The Purina Pet Parade, the world’s largest costumed pet parade, blends the festive spirit of Mardi Gras with the charm of adorable, dressed-up animals. Free for spectators, the event offers endless “AWWW” moments and easy access to the Taste of Soulard or Wiener Dog Derby afterward. Pet owners can register their furry friends online or in person at 12th and Allen to join the fun and showcase their style. Proceeds from the event support Open Door Animal Sanctuary, making it a celebration for a great cause.
