Our horse came to us with a mild case of common stringhalt. Occasionally, he would lift his left hind leg about 1 ft. And stamp down on it. A jumper converted to hunter jumper, he would rarely exhibit this behavior with my daughter in the saddle. After a record breaking summer rainfall here in Maine, he developed scratches on that leg.He began to show more exaggerated leg lifting.We treated the scatches and it improved, but the leg lifting worsened. He would lift it very high and lose his balance hopping on his right leg to regain his balance. It was saddening to watch. Our vet said his stringhalt was very advanced and only surgery could possibly help and my daughter could not safely ride him again. She called a surgeon who asked her to perform a block to the peroneal and tibial nerves. If the symptoms were mitigated,there is a chance the surgery would be successful. There was no change. He was very smooth over the fences and he will never jump again. I don't recommend you purchase that horse . .
