Thank you for your post. Now, I do not feel as if I am alone. You know exactly how bad it is when those little dogs get into it! Is this a characterstic of Chis, or females? The other female, a Rottie mix, pretty much stays out of it and is a mellow dog -- a low growl or a stern look and the other dogs leave her alone. I do love both my Chis., but my husband is making noises as if we need to find a good, NEW home for one of them . If I keep them apart for long periods of time, it just seems to make it worse, as if the little Sophia has been saving up all day to get in the larger Queenie's face. I might add that Queenie is constantly by my side and at my feet, around the house and yard and during walks, but lately Sophia has started to run around me, ahead of me, is leaning on me, etc. and she needs constant reminding as to who is the leader. I think Sophia may be trying to make a bid for a higher status. It is driving me CRAZY! I will definately consider all of the suggestions presented here. Once again, Pet Talk members have proved an invaluable source of great ideas and supprt.
