Jack has recently begun driving us nuts by attacking the carpet. He seems to concentrate on two areas. I have tried everything to get him to stop but with no luck. I have tried several different cleaners suspecting he's picking up a scent of a long gone treat or something but he still attacks the same two spots. I've tried the bitter apple spray that broke him of his habit of chewing the throw rugs but it doesn't slow him down from his attacks at the carpet since he's digging and not biting. It's a really odd behavior and it would be a little funny if he weren't damaging the house. He barks at the carpet from about a foot away and then pounces on it like it's a mortal enemy and begins digging. The only thing that gets him to stop doing it is me getting down on the floor to play rough with him. My wife suspects that's why he attacks the carpet in the first place. This is one pug personality quirk I could do without.
