I have an older mare that I bought as broke. All lies haha. I have been using your tips and videos to great success so far with her leading and standing still under saddle and still for farrier. I have hit a lull with her under saddle. She is still when I mount but as soon as I apply pressure to move forward she stiffens her legs and turns to try and bite. She does the same if trying to turn her with the reins. Please help lol
