Most animals can mate with their own kin. If you were to mate with a sibling it doesnt automatically mean your baby would die. The European aristocracies have been inbreeding for hundreds of years with only minor cases of abnormalities and mental diseases. That doesnt give you permission to mate with your sibling though....eewwww
No, but their offspring have a very high chance of being affected. People who raise & train pit bulls to fight, inbreed them to make them mean and then train them to be even more vicious. Whatever you do, don't sell the pups. Part of the responsibility of owning an animal is to be cautious to never allow this mistake to happen.

Your female dog won't die, but the puppies would have a higher chance of health problems. One of the advantages of "churn" in the gene pool is that weaker genes aren't allowed to be expressed as frequently. When two closely related animals breed, there's less churn. I certainly would not sell the puppies to anyone. If you give them away, be sure to inform the new owners of their genetic history so they can be watchful for whatever health problems this particular breed of dog might be prone to have. If you don't intend to keep your dogs from breeding inappropriately, you really need to get the female spayed and the male neutered. It's a very good idea anyway for lots of other reasons.
