Getting him to move his feet.
Thunder does great in the isle and in the arena with walk and whoa, but when we get into a new environment, or an area he doesn't go all the time, he plants his feet, raises his head and starts backing up. As soon as I get back to his side and give him a tug and say walk and start moving forward, he starts backing up then plants his feet. After a lot of struggle with this, usually he just gets too tired and gives up or I almost everytime have to have someone get behind him and urges him forward. I try to keep myself facing forward and looking straight ahead, but for some reason it doesn't help. It sounds to me like a small trust issue, but also stubborness. He was doing it for a while when I'd put him back outside after a workout, but we fixed it but reacting before he did. I tried that in the situation mentioned above, but it doesn't work. Any suggestions? We always seem to just keep getting further back lol.
Oh and I just wanted to add that it's not usually fear, I know the difference when He reacts to being scared, or if he's just testing me.
