We live in a high fenced yard in the suburbs with 2 alarm dogs (inside at night) yet close to open space. We havent seen raccoons or opossum in our yard since getting the dogs but they do frequent the neighbors pond and feast on her fish. Ive seen fox on our road at night and hawks in the day and a skunk visits at least weekly. Are we still at risk of diggers infiltrating so that we HAVE to make an apron and bury the hardware wire? Our dogs will not dig and the coop/run is just feet from our house.
