See, I don't understand this. Why would I care about which feet are being placed where rather than allowing those feet to go the proper direction? WHY would I want to confuse a horse with one foot, two feet, three feet, four feet? For some reason, Dr. Seuss comes to mind. To me, this is needless piddling. If I want him to walk in, I want him to walk in…not hesitate or worry about which foot I want where. ie. TODAY we're only putting one foot on, now two, etc. Why not just allow them walk in when you ask them too. Isn't that what you really want? What am I missing?
Did you read my link? If not, do that first. Might explain things better. I think you are just missing the "big picture" and the actual purpose behind one foot in, one foot out.
Yes, your ultimate goal is to get the horse onto the trailer. But I've seen it happen frequently where horses (and owners) don't know what to do once you get the horse all the way in the trailer. Or don't understand why they have problems once the horse is loaded.Or why the horse walked right on the trailer yesterday but now today they don't.
If you've not done your homework, you are going to run into issues like the ones we've been talking about (horse pulls back in the trailer, panics when the butt bar is put on, backs out before you can close the dividier, refusing to back out, etc etc).
The concept is MORE than just one foot in one foot out. You are teaching the horse BODY CONTROL. That means I can move their shoulders wherever and whenever I want. I can move the ribcage. Hindquarters. Etc. If I have control over each foot and where each foot is going, I can do anything with my horse;
including load them onto a trailer. I have their attention
and their respect
when I can control each foot, and each body part.
It's that body control that you are seeking for fixing ground work problems, which is what trailer loading is. When you go through all those steps to have that
good of control of your horse on the ground, trailer loading becomes a piece of cake.
