I talked to a horse friend today. We were looking at my barns and he told me about a barn his friend built. I believe his friend's whole barn was built this way but I think it would be great for dividers......
He said the corners were built out of steel. Not sure if it was "c" purlin or some kind of angle iron. The corners formed a slot. They then slid 2 x 4's into the steel corners to make the walls. Each board stacked on the previous board. No need for screws or nails. If a board got broken, the ones above it were pulled back out and the broken one replaced.
Sounds like they could be made as tall as you want them to be (or as short). They can't chew on the wood as easily because the ends aren't exposed at all and the edges are too close together to get a bite.
