I am certainly no expert but I had that same issue with Crackerman when he came home. He was always allowed to wander around the kennel with JT while he was racing. When he went to Signature, he had his own space. When he came home to live with us, everything was his. All the beds, all the toys, all the bones. Everything. That was all he knew. If he wanted to run over to the window to look out and he had to run over a hound or two on the way he did. This lasted until Dodger and Pooter got sick of it and they put him in his place. He is still a big, rude, clumsy galoot but he is trying. If he doesn't try quite hard enough he gets a growl or a mouthful of teeth in his face. He is learning. I am thinking your girls will eventually get to the point they are sick of getting run over and put a stop to it too. Could be wrong since I don't know your dogs. That was my experience though. Good luck.
