Smiley is a dog that lived in an animal pound and was due to be put down.
History[]
Lisa decided to adopt him to save him, along with several other animals. She hid them all in the attic, where Bart found them.
After a tiger had mistakenly bitten his arm, all the animals had to be taken away. Chief Wiggum told Lisa that her animals would be taken to a pound and killed if she could not find a suitable home for them.
Bart felt empathy for Lisa and decided to use the money, that he raised for the operation he needed to play the drums again, to build a home for all the animals called Lisa Simpson Home for Abandoned Animals.
