I would suggest using the metal over the board edges. I have successfully use 'dry wall corner bead', which is the right angle galvanized metal, complete w/ nailing holes in it, that builders use over corners of dry wall, for many years. Yes, it will eventually rust out, esp. if used outdoors, but it is easy to replace and not terribly expensive. That said...for wider lumber-like full dimension, or where thick plywood is nailed onto 2-by stuff, I used a plain galv. right angle metal flashing...comes in several widths, I *think*, including 2"x 2", or maybe 1.5" x 1.5", which is just right for such lumber. Works really well!
In these times, when most horses are raised in pens and often spend lots of hours confined, LOTS of horses will chew wood. I try to NEVER have any exposed wood within their reach.
