That's great info, thanks!
My house is three or four hundred feet from the road, I would say. And the places in the fence where the dog can slip under are toward the back. There's one spot that would let them out at the edge of some woods and another that would let them out into a neighbor's empty field. To get to anyone's house, they would have to go at least a half mile, I think, from any of the weak spots in the fence.
Do you keep yours in the garden? We're considering getting some to eat our squash bugs!
