Barefoot trimming is amazing. My mare travels better than she ever did with shoes. I have studied with a farrier so I could do my own horses. My knowledge is pretty much limited to keeping my 3 horses and my moms 2 traveling the trails. I wouldn't ever go back to waiting around for the farrier...
I was forced into doing my own trimming (my little girl "takes aim" at farriers). I went into it kicking and screaming, but then it became an obsession. Mainly because initially I had no idea what I was doing (not that I am an expert now) and was so worried about making a mistake. It amazed me how "interesting" I found something I absolutely did NOT want to learn!!!
Now it is pedi time for my horses. I found all us were much more relaxed now that I am not getting irritated waiting for a farrier who was always late and rude and my horses like the extra attention from me. It is just a better experience now.
I have two out of three horses barefoot and LOVE IT!
It started with my Gaited gelding having lameness issues of sheered and contracted heels. Too many years of too small of shoes and placement being too far back with ROLLING the toe so bad that the horse looked like he was standing on balls instead of feet.
I finally had enough and took the plunge to pull the shoes off him and put him into easyboot epics. This horse has never traveled as well as he does now or stand square as he does now being barefoot.
I will trim them up with the grinder every so often in between trims.
As for our QH mare, she has her front shoes only (because she's a princess LOL) and bare on the hinds and does well.
Our other gaited horse that we acquired in Sept. 2012 wasn't used for a few years and had no shoes so we kept him that way and purchased more epics for him for the trail. Again he travels perfectly barefoot and with boots.
