Hi, I've had my sheep's legs xrayed. They are pet sheep. The vet brought out a portable x Ray machine and it was fine for the sheep. Didn't really show anything much, thought it could be arthritis so put her on Rimadyl which worked quite well. Hope your girl is improving now. Just one other thing, one of my ewes was very lame and there was nothing obvious, tried all sorts, but then put a poultice on her hoof and it turned out to be a very deep seated abscess. Hope you get it sorted out.
