Dog Urine Art (DUA) is best observed on the sidewalks of a big city, where the random patterns of wet dog urine assume abstract shapes as they dry on the pavement. If you live where your dog relieves himself/herself on grass, you are out of luck. Another reason that the city is good for DUA is that there are many dogs being walked in some of the neighborhoods, especially  mornings before work and at the end of the day, providing plentiful material. Don’t get too close and don’t overthink it. Just observe with the eyes and imagination!
