My avatar is "my" beastie -- he's not actually mine but my friend lets me pretend he is.
That would be William (always William, never Will or Bill), aka Big Irish Beastie. He is a 17.3, 1500 pound Irish Sport Horse with a personality to match his size. He is smarter than any other horse I have ever met. Let's see:
-- When he couldn't reach the food pan in the back of my friend's car on account of the fence that he was leaning over, he grabbed the towel sitting under the food and starting scrunching the towel (and the food with it) towards him ever so slowly with his lips . . .
-- If he's bored with you and your plans, he will *sneak* away. If he just tries to make a dash for it, you will find out, so he moves one foot at a time, very slowly. It takes you a while to realize that your horse is 10 feet farther away from the car than he was when you started (we tack up in the field where he lives). Then, when he is 10 feet away from the car, as soon as you bend over to pick up the saddle or another brush, he will turn around and walk away.
-- He must remember on some level that Carbocaine stings (see later paragraph about lameness issues), because if he sees you with a needle, he will not let you go near his legs until he is completely convinced that you have gotten rid of the needle and moved on to some other activity. He stands like a doll for IM and IV injections in his neck.
-- Once, when he was having a drifting issue in the middle of a combination, my friend's instructor put a pole on the landing side of the fence just to the left of center and perpendicular to the fence such that if he drifted left he would land on the pole. Well, he didn't see the pole until midair, whereupon he looked down, saw the pole, and spread his legs apart, landing with his left legs on the left side of the pole and his right legs on the right side of the pole. I kid you not.
Alas, William, who was raised in Ireland as a foxhunter and then imported to the U.S. and sold as an eventer, is not destined to ever return to that level of athleticism again. He tends to have "broken back" angles and has had numerous collateral and sesamoidean ligament injuries. While those are fixed now, he has some degree of coffin joint arthritis and will probably never go above Novice, assuming he even stays sound enough to go Novice.
He is only 14. He will always be my buddy, though. I never got a pony as a kid, so he is my "pony" that I can hop on bareback (with help from a tall fence) and wander around in the woods with.
