Ok, I feel much better now! I had a hunch it might of had something to do with her going into heat. She is about to be 7 months now and I was waiting for Gibson to turn 6 months so we can take them both in at the same time. So now that he is old enough they will get spayed and neutered very soon. She is so different right now. In the mornings when Gibson goes over to play with her she will growl and nip at him.... guess she isnt a morning dog.
