How long does it take for a dog to get an ultrasound?

Dogs have a gestation period of around 58-63 days and an ultrasound can usually be done after 28 days of pregnancy. There is variation in each individual animal and if a more accurate determination is required an x-ray can be taken around 45 days after gestation to confirm the number of animals. Give your pet the right amount of nutrition during pregnancy and don’t eat too much.
