Thanks for the great responses everyone. Now, need to think how to get through it all.
1) I walk with him sometimes, I tend to shorten the rope then, so I keep the same circle, but I can control him a little better, encourage him or so. As he is a big, young, and a bit stiff horse, I do not want to ask him to go in small circles. I do have a 3m (i guess around 10 ft) rope, but that is WAY too short to do any work in atm, and have the end for me to correct him with.
2) When wiggling the rope, he does flick his ear to me or something, and I try not to stop before he responds, but my arms get tired of it. And when I try to pull him in he either starts running like mad or pulls me out of place, and he is hard to hold when he starts pulling.. But we are working on it. I was actually thinking about work on the 3 m line to keep him a bit more under control..
3) Angling myself to his rear might be hard sometimes, especially on right hand circle - he does not see me (right eye is gone), I have to be careful to send him on that side, as he quite often moves faster than asked. Just because he is confused with the sounds he hears, so I try to be extra subtle there.. But will try with the other side.. He does quite often actually get his head inwards to see me better, flicks his ears towards me and gives me this high eye, staring down at me
4) I am working hard with space boundaries - I like him coming up to me for hugs in the pasture, on the lunge he usually waits to be invited in, and never brushes on me, he comes about 3 ft away from me and waits for my reaction. There I usually touch him, tell him he is a good boy, and only sometimes go one step closer, hug his head and send him back out..
5) I am giving him vocal commands - without those we cannot lunge due to one blind side. Every time I am shaking the rope, he also hears a "trrr" which is meant for slow down. Must confess that he pissed me off sometimes and I had to reset myself, to calm down and breathe calm.
6) I am trying to be more clear with my arms, body signals when changing directions, but I guess I am used to the old way. Teddy turns when you ask him to slow to walk, switch hands for whip and lunge line, say "turn" and he goes... Grand is learning.
7) I really wish I had a round pen, but I cannot make one just now. Then it would be a lot easier to change directions etc. When he starts to take off like in the first video, it is very hard. And mind you, he is on 24/7 pasture, he runs with his buddy when ever they feel like it. When on the lunge he still feels like he needs to run... Ok, his energy feed might be a little high for his work amount, but it's there to gain weight and we do not have access to rice bran, or beat pulp or stuff like that.
8) I do not feel very comfortable for him to start trotting and cantering immediately when on the lunge because, we are not there to just bolt, the ground is not the best, he did have 2 legs injured this summer (left fore muscle near the cannon bone, left hind kicked, stifle was swollen). He seems sound, I am counting the left side weird due to the ground, as he moves differently on both sides. I am sure that has to do with the eye..
Overall he has had about 3 lunges since his injury, then it was 2 months off any work, just whatever he did himself being outside (together with the vet decided it is not possible to stall him, as he will go crazy, risk re-injury after returning him on the field, and even a smaller paddock next to his buddy might mean he slips more trying to reach him - but he healed fine with moving around 24/7)
Before that - he has started basics of lunge work this june. This is as far as we have gotten since basically mid june with lots of days off in between (and August, September off), as he is young, was never worked, his feet were horrible, but we had to fix his manners. So ye, I am sad I do not have videos of the first sessions.
I am very grateful for your input, and will sure try, and then try to film some more so that we can talk some more :) I have learnt my ways of training horses from a few trainers that have been around me, and of course on this side of the world the methods are a bit different, but if I manage to correct myself and see difference in the horse, I always adapt the method. I always change the way I work when I see something works better for one or the other horse.
