What is the puppy's name in '101 Dalmatians' that always stands in front of the TV?

I believe the dog's name was Lucky.

Yes, Lucky:

Voiced by Mimi Gibson, is the runt puppy from Pongo and Perdita who nearly dies immediately after being born. He is given the name "Lucky" because of being revived by Roger, who thawed him out by means of friction. He loves watching T.V. Lucky is usually played as a troublemaker, and often left behind because he never pays attention. Observant viewers will notice his dalmatian spots on his back form a "lucky" horseshoe.
