Several Standardbred trainers have told me that when a vet cannot find what is wrong with their horses, the vet will suggest putting them on Baycox. I recently had two vets tell me to try my 3-year-old trotter on Baycox. They had gone all over him and thought that might help him where nothing else has. He has had no tests, blood or spinal. So my question is: What else can this drug do to help a horse? Does it treat other things, not just EPM?
