Thanks for your reply! He is not male dominant at all – in fact, I have not seen him with any dog (male or female) that he didnt get along with. I have contacted BRAT and they have replied that they are going to talk to me this weekend and see about our next step. It is just soooooooo hard though. I want to cry every time I look at him because I love him very much and I just want him to have a good home with at least one dog he can play with. This has been the hardest decisionI have had to make in a very long time.
