Maggie and Santa’s Little Helper
A former racing dog, Santa’s Little Helper‘s last-place losing streak finally ended when he was adopted by the Simpsons. Ever since, he’s been an integral part of the family: fetching the morning paper off Flanders’s driveway, digging holes in the yard (whether or not he has anything to bury in them), and devouring any people-food within reach. Oh yeah, and Maggie’s here, too!
