My bitch is 52 day post breeding..is is safe to get her an x-ray? This was an opps breeding on an older bitch. I don't think she is pg but need to know if she might be having one or two..TIA

Give your vet a call and ask. :) They'll be the ones to do it anyways. I did my girl on day 58 to get a count, but I knew she was full of pups.
