Yes I agree I would be insisting that I either choose which horse I ride (within reason obviously) or I'd take my business elsewhere.
Arab is spot on.
I really don't like riding instructors who pedal horses as "difficult" TBH. It gives the horse a negative label and a bias against the horse, the riders are either more nervous if the horse or they'll go the other way and get heavy handed from the get go.
and then everyone wonders why these horses behave the way they do and it's reinforced for them day in day out.
Riding school horses are rarely difficult horses and tbh I also think it's dangerous for instructors to try to push the "you'll get experience riding difficult horses" line.
My horses are lovely and they are really respectful. But if you handled them like a lot of so called difficult riding school ponies are handled they'd show you what a difficult horse is. I'd put money on it that you'd be severely injured.
You sound like the sensible sort but can you see how it encourages people who do have an interest in eventually working with horses to make them good horses to think they have experience with difficult horses nd a lot of the time they get out of the riding school and quickly find out how "difficult" 500kg of animal can get when you get it wrong lol.
She really doesn't need to be pushing it on you she just doesn't.
Argh this has irked me lol. I hope they sort it out!
