Every single time I see them. I don't ride that often so how else would I spend time with them? Also, I love brushing. It's just so relaxing and satisfying to me to brush them. Dixie just tolerates it but Apollo loves it and will stand for hours at a time. He also moves around based on where he wants you to brush. Dixies mane needs to be brushed out every grooming session because it's so long, it'll form dreadlocks otherwise. I don't really mess with their tails unless I'm really bored. I mostly curry and use the hard brush. If I want to be extra thorough I'll use the soft brush to get them really shiny but I don't do that too often. So they get brushed very often, and I've received tons of compliments on how shiny and smooth they are. Maybe they don't need it, but I enjoy it and Apollo enjoys it (Dixie just has to suck it up lol) so why not? I don't pick hooves that often. If I notice something is off of course I'll look at the hoof and pick it out, but that's never happened. But I rarely do pick the horses are fine with hooves being picked out but I feel like they don't really need to be. They're not shod and it doesn't rain that often here, and when it does they're standing in grass, not tons of mud, and it dries out pretty quickly. I've never had a farrier say anything about it, as a matter of fact I've always been told that their hooves are in great condition and to "keep it up." If they were shod or frequently in muddy conditions I would pick often.
