Farrier came today. He thought the heels were more "worn" as opposed to low, and not underrun. He also said the toe was far too long and will work to shorten the toe. He only trimmed about half of what he felt needs to come back as he did not want him to be sore. He did not recommend shoes at this point, so we are keeping him barefoot.
The farrier previous owner used was on the list mentioned here, but to his defense, I don't believe she was having the horse trimmed on any kind of regular basis. Could have caused problems?
On a more concerning note, he (the farrier) offhandedly mentioned possible high ringbone and/or arthritis in right rear?? He did no seem concerned and thought finding his balance would make a huge difference. I have started reading other posts here and ringbone sounds pretty serious? Maybe I should start some kind of joint supplement at the very least??
