I just had a litter of pups and had read your post and asked my vet what his thought were on it. He has had a cocker spaniel have a litter of 4 and 5 days later another pup was born,and he has seen it in cats also which is more common he said, so it is not impossible but strange that it can happen and that labor does not expel all the uterus contents.Makes me wonder do they stay dialated or does it all start up again to deliver the last one days later? |
