Ok, my gelding Ziggy has confused me again. The other day I went out to walk him and he absolutely WOULD NOT walk for me. I used the lead rope to make him go in really tight circles and had to do that for ten minutes before he would walk. And then I had to do it every couple of steps. But as soon as I put the saddle on him, he was a dream to work with. What's up?
Maybe he's one of those horses that really don't like your everyday ground work. I've been working with a horse lately that can be quite aggressive on the ground (because he's dominant and his owner has never really done anything about it) but when you get his mind he prefers riding over ground work. This horse LOVES trails. So maybe your horse has the same attitude (without the aggressivenes!).
Were you trying to lunge him or just hand walk him? What do you do with him under saddle?
Maybe with ground work you could try the Parelli 7 Games. Or set up some obstacles for him to navigate to make ground work more interesting and fun.
Pops is wierd like that, too. I don't have him saddle trained. But he'll be absolutely terrible unless I'm doing something direct with him, such as bending or other things I've taught him. But walking with him is a nightmare. And yet if I give him a clear direction that he's learned a long time ago he's perfect.
I have a boarding stable and work with different horses all the time, it's amazing how easily horses get bad ground manners. One thing I do is use a dressage whip on horses I am having trouble with. Every time they stop, just tap them on the butt. Keep tapping until they take a step, and then reward them. If you keep doing this, they eventually walk willingly. It's the same for a horse that tries to walk ahead of you, just tap them on the shoulder.
If the horse wont move when you cluck and pull, back her up aggressively for as long as you can (all the way accross the arena, around the round pen, etc) repeat this until they decide to go forward instead of having to go backwards again. Make walking forward a good release and backing the punishment...FOR NOW, not the case for everything
Lol my horse ziggy too dose that like all the live long time xD but wen I put the tack on her she dose what ever I ask her to do with ease but I just think her problem is that she has a baby in her belly?
