Please Help me find a Farting Dog!

I am looking for a certain cartoon I remember seeing as a kid (most likely late 80's or early 90's). I thought the scene I am thinking of was in the Family Dog, but seeing the episodes on You Tube, I never found what I was looking for. I remember a dog laying on it's side, sleeping and snoring. It then stops snoring and kind of fidgets a bit and farts. Then it goes back to sleeping. I could have sworn it was the dog from the Family Dog, but can't find this part on any of the shows. Can anyone helps please? Thanks! =)
