Whether this is healthy for your pet and allows for adequate drainage, you might create a dog run on existing groundcover. Some of the best ground covers for a dog run are natural grass, rubber padding, and wood chips. Natural grass provides a comfortable ground cover enjoyed by most breeds. Although this is a common alternative used by many homeowners, before putting your run over traditional turf, there are a few considerations to take into account. Some dog owners prefer the look of wood chips spread over the fabric of landscaping, another common choice. This ground cover will undoubtedly make your dog run more visually appealing. However, wood chips provide an excellent breeding ground for bacteria – mainly as you can't merely rinse urine out of the run. You'll need to add more wood chips periodically to replace those lost while collecting solid waste and keeping this choice looking fresh. Finally, to make some of these dogs run groundcover choices even more comfortable to clean, you may want to consider adding a pheromone-treated urine handle, which will allow your pets to use only that area to relieve themselves.
