No guess on the horse, too far away and it is often hard to tell by a pic anyway.
As for the fencing, they couldn't pay me enough to put that around where I have my horses. My Beau is right, that stuff with break with very little pressure and leaves horribly jagged edges that are sharp enough to cut you if you touch it. IMHO, it is more dangerous than barbed wire. I would feel more comfortable containing mine with razor wire.
I like the Centaur fencing. Centaur HTP: Horse Fence Systems
It is similar to what My Beau posted but I think it is slightly better quality.
