I remember watching this around christmas, so I am pretty sure that it is a christmas movie. But there was a dog that was lazy and was a horrible watch dog, and robbers broke in and stole everything from this family. The dad took the dog to have him trained as an attack dog, but when he got him back home the dog attacked him. It was a funny cartoon movie and may have been a made for TV deal IDK. I hope that someone can help me, this has been driving me mad for years.

Snoopy? Only lazy dog I can think of lol

Nope it wasn't Snoopy. This was a gray fat dog that was always laying on a rug, scratching a farting.

Sounds like my dad lol
