Years ago my Dad had one, we took her to NC to be bred, the sire had Red Mange. The vet gave 1/2 of the pups the OK and the other 1/2 was infected, she had 13 and 12 lived. Talk about a royal pain in the arse, calf suckle and then 13 dogs baying at the moon.You need to be careful and make sure that either has a clean bill of health. Sandy was basically a large lap dog
