My boys don't wear blankets, first because I believe if horses were to wear clothing they'd have been born wearing it but instead got a nice fur coat. Second, one horse seems to feel anything the other is wearing ie bareback pad, saddle pad and saddle is fair game to pull on. A blanket would be in shreds in no time.
Yep I agree, most of the time horses don't need them but there are days certain horses of mine will shiver. I don't like that....makes me feel like a bad mommy. So, blankies it is however; none of mine are destructive with blankets so I don't feel like I'm wasting $ on them.
