This is surreal. First there were 6 puppies and then there were one? How did the first vet come to the conclusion before whelping that there were six puppies? Ultrasound? X-ray? Palpation? Considering the story as a whole, I would be worried that there were other pups that you didn't get back after the c-section. And no records? If your suspicions are true, this can't be isolated, and there are bound to be others with complaints as well.

Question to breeders: I have read here that singletons can be larger than normal at birth. Is this always the case, because this one doesn't seem to be.

So glad that your momma and pup are doing well.
