Can a dog have one premature puppy and stop labor and other puppy at a later date?

i think this is impossible because a dog cannot just have one pup.the mom has to give birth to at least mabe 4-6 pups at one time. Yes, a dog can have one puppy (live or dead) and go out of labour for a few days. A dog can also lose one or more puppies without losing the whole litter. I know of several cases where a dog passed one puppy and had more in 2 to 3 days. Retained puppies and placentas can be very dangerous so always discuss anything odd with your Vet.
