azaria ad-libbed the entire sequence during the closing credits in which Chief Wiggum and Lou sing along to "Jamming".

[3] The authors of the book I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, Warren Martyn and Adrian Wood, called it "A sweet episode".
