My TWH, Major, is a jumpy kind of horse. He is getting better, but while tied up he gets really scared. Every noise he hears he jumps and pulls back hard on the lead rope. Anytime I have him tied I stay right next to him to make sure he doesnt break his halter or lead rope and go running off. It has gotten extremely tight though. When he does jump, I pet him on the head and talk softly to him and take his halter and get him to take a step forward. He will blow then settle down till he hears another noise. Is there any tips that will help him be more calm while tied or is it just one of those things he's going to have to have a lot of?
