I know how much it stinks (literally) to carry around a smelly turd on a hot day. Since my neighborhood is great for walking, I have a lot of friends who pass by with their humans in tow.
I decided to add a doggie amenity station to the corner of my fence: water, trash, poop bags. I had a small seasonal faucet installed in this corner when I had the irrigation installed... partly so i can easily water in my new plantings on this side of the yard... but really... let's be honest... partly for the dogs.
