I agree with the idea of redirecting energy and attention, not just with pits. But IMO the idea of dominance should never, ever be coupled with fear. It should be because the pup wants to please you, get your praise, know he's doing a good job. I'm lucky to have a wonderful dog, and he knows I'm alpha, but it's not like I have to keep asserting my fearful presence: when I say leave it, he leaves it, and then he gets his praise or treat.
Neighbor has rescue pits, love 'em all. Their energy and exuberance can be like trying to put 10 ounces of water into an 8 ounce cup, ya know? We sometimes walk them or take care of them if she's away, and the big boy has a man-crush on me. But again, he's pretty good with me because he sees me as alpha, very few problems.
Another neighbor has a pretty young female pit. Still jumps up a lot. Caught me by surprise the other day and whonked my right on the chin with that cinderblock skull of hers, but luckily I can take a punch.
Since we became dog people, I'm respectful of pits, cautious with ones I don't know, but not afraid of them. The other year there was one loose in the neighborhood I didn't know and thought nothing of going after it with a leash - she had a collar on, and luckily I got her and returned her and another dog that was loose to the rightful owner. Some folks would see a pit and just stay indoors.
