Do you have separate areas or crates at all? The main thing is having control of both dogs. They are older and sometimes introductions can be difficult and your girl is a little paranoid about being where she isn't quit sure she's supposed to be. Your boy needs to be able to sit, lay or be crated while she sniffs around, but it's the males house first, so that coulod work to your advantage. Like in breeding where you take the female to the male. But he has to be able to be controled to know that his being pushy is not to romantic. They're kind of like a teenage boy. They know the girl is pretty, but they're to awkward to be charming and suave. Instead they show them their bug collection and pick their nose.
You know you can call if you need help. If I'm no good at anything else I have always had a nack at training, since I was a little girl. It's the way I got my first show GSDs. I was 13 and 14 ad had done training for people who gave me show quality pups in exchange. I used to own a kennel when I was in my late teens, early 20s. Main reason was for training. I'm not very good at explaining in print, but I can honestly say, I'm very good at it in person. Bill used to love to brag about me training and even when I was bartending, I'd get people coming while i worked to ask for help, because someone sent them to me.
Oh and a Call Name is just that. The name you call them other than what is on their papers, the registered name.
