Adopted on Christmas Eve, Santa's Little Helper has become an integral part of the Simpsons' daily lives: fetching the paper every morning and chewing it up, digging countless holes in the yard, even running off with Homer's thumb.
In fact, Santa's Little Helper feels so at home with the Simpsons, he even eats meals on the table without being asked.
Flea-bitten and barely house-trained, SLH misbehaves at times, prowling the heating ducts at Springfield Elementary and defiling the holy water in places of worship. Yet, he escapes most punishments, winning over the hearts of the Simpsons with a wag of his tail, a lick on the face, and the steady, trusting gaze of his vacant brown eyes.
