Some sections are all barbed wire,
Some have two rows of barbed wire with a wire net underneath it.
The good thing is that the posts of the fence are all really sturdy, so if I need to put in another kind of fencing I could use the posts from the old fence.
I was thinking about just putting up some hot wire around the inside of the fence to keep him off the fence line, using the yellow things pictured below. But I am not sure.
I have never built a horse fence before. What would you guys do in this situation?
