Oh but you don't know my horses. Ok, my colt probably wouldn't do anything, but my older horse is a True Stallion. And you know what stallions do when their herd is attacked? They protect them
(watch Hidalgo, the scene where he kills the leopard, that's what stallions do. Except mine is more fierce)

I can try getting a picture of my horse trying to murder dogs if you want, he chases them like a maniac And no doubt he weighs just a BIT more than your little poodle!
