Touch is your best guide for catching early signs of issues that could become problematic if not dealt with early on.
I certainly agree with that! All kinds of bumps and lumps can be detected, some of which if left unattended, could be serious.
Thank you for the tips! I would like to add a very personal opinion too as not only is grooming for the show coat, but also the horse will reveal to the rider just what his treatment is before and after training. A sadistic groom can undermine the best efforts of even the most ardent and empathetic trainer. Good grooms, like good shoers, are a rare commodity these days in a world that seeks to commodify everything. A lot of the servants of the horse world have truly thankless jobs. Praise your groom, and give them a raise!
