No offense taken DesertHorseWoman. I know how frustrating it is to see the solution so obviously and provide advice through experience and have it ignored. Incidentally, I didn't ignore it, just didn't know how to execute it. I still don't but it can't hurt to ask. My next lesson is in a week.
I don't know my instructor's take on lunge line training. Maybe she does it for younger kids. Personally, the thought of it makes me a little quesy. I don't really like trotting in circles for long periods of time. I never feel fully on balance.
Our last barn was an indoor round pen and one thing my instructor mentioned is sam doesn't stand up into the corners and turns, which is one reason I lose balance and momentum on the turns. She has a full size indoor arena and outdoor dressage ring. We now have plenty of "straight" and less "turn."
I don't even know how Sam will react to a lunge line and rider and from other forum postings, I don't believe he knows how to lunge. Mainly I just made him trot in a circle and halt on a lunge line. Not do any fancy things.
One reason I think we are having issues is him and the single joint snaffle bit. He is not working at all like a broke horse. I bought a new bit this morning; I went with an eggbutt french link.
If I can keep him from throwing hissy fits while he is working I am sure I can execute this. I pulled the single joint snaffle off his bridle this morning and it has teeth mark divots. Not just scrapes. Actually divots. He wore that bit 2 times.
What a booger.
