how many days before you can x ray a pregnant dog?
<answer> You can x-ray a pregnant dog before the 28th day of pregnancy. <context> Counting Puppies. X-rays can distinguish between pregnancy, false pregnancy and thickening of the uterus in dogs, and are the most accurate estimate of litter size. Josie shouldn't have X-rays before her 45th day of pregnancy, as the radiation could harm her pups. The vet can give you an estimate of her litter size earlier, around the 28th day of pregnancy, by palpating her abdomen.
