My Gucci aka The Gooch, takes things ALL The time!! It makes me nuts. He goes into the bathroom and takes whatever is in the garbage, goes into my daighters room and steals clips, socks, barbie clothes, ANYTHING! We know he has something in his mouth when he runs like a bullet into the dining room. We try to get it from him and it becomes Chase The Gooch around the dining room table time! I swear I've lost 5 lbs!
So I think it is just fun for them, a game. I do the treats thing too, and yell GIVE IT, and he does, but I think he does it for the treats too!
I guess we have to close all the doors!! LOL!
