Hi! I know nothing about neuro, but my mare had ulcers we started treating and there was no change in her lack of appetite over a few days, vet mentioned lets treat for HIND GUT ULCERS with Misiprostol (sp?) And she started eating again within 1.5 days. So a round of that may help? You can get it at cvs n sign up for the gold rx program itll save you almost 100 on the prescription
The other question I had was why did she have to stay in due to weather please? At her age and tempermant even being turned out during the day in crappy weather with a sheet and good amounts of hay would be better than in a stall don’t you think? Just my two cents. Until my mare hit about 20 or 21, she was on outdoor her whole life and she was a firecracker when i bought her, she was 7 then. I think being out all the time just helps them so much vs stalling, or at least getting daily turnout with a sheet or medium turnout on if its cold n rainy. Maybe try setring her turnout no matter what and see if that helps at all?
I agree with everyone who has said it but to say it again, please wear a helmet around this horse, period, and if your daughter has to ride her, maybe a lunge session with her trainer first just in case she has a wild hair in her to get out would be a good precautionary idea?
Best of luck and huge jingles to you all!!!
