Beautiful, healthy hooves
Here are some photos of a Rocky Mountain Horse that I have been trimming for a little over a year. He has fantastic feet with great concavity.
The photos are of his front left hoof and show a lovely self-exfoliated sole (current ground conditions are snow and ice so everything on the bottom of the hoof has been polished naturally by the ground).
He has a nice wide frog and a well developed digital cushion.
How I wish all horses had hooves like Whistler!
