It might just be too tall for him to step over. If it's at or near his hock, he can't lift any higher.
I'd be worried about that t-post too. Anything you can do to protect him from it? A piece of PVC pipe over it maybe?
You could take it at the trot, let him jump it :~D
I don't think so:), There is only a very narrow space to cross it, the high gate on one side and thick brush on the other. It's a tight squeeze.
I never thought about putting some PVC pipe over it, Might help. It's an awkward crossing, but he went so easy for a while, he took me by surprise the first time he started to refuse.
