Tanisha is correct, you are much likelier to have genetic defects in the pups, since you are breeding dogs with the same parents, hence the same genetic heritage. For any recessive gene, each pup has a 50% chance of getting at least one from each parent. So, their pups have a much better chance for expressing genetic defects than would occur with parents from different parents. I also agree with Tanisha, there are so many dogs already in need of good homes, why breed more? Chihuahuas especially are fragile breeders, many should never be bred at all, it's not something for amateurs. Experienced breeders often lose the dam and/or the litter, and the vet bills far outweigh any amount of money you could get by selling the pups afterward.

They will have the same genetic heritage and it wouldn't be much different than if they were from the same litter. The pups would probably be weak and with all the dogs without homes you don't want to add to this. If you want to breed get two unrelated, healthy dogs at the very least.
