There is often a bit of discharge just prior to giving birth. Ideally, it would be best to have your dog
evaluated by a vet, and have an X
or ultrasound performed.
The X-Ray would show if the fetus's have calcified and how many there are. The ultrasound can check for position of fetus's, heart beats and size, and location,(i.e.: in the birth canal),
Therefore, it is best to have your dog evaluated by a vet for any pregnancy concerns.
