Loved that guy at horseproblems.com ! He said this is not a case for natural horsemanship. Since Jarred is the lead horse in his little herd. Its going to take more than just getting a bond with him. I know My husband nor I can do the touchy feely loving on Fras (the lead mare) that I can do with Vida. He has to be in control of her all the time. Don't get me wrong she is a great horse but like Jarred if she is given even the least hint of any weakness she will take advantage. She went through a phase when every time I walked into the lot she would swing her butt to me (and she didn't want it scratched) I hate to say it but I started playing fullback and rushing her to the point of almost knocking her over. I'm a big farm gal and I know your fairly small so this won't work for you but you get the idea.
My point being, you may have to take a stronger hand with Jarred. At least until you get his respect.
You know how to do it, I think you are just being too timid. You want him to like you, but what you really need to be concentrating on is having him not kill you. Get big, be mean And most of all don't get hurt.
Note to other posters this is just my opinion. Please don't get on me about being mean
