We had a lot of good results

with german shepards, huskies, malmuts. Pit bull, or any of the more aggressive dogs didn't work out well. The

smaller breeds like australian shepard were problems carrying to term for females and mating issues for the males.

We didn't do artificial insemination. I don't know that I'd breed with a great dane, it might get to big to

manage. A full size wolf is a handful, something that big would be hard to deal with.
