we got a tri boarder that we might let have 1 set of pups she's 2 now but think will leave her untill 3 or socannot blame you keeping one did the same with one of my cats litters, its just so tempting to keep them. hoping to have litter of border collies in a year or so (bitch only 1 year now) hope I can resist keeping one.
interestingthere is a higher risk of blindness and defness if you breed two merls together, it should not be done under any sercumstances, a breeding should not hapen even if only one is a merle and the other has a merle gene in its line ither
