Well after having all the issues with Rikku and our boston terrier fighting, we decide to really step it up, Did tons of research, and consulted a behaviorist. According to her, we have to get rikku spayed, (boston is spayed) we were going to wait till after her first heat, and now last minute at 8 months she is going in on monday. The behaviorist thinks that will help a lot, along with some other training, so hopefully it does.
