Well I ,
We had ours on ten acres, built our own lean-to shelter, grew our own corn, bought our own deworming and vaccines ( don't know if you still can) kept ours barefoot for the most part, unless we planned riding on roads or hard surfaces, so we did our own minor foot work ourselves, had a farrier when needed, floated the teeth on our own. They got hay, out corn, sweetfeed, in winter, extra feed if doing hard trail riding during warmer weather otherwise just a little hay and the pasture. We did have to take the tractor and dusc the feilds to spread the manure, or remove some. We didn't have distruction, maybe because we didn't keep them stalled.
Appaloosa were our easy keepers, my Arabian more work, had delicate thin skin, more sensitive to bugs, needed more support in winter. Appaloosa ( not mixed with a ton of quarter horse) and mustang really are the most hardy. Some breeds are more tendar fiited and thinner skinned.
My neighbors bred American Saddlebred and they are my favorite to ride and temperament, but not the inbred hyped up show horses! They were prone to more hoof issues and lameness than my Apps.
My Apps had more endurance by 10×, somewhat onery , can and did kill some stray dogs ( but fine with ours) healthy sturdy, easier keepers. I think they might appeal to your lifestyle choices. My mare Outlaw was a white leopard, never sick a day in her life hooves of iron, if you are a jerk shed knock you off ,if you were a babe she would walk like a kitten, try to keep you on her back and if the kid fell off she be careful to stop and not step on them. Regular people she stepped on any time you were standing by her and not paying attention. She was a heck of a horse!
PS. Fat rummped quarter horses, never met or rode one I liked. The old school type like the roping ones not so bad, I got to ride and old-school type crossed with thoroughbred in a show once, who was pure magic! At the end of the show they hav a balloon race, you have balloon taped to you back, and you have a dart to pop everyone else's balloon. It's dark by then so they have the lights on, an obstacle course and a hundred people on horseback malee! The owner let me ride him in that. We flew! We read each other's minds, we are like silk flowing through lumbering oxen! It came down to me and a cowboy. We put on such a show, the crowd was wild! Then he let me win, I was so mad! But I was 16, the crowd was on my side, my mom said he had to let me win, or be eaten alive!
Thank you for stirring up old memories and letting me share ( if you read this far bless you!)
