I have 3 dogs and don't want to clean 12 paws, especially since we go in and out all day long. When we go in the back yard, there is a 4 part system: some of the dirt on the path to the deck is covered with indoor/outdoor carpet, then they play on the deck for a few minutes, and then when they go in we go through the laundry room that has a flat ikea rug, and then through the kitchen that has vinyl, before we get to the hardwood/rugs. So that is 4 non dirt surfaces.Our summer has not been that warm, only a few very hot days. Personally, I don't mind it getting colder. But I do mind it getting wetter. More paw cleaning before we can go back inside again But hey, at least we get all those beautiful autumn trees, I love that!
