How is Dog Pregnancy Called?
Dog pregnancy, also known as gestation, is the period between conception and giving birth. It involves a complex process of development and physical changes that prepare the dog for whelping (giving birth).
Unlike human pregnancies that last nine months, dog pregnancies are much shorter but require equal attention and care. Looking for a vet near you? Visit our databes of vets.
