I'm not sure if this is "a thing" but it's been working super well for Lacey and I, so I figured I would share and maybe it would benefit someone, or something...
Lacey is one of those that'll lag behind you while you lead her if you're taking her anywhere she doesn't want to go. If she's interested in where you're going, she'll be jigging/trotting/staying right up next to you, but forget it if she doesn't like where you're going.
This has been frustrating to me for forever, since I got her, because who really wants to be practically dragging their horse behind them whenever the horse doesn't want to go?
She'd catch right up if I'd "tug-tug-tug" on her halter but then she'd start walking slower and lagging behind again.
I tried leading her with a dressage whip and doing that whole butt-tap "thing" when she'd lag behind but that just caused her to walk out to the side of me or charge ahead, then lag.
In any case, it was not getting solved and it's a pain to be always either holding your horse back or hauling her forward.
Somehow, one day I was trying to get her to walk more to the side of me (she likes to be really close next to me or right behind me when she's being led >.< ) and I ended up back by her neck/shoulder with her about 4 feet away from me, and she's walking like a dream. When she'd slow down, I'd pop her in the girth with the end of the lead rope and she'd start going an excellent speed again.
I still had full control (which she thought she'd play with by walking in a circle around in front of me to "turn" me towards home, hahahaha, however I caught her immediately and got her walk correctly) but we weren't playing tug-o-war anymore.
I'm not sure but it seems like making her "lead" to wherever she doesn't want to go is somehow making her think that wherever we're going is her idea and therefore not objectionable.
In the last few days, leading her down to the trails has been a dream. It used to be pretty annoying, trying to make sure she kept up and all, but now that she's keeping up, it's easy.
I don't let her do this going places she wants to go because she's already thrilled enough about them but for places she doesn't want to go, this seems to be encouraging her to be enthusiastic about where she's going all the time.
She even fell behind a little the other day, realized that she should be farther up (before I even corrected her) and trotted up to where I wanted her to be. Trotted! Towards work!
The world is ending!
Anyway, it's been really weird how fantastically it's worked. I never thought I could get Lacey to not be always walking behind me when she doesn't want to go (it's scary too because she has knocked me down, spooking at something, before).
