This horse struggled with 2 years of lameness. He started out in metal shoes, out of shoes, then plastic shoes, then barefoot. He went through 4 different farriers and still abscessing and lame.
His owner found me online and signed up for mark ups. I taught her how to trim. I showed her why he was lame and how we would resolve it. Like most horses he was over trimmed in the heels. When you lower the heel to the widest part of the frog, you must then remove bar height and sole depth. This is why these horses just keep abscessing.
She is now a certified trimmer and one of my best trimmers.
