Had an American Bulldog that snored, growled, barked and ran in his sleep. There were nights when I would wake up thinking someone had broken into my house and the dog was eating them alive, only to find the dog sound asleep. I used to think he was fighting lions in his sleep.
My boxer snores and farts when he sleeps. If the tv is on he tends to have bad dreams because his legs move like he's running in his sleep and his lips twitch like he's biting the hell out of something.
My GSP just kicks her legs, whimpers and barks. I think she is chasing squirels in her dreams. The wife's Cavalier on the other hand is not allowed to sleep in the same room as me. That bitch rattles the walls when she snores.
