Pregnancy in bitches can often be confirmed by a physical examination between 3 and 4 weeks after mating. Later in pregnancy, or if confirmation is necessary, pregnancy can be detected using ultrasound. We have a modern veterinary ultrasound machine which can both detect pregnancy and confirm that the puppies are alive and well. Ultrasound is extremely safe for both the bitch and her puppies. We are happy to examine bitches for pregnancy using ultrasound from the sixth week of pregnancy onwards.
Ultrasound examinations are not an accurate method of determining how many puppies are present.
