Nooooo! I see Mel using the grenade launcher at goat noises neighbor...... say baaaa! now, ya jerk.....
I'm with Bay. Sister had buried invisible fence and a German Shepherd that loved to chase squirrels. You have no idea how often they came home with him waiting to get back on the property. Besides that you need to worry about the batteries in the collar (do they make them in Mel's size?). A single strand of hot wire inside the fence should work, he can climb but I don't think he could clear a 4' fence without touching it. And you don't live on a road with a lot of walkers, get some of the electric fence signs like Bay suggested.New fence will be no climb, may get hot wired, or invisable fence a foot inside of outter fence.....
