Carey bit Maggie (our daughter) on the face yesterday. First of all Maggie is ok, she has a scrape over her eyelid and two on her cheek with some bruising. Next, those of you who don't know me, Carey is a fantastic dog. Yes she has food aggression and it was my fault. We bought Carey a treat ball for Christmas, she had been locked up earlier in the day (two baby gates in the kitchen, lots of space) because she has seperation anxiety and will tear things up. We had come back from my mom's (Carey too) and I had forgotten to pick up the treat ball from earlier that day, Carey picked it up and before I get get to them Maggie tried to take it, Carey dropped the ball and bit Maggie on the face. We struggled with the decision of putting her to sleep and have decided not to, she is a beloved part of our family. And a loving, protective dog. But we must make certain this never happens again. Carey has always been very dominant, at times trying me, by not letting go of a toy or such. When Maggie gets to rough, she does a low grunt or growl. She has nipped at Maggie before as a warning, but in no way did I ever think she would bite her like she has. My problem is, we have to find a way to show Carey that even though Maggie is smaller, she is dominant over Carey. Those of you who know, please advise us on how to do this. I must also say that we have always taught Maggie to be gentle with animals, but she is very high spirited and like any two year old doesn't listen sometimes. She is punished and sits in time out but still has lots of learning to do in this area. Please Help!
