Sorry if I sound like an ignoramus, but I have very little experience with ulcers. When they are home my horses live out and have access to free choice hay, so they are pretty low risk. We recently went on an overnight trip with my horse where he was stalled for 3 days. I noticed he was eating about half as much hay as he normally would, and he seemed a bit overwhelmed at times by the activity in the barn. He started to get a little girthy, but I shrugged it off, thinking he was being a brat - he is very opinionated, and I was doing the girth up a little tighter than I would at home.
Now that we are home, he has been totally grumpy under saddle. When I ride him at the walk he is fine, but as soon as I ask for a trot he bucks. The first ride, he trotted a little then started bucking. Now as soon as I say his name to ask him to trot, he bucks. My first thought was saddle fit, and I have the fitter coming out to check, but as far as I can tell the saddle fit is good. He hasn’t palpated sore in his back, but he’s been going fairly normal on the lunge.
I am thinking about kissing spines, but I can’t understand why that would suddenly present itself as an issue after this trip.
I sent an email to my vet, but I thought I’d post here as well. What do we think? Saddle fit? Ulcers? Kissing spines? Something else I haven’t thought of?
