The best time for dog B-ultrasound is 45 days after mating. Only by doing B-ultrasound can you see the dog babies. Generally, dog B-ultrasound can be used to see whether the dog is pregnant, the number of puppies and the development of the puppies. In this case, a B-ultrasound before delivery can tell whether the baby's fetal position is correct and avoid dystocia for the dog.
Tip:
Under normal circumstances, dogs do not need to undergo B-ultrasound during pregnancy, as long as the dog is in good health.
