That’s what horseshoes are for. A hoof is a giant finger nail. There are only nerves near the roots. You don’t need to wrap a giant finger nail in leather. They evolved to handles temperature extremes just like how an alaskan wolf doesn’t need little leather booties to live their lives in the snow 24/7.
The lady was mostly doing it to make herself feel better because again, it’s a case of anthropomorphization. I’d bet money that if they did some brain scans, they would show zero difference with or without them on.
And no, I’m 33 years old. I’ve been exposed to and have dealt with animals since I was a toddler.
