That is the question. I have a BLM mustang & I read that mustangs do not need shoes (or blankets, for that matter). But I was wondering how much truth there is to that. Her turn-out area is mostly sand with some large rocks (think creek bed) & we mostly trail ride with some asphalt in town and some rocky creek beds. Diva (my QH) does much better shod than not, but Brandi (the mustang) seems fine barefoot.
I do pick out all my horses feet regularly whether they are being ridden or not & regardless of whether or not they get shoes, they get trimmed on a regular basis.
