I know we have some neighborhood dogs and a few fox and I'm sure there are other random creatures roaming in the night. I don't want them eating my girls! I know that it's been said that you should bury the fencing about 12" down underground to discourage digging under the fence by predators. Have you done that? My husband feels it a little unnecessary and I know it's not terribly easy to do but is there anything that is as effective or moreso?
