Generally speaking, first generation mating of sibling dogs don't produce issues; that being said, it's "generally", after years of sibling interbreeding is where the deformities and other issues will show up. Talk to a couple vets --- if you get conflicting opinions, ask a couple more...plus do your own research, I think you'll find though this situation isn't optimum, it's hardly worth doing an emergency spay (something that cannot be undone) and forever rendering your dog unable to have puppies should that be something you choose do in the future.
Talk to the previous owners again and tell them you just want to make sure she's safe and ask them if there any way she could have been breed by any other dog. You'll have to trust what they say and I would agree this is a pregnancy that should be monitored closely. If you're not ready to handle a litter and have serious doubts you'll want to breed her down the road, have the spay done and be done with it all. Only you can make the decision as to what's best for you, your dog, and your family.
