I created this potty area in the side yard for the dogs so I don’t have to go through the mud to pick up their mess. It went down pretty easily and lays nicely. I used a box cutter to trim it and got 6-inch stakes from an online retailer. I laid it over fine gravel (not quite sand, not quite PRA gravel) without a liner and added a pet-safe infill. I plan to use an eco spray every couple of days to eliminate urine smell. This way, the kids can play on the real grass with no more dead spots. Just have to train the dogs to use this area. My 9-year-old dog got it down in 2 days, but my 2-year-old is still a bit confused.
