I got my Piant last year and looked at him when he was finnishing shedding out and he was pretty and DARK black loved it, then after a few months faded pretty badly :( he doesnt like blankets and I worry that if he fights with my moms horse he could mess it up. So I just feed flax so its shinny! Bit he's a pretty black overo paint with some tan/brown/bleach going on... its not that bad it looks kind of cool in the sun light.. I might be trying a supplement next year.
What about the horse shampoo that darkends darks?
