One of our horses has gone lame and we have tried everything under the sun to get him healthy again, but he is just not responding well to treatment. Three weeks ago, we found him lying in the pasture with a swollen rear leg. We had the vet come look at him and he was treated for an infection. We kept him in a stall, and wrapped his leg, plus fed him his antibiotics and pain relievers. The symptoms didn't change much for several days. Vet came out again and we had another round of meds, wraps, cold washing and stall time. He got a little better, and we and the vet figured it was a bad case of cellulitis. We put together a round pen in the front yard to keep him in while he healed (flat and even ground), but that didn't hold him too well as he wanted to be with his buddies in the regular pasture. After retrieving him from the neighbors yard, we put him back in with his pals since he seemed to be healing well and putting weight on his hoof again. Unfortunately it didn't last long and now his leg is swollen and leaking serum again. He won't take any meds in grain or treats anymore (He caught on to our sneeky plans) and is three legged lame. We are now three weeks into this and are at wits end. I'm not sure how to help him much more than what we have been, and the vet bills have racked up pretty high. Any suggestions would be helpful.
