So what kind of suggestions would you make for neighbor outdoor dogs that keep digging under the fence to my yard. My dogs are small and are indoor dogs and I don't want have them get killed if I let them out to go to the bathroom. They can get under the fence where the neighbor dogs dig much easier than the large neighbor dogs. We are half burying a sheet steel on a roll, as a temporary measure. We dug a trench on our side of the fence and rolled out the steel, sitting up vertically, and burying the bottom half. I know this stuff will eventually rust out, but I consider it to not be a permanent solution. This neighbor refuses to acknowledge that his dogs are even digging the holes, despite the dirt being on his side of the yard. Everything is not his fault and is automatically ours. What would you suggest?
