Sorry, not really advice about your dogs but i just wanted to say that i did a bit of reading last night about this breed and was amazed at thier history, especially the bit about how Hitler wanted to have all these dogs eliminated because of thier loyalty to thier rich owners while he invaded France. The french uprising didnt do them any favours either. By the sounds of things they are lucky to not be extinct ! What a shame that would have been to loose such a good looking pooch
Good luck with the breeding, hope it all goes smoothly.
