LoL, come on, give me an abstract of the article...it's so long!
J/K, I will read it tomorrow. :) But it sounds from your all's posts like it says what I have always sworn by. I have a TWH, and she's 3 with baby teeth. She was broke when I got her, but I have stopped riding her to work on ground manners and slow things down a bit. She's still growing and doesn't seem to have the maturity level to do a lot of things that are often required of 3 year old horses. She gets a bit "ADD" if we work for more than an hour or so. I figure, why push it? She will live 30-some years, I hope, so we have plenty of time.
I actually had a pointless and silly argument with a person used to working at tracks with Thoroughbreds (NOT saying all, or most, thoroughbred owners push their horses too young - lots of walker owners start their horses too young too, IMO). He wanted to get my horse out and ride her on a whim to "try her out..." whatever that means. I explained to him that she was starting over on ground manners and she had already done her "work" for the day, so I wasn't comfortable with him working her. He said that that was ridiculous, horses can work all day, etc.
LoL, frustrating, needless to say.
