I've done just standard pasture trims on my own horses for the past ten years until I got Henny. I went through 3 farriers before finding my current one who is GREAT. Lately I've been rasping Henny's feet every week, and he'll come check on them every 3 weeks or so to make sure I'm doing well. I actually have the opportunity to do an apprenticeship kinda thing with him, though I'm so limited on when I can work with him due to my work schedule. I've only worked with him three times so far but I've learned a lot already.
I don't think any of the horses at my barn are on a regular trim schedule(excluding the three that are shod) so I think it'd be a good place for me to start. I just need a set of tools first!
