Years ago, we did the same thing for my Appaloosa gelding. It looked weird and scary at first, but it didn't affect him at all. We did a few more frequent trims as the hash-line neared the tip of his toe, mainly just to keep it from flaking (Appy hooves ... zheesh!) but it worked like a charm!Mine are both super fuzzy! In the cutest of ways.
My farrier did an interesting job on my mare 3 weeks ago - she's had a slight hoof crack for several months, that normally should have grown out, especially since she is always shod so there's no stress on her hoof to make the crack bigger. But her crack instead of growing out, kept traveling up the hoof wall - just a slight crack, not enough to make her unsound, but frustrating because we couldn't get it to grow out.
The farrier thought, and I agree, the crack keeps persisting up her hoof wall because bacteria is getting in there and preventing healthy hoof growth. It's not white-line disease, but if we did nothing, it would progress into white-line disease.
So our farrier took his rasp and filed a line into the hoof wall above the crack, pretty deeply in to where the crack started, but carefully not into the lamina. It looked pretty shocking! But amazingly it is not at all uncomfortable for her at all, and she is still 100% sound. Every day I clean her hoof really well, then squirt a bacteria-killer (Dura-sole) into the exposed hole, until it runs out of the bottom.
So far, the crack has stayed below the shocking line, and 3 weeks later looks like it's starting to finally grow out. Can't wait to see what it looks like in 6 more weeks!
