After getting over our trailering issues (yay!), my mare and I were able to haul out for a trail ride yesterday. We went with my sister and her QH, and the lady who took us rode her 4 yo endurance prospect.
My usually-perfect trail horse was TERRIBLE. The first mile or so was fine, fast walking on a loose rein, but eventually she started jigging and I just couldn't stop her. I tried collecting, one rein stops, all positions in the group, stopping, walking super slow, sitting deep in the saddle, backing along the trail, attempting walk/trot transitions...I could not get her to stop jigging, to the point where I nearly forgot what walking felt like. :P I got off and walked her for a few minutes and she was crowding into me the whole time. On the ride back to the trailer, we were back to fast walking on a loose rein which was great, but she jigged a few times.
I noticed that she tended to be better when she led the group. She led the first bit out and half of the way back. We were in our usual tack, fleece-covered s-hack over rope halter. I took off the fleece eventually, thinking it was too much padding, but that didn't make a difference. Most of the trail was single-track with ditches, rocks, and slight inclines.
Lia is usually the picture of perfection on trails, so I was very frustrated and disappointed with our ride. I don't understand why she was so jiggy this ride. She was perfect when we hauled out last week for a trail ride. At home, she walks out and back calmly, trots, runs hills, ditches/gets ditched by her trail buddy, and NEVER gets jiggy.
I'm sure I was not handling the problem correctly. I was probably putting the wrong pressure on her... If anyone has advice on how to deal with this, I'd love some help! I just don't know what to do since I've never had this problem with my horse. Thanks!
