Daryle watches as farrier JR Myers trims Dominique’s hoofs with a rasp (file) and knife! Trimming hooves is an art and should only be done by farriers who balance the hooves and look for any problems. This should be done every 4-8 weeks depending on the horse. Dominique’s hoof trimming is similar to you getting your nails clipped. The last picture gives you an idea of just how small his hooves are!
