Maybe this is more an english thing... I wasn't sure so I'm posting it here.
So today I went out and I decided to mix things up and try ground driving Lacey. Well, either she's never done that before or I was totally messing up.
I had her in a surcingle (I think that's what it's called...the thing that you can lunge in side reins with?) and her normal bridle (the one with a bit, a french-link snaffle, I figured that ground driving probably wasn't a bitless maneuver) with the lunge lines basically exactly like they are in this picture:
I was not using a whip becuase Lacey gets pretty antsy with one around and even though she's finally ok with using one for lunging, I figured it might be safest to not use one ground driving just yet.
But anyway, I could not for the life of me get her going straight. She seemed to have to be able to see me because whenever I ended up behind her she'd start turning more dramatically so she could see me out of one of her eyes. She was perfectly happy going in a large circle and switching directions, stopping and backing up but she would not go straight. I would get her to go one step straight, then she'd start turning again. She also was having issues making slight turns, she'd automatically interpret any shift on the lines as a request to switch directions.
Any ideas? She seemed to just be confused, not unwilling to try to figure out whats going on.
She was also responding GREAT to my voice commands for walk, stop and back. I usually only use those, except for stop, when I'm lunging her to it was great to see her connecting those.
