  A photo of her laying on her back showing, her belly would be best..but from the side shot, she does look fuller in her belly area...she also looks a large size York and with close vet monitoring, she may whelp okay even though the male is larger...if she has several puppies in the uterus, they can only grow so large, as oppose to one oversized one...be sure to get an xray around 55 to 58 days...  |
