Will a baby dog survive in its mom if it was made by the moms brother?

If a baby dog, or puppy, is conceived from a mating between its mother and her brother, the puppy can still survive in the mother's womb. However, such inbreeding can increase the risk of genetic disorders and health issues in the offspring. As long as the pregnancy proceeds normally, the puppy will develop and be born healthy. It's important to monitor the health of both the mother and the puppies in such situations.
