I have a 14 year old, 16hh Chestnut Thoroughbred mare (just so you can get a picture in your mind) who is extremely herd bound.
Currently she is pastured with a 9 year old mare and that mares 5 month old filly. Sassy, the TB is top horse in any pasture. We cannot separate her from the others.
Last weekend my mom asked if I wanted to go for a ride/walk. She wanted to walk as she doesn't ride horse, and I rode. The first about 1/4 of a mile she walked fine. She suddenly stopped, so I gave a firm nudge forward, she just stood there. So I gave her another and she started backing up. My mom had a lead with so I asked her to lead her, she walked fine again and my mom eventually took the lead off so I reasurred Sassy she was fine and petted her, worked for a while. Then she stopped again, and did the backing up. On our way home she crow hopped the entire time because I wouldn't let her even trot.
The reason I need to ride down this road is about 1.5 miles away from my house there is a stable and I'm going to be taking lessons there. There is no point in trailering a horse 1.5 miles, it would be a nice walk warm-up even though I do live in Minnesota. She had trailer issues when we got her, I fixed them and she loaded fine but we hadn't trailered her in over a year so she kind of forgot. The last time we loaded her it took about 15 mins (not force), but it took 5 of us at the vets to get her in. I'm going to be working on trailering next week. So I kind of want to leave the trailer option out of the idea.
She has a lot of groundwork on her. Our best riding horse except for this issue. She moves mostly off leg. We believe she was in race horse training but she never raced. She just had her teeth done, chiropractic work, vet exam, saddle fitting, hooves trimmed, etc... done a few weeks ago.
She also always wants to ride in the field, why I have no clue. I ride her on the shoulder/frozen grass part. She would be over belly deep getting into the field and the grounding is horrible in the ditch to get to the field. She isn't ouchy on the road, she just doesn't want to leave her buddies. She has always been like this except when we have had her pastured alone, but at the moment we can't do that.
Any ideas would be greatly appreciated.
