The son got half the mother's genes and half the fathers genes. Since mother and son mated, those resulting puppies will have 3/4 the mothers genes and 1/4 the genes of its grandfather (the sons father). So therefor, more chance of genetic problems if there is any history at all in the pedigree of the mother.

Only breeders that REALLY know what they're doing should attempt inbreeding. They have to have a lot of experience and knowledge of genetics and know the history of their dogs' pedigrees several generations back. They have to know that there is no history of genetic problems and know what specific trait they are looking to breed for.

It's a mistake - it happened....you'll either have healthy puppies or you won't. I for one wouldn't buy an inbred puppy from someone who didn't know what they were doing. Too many risks...

I had a coworker whose two pittbulls bred recently (brother and sister from the same litter) and almost all the puppies died a couple days after birth. They just weren't healthy.

You are so correct about inline breeding! It can be done but you must know the history of your two dogs..... good luck, hope all comes out okay and you have healthy beautiful puppies.... FULL Brother & Sisister Always A No, No!
