My boyfriend has a stb gelding who has started misbehaving under saddle. I recently sold my mare who was his paddock mate we also bought them together he has only started acting up since she left. I now have a new pony who is unbroken so i cant ride with him. The stb does mini rears and mini bucks wont go forward nicely when he is ridden out alone. It is annoying/upsetting my boyfriend as he is only a beginner (the horse was sold to us as a beginners horse). Any ideas how to fix this problem or what the main cause could be? Seperation anxiety soreness etc? It has only started since my previous mare was sold. Thanks :confused: ';'
