I am an hour East drive-time from Jackson. For all of my big horsey-problems, I go to Lewisburg Animal Clinic (which is east of Columbia). Dr. Victor Wakefield is one of the vets there, he took 8 years of equine-veterinary and he is wonderful. I have been burned by less knowledgeable vets, but have never made a mistake when going to his clinic or at least giving them a call for help! Their ph: is 931-359-5945 just in case you're interested in calling and asking some questions. Dr. Wakefield knows his job.
