They can have all kinds of problems as well as deformity. Brothers and sisters should never breed. You can breed a father to a daughter and a mother to a son but not sister to brother. It is also bad to down breed to the second generation. You end up with smaller and sickly babies then.

Can a brother and sister dog mate?
UNFORTUNALLY, YESSSSS!!!!!!!!! Yes, a brother and sister dog can mate and have puppies, but the puppies will most likely be deformed and have problems because they are so closely related. NEGATIVE. My sisters dog had babies with the brother, 3 times, none of them came out deformed or anything. We went to a Vet, he said it perfectly fine, because animals DON'T have the same affects as us humans. I agree
