I remember seeing that! It was SO COOL.

Some people think that a horse is only as good as it's pedigree.... ugh. They aren't wrong - knowing about a horse's lineage is especially helpful when you're breeding, But if you don't plan on breeding, their great-great-grandsire doesn't matter half as much. Nor can their bloodline affect the temperament of the foals they'd have - cuz they wouldn't have any!
But can you imagine how tough a mustang MULE would be......
He can open the gates now.

He takes the hose out of the trough and throws it around.
He opens the gate WITH HIS TEETH
He kicks the bathtub-feeder out of his way so he can make sure there isn't any hay underneath
And he takes the buckets off the fence and plays with them.
I'm so screwed
They might eventually, but since QHs are so popular and there are sooooo many of them, I doubt it'll ever become a serious issue.
XD I said the same thing once
Then we got horses. XD

But now we're set up for them and Dad keeps getting freebies (like Smoke XD) and we can't seem to get away from them.
