Definition of Pregnancy

Pregnancy is the condition of having an embryo or fetus developing in the body. A fertilized egg goes through a series of cellular divisions during the first few weeks, and the embryo moves from the oviduct into the uterus, where it eventually implants. The female may show signs of morning sickness, including appetite loss and vomiting. She may also show subtle changes in personality.

The best time to determine whether a dog is pregnant is 26 days after breeding. Skilled practitioners can detect pregnancy by physically palpation; the fetuses feel like a string of pearls or a chain of grapes. This technique must be done carefully, because rough palpation can cause abortion. After day 30, fluid build-up in the uterus makes it more difficult to palpate puppies. By the end of the 4th week, fetal heartbeats may be detected safely by ultrasound.
