The difference between a "natural" trim and a regular trim are based on several things. A lot of farriers (not all) will take the sole off a horse, just as if they were about to put a shoe on. This is the worst thing you can do because the horse probably will be sore because all that calloused sole he worked so hard for is now gone. We have to leave the sole alone. Also, a lot of farriers will not put a "mustang roll" on the toe. The mustang roll will help prevent chipping, cracking, and flarring. It will also start to help the hooves become more concave and not flat. If you go on to Pete Ramey's website you will see pics of how horse's hooves should look like. GORGEOUS feet!! Sometimes farriers leave the hooves too long or the heels too high. A lot of horses will develop the "long toe, under-run heel" syndrome.
