> But dogs and horses don't have the conceptual ideas of freedom and economy, and they enjoy doing the work they're given (in part because we spent hundreds to thousands of years breeding them to do that).

Horses know they are slaves and don't like it. But they aren't very smart, and like not very smart people, they take petty revenge when the opportunity arises. For example:

1. if you walk behind a work horse, he's likely to kick you

2. if you ride a horse, he'll try to run under a branch to knock you off

3. a horse will take a deep breath and hold it while you cinch a strap over its chest. Then the horse will exhale, and the cowboy will have to cinch it up again. What the savvy cowboy does is pull on the strap until the horse gives up and takes a breath, then cinch it hard

4. to work with horses, you've got to let them know you are in charge and won't take any nonsense from them
