Santa's Little Helper is a fictional dog in the American animated television series The Simpsons. He is the pet greyhound of the Simpson family. He was previously voiced by Frank Welker, and is currently voiced by Dan Castellaneta. The dog was introduced in the first episode of the show, the 1989 Christmas special "Simpsons Roasting on an Open Fire", in which his owner abandons him for finishing last in a greyhound race. Homer Simpson and his son Bart, who are at the race track in hope of winning some money for Christmas presents, see this and decide to adopt the dog.
