The Carrot vs the Stick (from Horse and Rider)
Punishment as a training tool "should become obsolete," says clinician John Lyons. "It's unnecessary and counter-productive... When he isn't getting somethign you're trying to teach him, he's already unhappy. Punishing him at this point is backward thinking, and just causes anxiety...
"Think of it another way: If your boss only yelled at you whenever you made a mistake, and never praised you for doing something correctly, pretty soon you wouldn't want to go to work at all.
"It's the same for your horse."

Me: Okay, what do YOU think? Frankly after my
alpha mare episode, I'm a believer in a little stick - not punishment in the old cowboy sense, but certainly some attitude... If it's all carrots, it just doesn't seem to work...
Canyon (interrupting): Actually you just aren't using enough carrots.
Me: oh give me a break.
Lily: He's absolutely right. More carrots.
Canyon: I'm pretty sure you can get them in bulk.
Lily: And cookies. I'm good with cookies too.
Me: Cut it OUT! Back to the round pen!
