i do not realy know how you train it. But i had it yesterday by accident.
It was a windy day and there was a white sack moving around the farm. My horse was spooky, so i decided to go after the sack and no riding.
I know it would take a lot of time, but i saw a great opportunity.
So i started, i we passed the sack, i was between the horse and the sack, so no problem. I go every time that we passed the sack a bit more to the sack. We were very close, suddely the wind came in the sack and it moves...woeshh you hear..my horse ran away..#$* he turned his neck and i could not hold him..so he was realy gone...i go and get him and try it again...we reach the sack. I let see him that it was no problem, i can stand on it, pick it up, and lay down again. He looks interested, but scarry..i ask him to go with his nose to the sack. (he know this game) and yes a quick touch and a YES treed and move on.
When we got away from the sack the wind was there again. He run away for the second time and did the same with his neck..jee..too late again
So he run away..
At the end of the parking place there is a storage of hay, it is covered by plastic. One of those plastics was laying on the ground, so i saw a new project..
I go with my horse to the plastics and i walked on it. Just a few steps. I sit down and ask my horse to come to me with his nose, so i new he had to do a little step forward to reach me, but he was scared and did not move.
But his nose came very slowly towards me...
little by little more, suddenly he was totaly steched out..i did not know what i saw..i had try it several times in the arena, but nothing works. But now he did it..because he does not want to stand on the plastic...but the treed he likes very much... So i give him a yes and a treed of course.
Stand up and walked to him. And do it again..and yes he did it again...
It was not the point that i wanna reach at that time but i was happy that i had found something to let him do this kind of movements.
Then i go stand next to him and join him together to the plastic and touch it with his nose..so he did finaly..so i had two things at the same time that day. Although it was not planned at all.
But i was happy and he too after all.
I think it is not the correct way...but it worked for me yesterday. Next time i will try it again in the arena without the plastic
