NEW YORK, Aug. 28, 2026 /PRNewswire/ -- Somewhere in America right now, a dog is mid-adventure and it likely involves a whole lot of mud. Dogs weren't exactly built to stay clean. They are meant to chase, dig, splash, roll, run and, inevitably, come home covered in whatever they found along the way. This summer, Wondercide, the plant-powered pest protection brand that empowers people and pets to explore and play outside fearlessly, is celebrating that spirit with the search for America's Dirtiest Dog - a nationwide contest for the dogs who are living their absolute best lives, one muddy adventure at a time.
