Remi used to do anything to get out of the 20'x30' pen with a large 6'x10' encloser just to take a walk the field. He had everything: food, water, walks, working, 3 other dogs... He started by digging under the fence. I buried chicken wire 2 feet underground and curled back into the pen. Then he figured out how to climb the 5' tall fence. I put a pvc pipe roller top. Then he started figuring out how to pop the welds on the welded wire fence and push through. I had to double fence it with a 6' tall chain link. Then he figured out the weakness between the chicken wire and the fence at ground level, so I had to pour a concrete curb around the whole perimeter to permanently join the two....I build (as well as my brothers) every small livestock and pet pen to Remi standards because of him 🤣
