Should I try to trim her hooves myself? I'm in a dilemma!

I believe she was showing how to rasp down a flare without using nippers. It was just that her demo horse didn't have a flare to show it on. I don't think she does that for regular maintenance.

Interesting, I understand the concept but every farrier I have ever known has rasped just a little on the hoof wall to make it look nice and then about 50% of those will put like hoof oil on.
