How long does sperm live in female dog after tie. Can she conceive after breeding?
I bred my golden retriever with another golden, with three successful ties. I took her to vet on the 50th day to confirm pregnancy and size of litter. X-ray showed no puppies. If sperm can live for 5 days after last day of breeding she could have only been 43 days, and puppies might not have shown on x-ray.
