I find it interesting that certain animal rights extremists (or radical "horse trainers") feel that riding horses, or even keeping them at all, is somehow "enslaving" them. They should all be set free, right?
Mkay. Let me explain something.
Domestic horses are, for the most part, the farthest thing from slaves as any creature can get. In fact, most horse owners will tell you that the horses are the ones cracking the whip.
Dogs have masters. Horses have staff.
Have you ever seen a horse prepare his own meal? And when's the last time you saw a horse clean up after himself? That's what we're for. We are their personal cooks, maids, beauticians, fitness trainers, and body guards.
Assuming they have decent owners, which is the case more often than not, horses never have a care in the world. They're generally a lot happier and healthier living with people than they are out in the wild, taking their chances with the bears and mountain lions.
I don't know, I think I'd rather be a pampered pet than lunch for a large carnivorous mammal.
