No, the amount of radiation used for an x-ray when they do it at the correct time, should not hurt the puppies. However, when you x-ray the bitch for her pre-lims, and then for her ofa's and then prior to each litter being born to confirm pregnancy, and then maybe after a litter has been whelped to ensure there are no retained puppy, and then again in case of limping or injury, well it can add up. They do not like to do a lot of radiographs on humans, and will put a lead apron over the reproductive shtuff just in case. So, I personally think less is best.So just curious, when you Xray for puppies, do you run any risks of harming the puppies with the radiation? Is there a best time that is both accurate and more safe?
