Horse Brushes that do double duty? Nail a few old horse brushes (the bristly ones) to the sides of the stall so your horses can rub against them to get at those annoying itches.
Are you shining bits, stirrups, and buckles? Toothpaste is wonderful for cleaning white stirrup pads and shining silver bits, stirrups, buckles, buttons on your tack. Toothpaste will make your horses gleam!
Looking for some Horse Stall Toys? Clean out a milk bottle well and fill with molasses for your favorite equine. Poke a few small holes in it and tie it to a tree or rafter and watch your horse spend hours licking the jug to get the molasses out.
