Luckily for your pooch, you don't have to wait for her to gain weight to tell if she's pregnant. There are a lot of nutritional and other health precautions that you should take with a pregnant dog to keep her and her puppies healthy, so it's best if you learn whether she's pregnant as soon as possible.
A veterinarian can determine whether she's pregnant at about three weeks after breeding, either through blood testing, ultrasound, or a physical examination. Unless a breeder needs to know the specific number of puppies or the dog's health is in danger, a physical examination of the abdomen is generally all that is necessary.
