My horse has thin soles, and I have fought with farriers to keep them from paring his soles out....my present farrier does not do this thank heavens. I have three other memberss of my horse's family with similar feet....lots of wall, but thin soles. I have read about Durasole, and various other foot treatments....I am presently using Venus Turpentine because I had it already. A highly respected pro suggested I have his coffin joints injected. I wondered if one were to take this route with this problem, how often is it safe to have this done? this pro indicated that this was a common treatment for show horses on the AA circuit. any information would be appreciated.
