Roxy is an 80 pound pitt bull, and Chewie is this tiny 10 pound rat terrier. I think it's a huge jealousy thing, because now Roxy won't let Chewie come near me, and Roxy has to be up my butt at all times. If she's not touching me she's whining, and I don't get it. Dog behavior is so baffling sometimes, but I guess she's just really jealous of Chewie.
