Yep...they make 'em for horses.
This spring, (BC...before crutches),
Buck was ordered a fancy new pair, in lieu of metal horseshoes.
Buck came to us with compromised hooves, many years ago.
The hoof will reveal a lifetime of nutrition, or lack thereof.
We felt, in Buck's case, a boot of this nature would serve him well.
Less invasive, and worn only when ridden.
