Thank you so much for you nice answers! And for the link, Romy, I hadn't found it before, so it was very helpful.
I already showed him the idea of putting things into a bucket. And I think he liked it, so we will continue this
And I also noted other things which I want to introduce to him step by step. I like the idea of letting him put his frontleg on different things, playing with poles and cones... and I very much like the idea of the body target, that sounds great!
Marina, do your hoses paint with a brush and waterpaint or what did you use?
And I like the idea of TTouches as welcome and goodbye rituals. I guess I will propose it to him.
The walking-part is getting more difficult though. Yesterday he saw a horse 200m away from us, when i let him graze. He got so exited it was very difficult to keep him from running towards the horse. I had to keep him quite tight, even if normaly I don't use the rope at all, as he listens very well on my body-language. But yesterday I couldn't reach him at all. I went with him towards the other horse. Some steps, then halt, pause and then another few steps. But we were both very exited, and I had to keep him very strong on the halter
Later, as we had reached the other horse he relaxed again. When we moved on, letting the other grazing horse behind us, he got a little exited again, but our normal proceeding worked out his time: by asking him to halt, look and wait he relaxed again. And so did I. No need to pull on the halter, just letting him the time he needed, and then we could go on easily, with a long, loose rope.
How do you react in situations your horse is too exited to listen to you? I really would like to find a solution other than getting tense. Even in cases our normal ritual doesn't work.
All the best,
Anna
