My 6mo old Blue Tic Pitbull, jealous and bites my 12 yo GSP.
My 6 mo old Pitbull puppy, becomes very nasty, when my husband is patting our 12 yo old German Shorthaired Pointer. She will jump up on the side GSP is on and open her mouth and clamp her teeth on 12 yo. We have 5 other dogs and she never bothers them. When I holler...NO, she stops and gets down, but 1-2 times my husband has to pull her jaw open, to make her stop. Why is she acting this way? Is it fro her blood line or is she trying to be the female dominater?
