i did something this past fall when i was breaking a calf, we had just gotten, halter never been on before, i didnt tie her up the first time, i simply grabbed the rope and let her run around me, me pivoting along with her, keeping tension of course,she would get tired and quit for a minute, and i pulled up on the rope close to her and scratched her. She didnt like that and we went at it agian for about 10 more minutes. Doing the same thing, just circles and pet, then i rubbed some sweet feed all over the halter and my hand, did the same thing. She stopped going in circles and was gentle as dog, i could lead (not drag) this calf that had been haltered for 3 days out side ethe barn, like that easy.
just what i do, being a year old and bigger is gonna be a little tougher
