Show Steer quit leading

    Hey guys I'm new hear and I'm having some issues with my steer. So my she was walking really good. I could walk him pretty much anywhere except for a few instances, but recently i had a really busy week an didn't have a  chance to walk him. Forward a week to a couple days ago and I was really struggling just to get the halter and when I did he wouldn't budge at all. I've tried for the past 4 days to get him to walk again, but i have not made any progress. It's really disheartening because he was finally leading really good and now its all gone. Do I just need to start over again or is there something else since he was just walking fine a week ago? Could something be wrong with him? Thanks guys! 

Tie him up for an hour a day then lead him, when I say up I mean make his nose even with his ears where his head is flat across the top. For an hour and if he doesn't want to lead let him stand there... We generally always tie them before we lead if it's possible and it seems to help

Halter him and tie him in the morning. No feed or water until he leads.
