There is no doubt that Dagny is pregnant. During her previous pregnancy, we took her to the vet for an x-ray hoping to find out how many puppies we should expect. Unfortunately, the image was not very clear and we weren't able to count with much precision the number of pups in her belly.
This time, we decided to save her the stress and the radiation. We don't need any more proof of the pregnancy other than her big, fat belly. At this point it's pretty obvious that our girl is going to have puppies pretty soon. We are excited!
