The best horse I ever owned was 1/2 QH 1/2 Arabian. He was a problem horse because he spooked. He was also 4 years old and a first horse for someone, trained by a 'breed prejudice' trainer.
I did everything with Zayn! He was natural with cows (though he always stopped on his front end.. ALWAYS!), loved kids, and was very gentle.
He was very athletic and loved to run! The first few months of riding him I had a hard time making him walk home (we rode on the gravel roads), I noticed that after riding my shoulders and arms were sore, and my sister pointed out that Zayn was always pulling on the halter (we were doing Parelli to some extent), so I decided to work on that. I would ride on a loose rein towards home and as soon as Zayn would break out of a walk, I'd stop him and make him stand until he sighed and relaxed/gave to pressure. After a couple of weeks, I could race against another horse, towards home (we would be several miles out), then ask him to slow down and walk. I could drop my reins on his neck and he'd just keep a nice relaxed walk.
He also ponyed colts really well, after two lessons or so he would take anything from them and not respond. I ponyed this one pony mare once and she hated him. She was biting, trying to strike, and kick him the whole time and he never offered anything back.
I would goof around with him pulling stuff from his saddle horn too. We pulled a lot of firewood logs (5 foot lengths) out of the bush into the open.
He would babysit any one else who rode him. With me he had a big trot and canter, besides of an awfully fun gallop. When my sister rode him, he'd gently jog, carefully canter, and never would actually gallop. It was kinda funny!
I had to sell him because we were moving. The best part was watching guy that bought him interact with Zayn. Zayn normally didn't like men (his 'trainer' wasn't the gentlest, and was scared of him), but he responded and behaved really well for this fellow. He cried the whole way out the driveway and down the road (he wasn't herd bound, and the herd was pastured half a mile from the yard).
If I could, that horse would be mine again!
Now, my sister owns a 3/4 Arabian 1/4 QH gelding and he's a bit of a brat, but not mean. He just hasn't ever had much training. I think with more training he'd be a lot like Zayn was.
So there's my book... But a book isn't complete with out illustrations, so...
I rode him a lot around the pasture just for the fun of it.
Ponying a crazy TB mare. She liked to hurt people and eventually it wasn't worth the risk so she was sold (auction with a note)
His short tail was a special gift from his special pony friend...
He rode equally well in a halter or snaffle
On a ride
Running to me to be caught! He loved it when I gave him a job every day! (bringing in the milk cows)
My sister's gelding, Kid. Here my brother is putting the first ride on him.
My sister riding him this spring.
My suggestion... get one if you can find one! The ones I have known have been worth their weight in gold!
