I had a female that went a week overdue. I took her to the vet and had xrays. The vet found that it was one large pup that had grown too big to pass through the birth canal. He had to do a c-section. The pups trigger labor when they are not getting enough nutrients in the womb. With one pup, they get penty of nutrients so labor is not triggered. If she goes later than a week, have xrays done. The pup looked a week old at birth. The vet said he looked like a baby rottwieler. He is now 7 moths old and only 3 pounds. |
