Does anyone remember a christmas cartoon about a "bad dog" and his family? Here's what I remember:
- the dog misbehaves
- he is sent to obient school
- the dog school teacher is old and nasty looking
- the family's house gets broken into and the little girl says "Mommy! the Bullfighter's goe!" the mom says "OMG they've taken the coffee maker!"
- dog saves the day
- it came out in the early 90's maybe

A long suffering dog (the little girl forces him to play dolly and dress-up, the young son is a cruel bully) comes up short when he must defend his home against two bungling burglars. The family returns home to find their belongings gone. The dog's taken to a special guard dog training camp where he's toughened up. When the burglars return to hit the house again, they find that the dog has become a much more vicious dog. The small dog bites one of the burglars and refuses to let go. He attaches himself leech-like to the burglars and they have no choice but to leave with him. The family's distraught when they come back home and find the dog has been taken. Eventually the dog causes the burglars to get caught and he becomes a hero.

It's pilot was first shown as an episode of NBC's Amazing Stories, and was later picked up by CBS as a short-lived series
