We have 2 labs who love to run up and down our backyard fence line, so of course they've run a path into the grass to where there isn't any grass there. The neighbors who share the fence have a sprinkler system which mists enough water onto this "dog path" to make an awful muddy mess. I have thought of planting trees/shrubs along this fence to keep the muddy mess under control, but not sure if it will really keep the dogs from running up and down the fence. Any ideas??
