Bubba13 is correct! If they are digital x rays the vet should be able to e mail them to your new vet or put them on a disk for you. They are stored on a hard drive. He may not be able to print them out but there are other ways to acess them!
You should look into barefoot trimming for your horse. It may take a few trimmings for your horse to become more comfortable but going barefoot promotes better circulation. Do not just take off the shoes and call it good,
Look for a certified barefoot trimmer that specializes in hoof problems. Barefoot is not for every horse but if the farriers and vets are telling you there are no other options it could be worth your time to check it out. My gelding was shod when I first got him and he had several issues with his feet and lameness. We are 8 months into barefoot and I can ride him over any surface, his lameness issues are comepletely gone and he is happy!
Hope that helps!
