We just bought a 6 month old Cavalier about a week ago, we noticed that a couple times a day he'll just be laying there by your side, then he all of a sudden will yelp, turns his head and snaps his mouth back by his hind quarters and then runs to the corner and hides for a second. It only lasts for about 5 seconds. He almost acts as if someone's hurt him or something. Any ideas why he's doing this?
