My yorkie seems to be spoiled rotten or either she has a nerve problem. Whenever my sister brings her kids over to visit Angel goes nuts. She is fine unless they get to close to me. Then when they come close she barks and acts like she wants to tear them up. She doesnt like them to give me kisses or hugs. She has recently been biting at her back side and she has a bald spot from it. I have checked for fleas....nothing. Plus I always give her her once a month flea medicine. Could possibly the kids be getting on her nerves causing her to act this way? My other yorkie doesnt pay them any mind. I have been leaving a lot lately doing things and Angel has a fit to go. She is 3 and never acted this way before. I dont understand exactly whats going on. Any help would be appreciated.
