He only pulls them when he's being a twit or if we're riding through really mushy territory. When he pulls them in the paddock or the pasture it's either in the spring when it's a swamp (we stopped shoeing in the spring last year because of this) or when he is tearing around bucking like a lunatic in the soft ground.
If he pulled them just walking/trotting/cantering around on good ground I would definitely look at a hoof issue, but that's not the case. It's just in the mushy ground, idiot horse circumstances. Unfortunately I have a lot of mushy ground and he's kind of an idiot sometimes in the pasture and under saddle.
He's usually only shod June, July, Aug, Sept and we go about 6-8 weeks between shoeing, so it's 3, maybe 4 times a year, so when he pulls a shoe twice in a season it's significant for me financially, even if it's not "that" often in the grand scheme of things. Especially because of course he doesn't wait to pull them right when they need to be reset, oh no, he has to do it at the beginning.
I'll look into the venice turpentine and the durasole and talk to my farrier about it. Thank you for your boot recommendations!
