I've started noticing that my horse has started to hit his heels / pasterns ( you hear a loud clicking/clapping-like noise) when he moves, mostly during transitions or at the trot. Does this indicate anything? Stiffness possibly? I'm sure repeated hitting will cause some sort of damage to his heel, are there boots you can purchase that protect his heels?
Sorry if this is the wrong section, I was torn between riding, equipment, and here..hopefully I made the right choice!
