Contact WCM and also get on some of the facebook pages if not all and ask questions and perhaps get a day out with lads working and breeding them and see do you like them.
WCM is right - I have seen quite a few now too and health problems can kick up - had one small beautiful game wee bitch under 11" that developed foul mouth (no one knew this would happen - but she is great to rabbits), had another male beast 14" 19lbs at six months that never dropped a second ball (went back to breeder). Bought in a bitch that was mad and dog aggressive - lost. Bought in a great bitch recently - nice on
