Xrays should not be done b4 the 45th day of pregnancy bc the radiation can be harmful to the puppies. Xrays should be done after 46-47 days bc the bones of the puppies will be calcified & you can see them (head shape & spine) on xray. Xrays 3-4 days b4 birth is best, the vet can determine if the momma can pass the puppies on her own or if a c-section needs to be set up. |
