This is not permanent for the horse. She will only be there in the summer. This is for my grandmother and she wants goats and cows. The amount of fence for the goats is not an issue, its the cows. The property is NOT fenced, it only share a fence with the national forest hence the barbed wire. Im not worried about my mare messing with the fence, its the bulls and cows. They are all black Angus and large, we don't need one walking through the fence, setting her cows, and possibly my horse loose. Could we use wire (not barbed) to fence off the parameter then extend the electric where we want the animals so no other cows/bulls tare it apart?
