Mardelin is correct. Yes!! This can be very bad! This is called inbreeding and you do NOT want to do this (breeding mom to son). You can have some real problems. Show Breeders that I know will never do this!!!!
Yes, both males can father pups and yes, if you register them you will need to do DNA on the fathers and pups to find parentage, since one pup could have one dad and another pup could have the other dad.
