My dog has had a slight limp for awhile now. I took him to the vet a couple months ago because it seemed to be getting worse. They did x-rays and it was very expensive, yet they didn't see anything wrong with his leg. It is obvious something is wrong or else he wouldn't be limping around. They gave him pain meds and anti-inflammatory meds and I gave that to him until he stopped limping. Now he is limping again and it seems to be really bad because he won't even put weight on his leg. I don't know what to do and I don't want to take him to the vet again when I just spent a ton of money doing that and they found nothing. He doesn't seem to be in any pain when I touch his leg, but I did give him his meds today just in case he was. Does anyone know how to handle this situation?
