I'm sorry I shouldn't laugh, but that last part was hilarious!!LOL We've never had a problem with ours going over fences, but we did have a problem once while visiting my parents when they went UNDER the fence. However, we haven't had any troubles since we put a single wire electric fence around the bottom of our privacy fence. They don't even get CLOSE to going under anymore and they wouldn't get close enough to go over either even if they wanted too. LOL At first I was a little against the electric fence, but I feel much better knowing they won't attempt to dig under and get out onto the busy road near our neighborhood.
