We are going through the same sort of situations but I don't blame it on the B****, although she is rather b****y!LOL! I blame it on the puppy, Boadie. He doesn't know when to stop. Nothing to serous yet but lots of small skirmishes. Uni has managed too school him two different times leaving a small gash on his chin and the second time one on his side. I'm going to try putting them in a down/stay next to each other next time. I remember this from Ceasar now, I think it may do some good. Boadie is now 14 weeks, We are making lots of progress but he still can't sit and wait with he's food bowl on the floor in front of him, he can however, sit for it, for a small amount of time with out getting too impatient. When we got Uni I thought what an great god to train, now I see that ever dog is different. Boadie is going to take a lot more work, we are really considering if we should neuter him or not now. At first we planed on not doing it because, he is such a rare color but now we are thinking we will have a better dog, less aggressive, stubborn and dominant, if we do go ahead and get him altered. I know that it is important to stay in control of the situation and be pack leader at all ties but I am finding it hard to find the line between playing and playing that is too aggressive. They play like sumo wrestlers! Boadie has managed to really do a number on Uni cheeks and lips, she has small scabs all over her face. I do feel for Uni and I let her show hi that she is not happy with he's behavior but she is not allowed to go after him, she gets a correction. However I find it so hard to get either of the to submit on their backs. I only try this int he most sever cases. Usually I give a loud sound and poke their neck when they need discipline. But I don't want to stop them from playing altogether, they play good most of the time, I don't think Boadie knows ho sharp his teeth are.
