Hey, the horse I ride for dressage ( a 20year old riding school horse) is extremely lazy and stubborn and becomes quite dead to my leg, when I have my privates on him he is perfect but when in the warm up ring and show ring he is awful I spend my warm battling with him and when I finally get him forwards he will have a fit but on a good day he is amazing in the warm up ring just gets distracted by the door being open. As soon as I go into the show ring he losses all the energy I have built up and we end up with bad marks as he wasn't forwards enough, also I'm having difficulty getting him in the bit like he won't go on at all. Any help and advice for this would be amazing
