She nearly got the mother of a buster. Tammy died quietly in retirement only a couple of years ago. There are others, many others. I've seen some real nasty ones like a Blood stallion up at Inverell that would kill any human that got into the yard with him, and some naughty little ponies that would sidle quietly up to you, lop their ears and boot the tripe out of you. I've even been silly enough to let a zebra bite me on the foot outside a circus tent once.
Horses have as many characters, dispositions and moods as any other animal, including humans.
I have had a quiet sixteen hand horse called Skipper stand on my fingers when I was shoeing him. I was too stupid to pull my hand away when he decided to ease the other leg he was standing on and stand on the one I was working on. He picked the other leg up and no matter what I did, he would not shift. Bev had to rescue me by leading him forward off me hand after hearing my screams. Thank goodness the dirt was soft.
