For small dogs, the scan is done with them lying comfortably on their backs, while medium to large dogs can stay standing. A small amount of gel is gently applied to the abdomen to help create clear images, and an ultrasound probe is used to carefully scan the area. This allows us to view the internal organs, including the uterus. If the dog is pregnant, the ultrasound screen will reveal the puppies, providing a clear and exciting confirmation.
