I have nothing against the Pete Ramey trim guidelines. They take a lot longer to get the foot back in shaoe than the ELPO guidelines, IMO.
And he makes it a lot more complicated than it has to be. But because they are so conservative they are safe to use for those who are a bit less experienced in trimming . You are lucky to find ANYONE who will work on a draft, too. Many farriers and trimmers will not do them at all .
Yes, it is EXTREMELY hard to find someone that is not only strong enough to do my mare's feet, but patient enough. She has been man handled in the past, including my last farrier and she is sensitive to someone else handling her feet. She does much better for me. AND, if she is having a bad day, or needs a rest, I can always finish later. AND, I am always there to touch up a trim frequently and fix problems as I go. It is win, win for me even though it is very hard work.
But, I am still wondering about her lateral side of her hoof. Is the white line stretched or just wide? Her hoof wall was taken waaaaaaaay back almost to the water line (the white ring), but then there is still the white line (darker ring) before the sole that is very wide......or am I wrong?
