I usually don't blanket, because most of mine are really fuzzy, but the mare and foal get really cold, really easy, so it's more comfortable for them and considerably more economical for me to blanket instead of having them sit around and shiver off calories. I don't have a barn (do have shelter) or they'd come in at night. The thing I didn't really register about the mare's blanket was the front fastener, because when I do blanket it's the cheap ones that just have the buckle in front instead of a snap. However, this one came from her previous owner and I didn't know it's quirks yet (I do now, though
PaintHorseMares-- I do know that halters can get hung up on all kinds of random things, which is why I don't turn out in halters, nor do I turn my horses out with a bunch of random crap. I've been around horses long enough not to be surprised that the clip got stuck on something, but I was surprised that it got stuck on another horse. I'm also wondering what would have happened if I hadn't been around, because a horse can pull against an inanimate object without hurting it and the object or the blanket will probably break. However, I'm not sure, in this scenario, what would have happened to my foal.
