Here's how it works:
* Each puppy is born inside a sac of amniotic fluid. This sac helps protect the puppy and keeps it warm.
* Attached to each sac is a placenta. This is the organ that provided oxygen and nutrients to the puppy during development.
* The mother dog usually delivers both the sac and the placenta with each puppy.
However, it's not always a perfect one-to-one ratio.
* Sometimes, the placenta may be delivered separately from the sac. This can happen if the sac breaks before delivery.
* Rarely, a dog may retain a placenta. This is a serious issue that needs veterinary attention.
It's essential to monitor the birthing process closely to ensure the mother dog is delivering all the sacs and placentas. If you notice anything unusual, don't hesitate to contact your veterinarian.
