I finally read the stats on horse hoof wall thickness and felt stupid

Was looking up a lameness case last week and found a study saying the average hoof wall is only 6-8mm thick. I've been trimming way too deep on some horses for years without realizing it. Any other farriers here check your angles against those numbers?

Hold up, I see it a little different. Those numbers are averages and don't account for breed, terrain, or individual horse variation. I've seen plenty of sound horses with walls over 10mm that needed that extra depth for support.

You're spot on about breed and terrain mattering way more than a hard number. I've got a Rocky Mountain horse that's been barefoot for years and his walls sit closer to 12mm because he's on sharp shale and granite chips every day - anything thinner and he'd be sore in a week. Adjusting trim frequency (like every 4 weeks instead of 6) makes a huge difference too, especially if you're dealing with wet/dry cycles that crack those thicker walls. Have you tried a mustang roll on those heavy-footed horses? It saved me from doing extra hoof packing on one mare who kept chipping out to the white line.

...and honestly I think we're all missing something pretty big here. Nobody's talked about how a horse's age changes everything. I've got a 23 year old draft cross whose walls are way thinner than they were ten years ago, like 8mm now, and he's perfectly sound on gravel. But a young horse going through growth spurts? Their hoof walls can change thickness by a couple millimeters in just a few months just from how fast the horn is growing out. I had a 4 year old whose walls went from 12mm to 16mm over one summer when I switched him to a higher protein feed and more turn out time. Trimming by the calendar instead of watching how the foot's actually changing is asking for trouble.
