Currently I am helping to train a three year old gelding. At the moment he doesn't lead the best. He understands to walk with people but he likes to fall behind, which when we're walking through a field with a lot of other horses that just crowd around. The worst bit he doesn't understand if you tap him with the lead rope. The only way I have found that he moves (when there is no other horse leading the way) is to use leg when sitting on him. We've been trying to encourage him to trot but unless another horse is in front of him (or he's being lunged) he doesn't seem to move.
Do any of you have any tips?
