Oh BOY... well I'm having some of the same issue's here w/Winston. If I pet Roxie he tries to bite her, but Roxie is so laid back she puts up w/it. If I tell him to stop he will... BUT my biggest issue is my grandson Marcus who is only 2!!! He's going thru this hitting everything stage, and when he smacks Winston it's starts the madness. Winston tries to bite him back, so I have to stay w/them both 24/7. It's hard because the reality is they are both TODDLERS I'm guessing since Winston & Brie are about the same age this is something that Bullies just go thru... hopefully they will grow out of this somewhat. I still think w/as many dogs as you have it would be a good idea to have the behaviorist access the situation. You will have to let me know what she thinks, maybe I will have to do something like that w/Winston!!!@ddnene she is quite the boss w the other 3. 2 of them are so old it doesn't matter...she can't do much to them as they just don't care, and don't go bear her...more of an annoyance unless I go to put the leashes on them. the big dog who is 10 is the one she gets into it w. You pet him, she goes after him, etc..and he tries w all his might to not bite her. He turns away from her while barking at her while she is going after him...no one has actually bitten each other..yet. I've noticed it becoming more intense and eventually one of them is going to get hurt. Plus, my son really needs someone non-family to explain how to behave. He loves her but she can't stand him in her face and of course that is where he goes. She bit him on the face a few days ago. She was asleep and he startled her I'm assuming..she bit and gave him some good marks. When he is calm, she is calm but to her, he is a litter mate to play w and she plays rough. So, I figure if she is like this at 9 mos, I can't imagine he it would be when she gets older. I think my hubby needs to hear it all as well as I need them both on board w me to help w her. She deserves it and so do we all if that makes any sense?
