If you’re eagerly awaiting the arrival of a litter of Great Dane puppies, an ultrasound can confirm the pregnancy, detect the number of puppies, and ensure their health and development. Typically, puppies become visible on an ultrasound around 28–35 days into the pregnancy, with their tiny features becoming more defined as the weeks progress.
