The Dumb Friends League Furry Scurry is an annual two-mile walk for animals that traditionally takes place at Denver’s Washington Park on the first Saturday in May. It is the Dumb Friends League’s largest annual fundraiser, with more than 12,000 people and 5,000 dogs joining us for the walk and raising funds for the homeless pets in our care. The Furry Scurry has become a tradition for many Denver-area residents.
