Arch Bark

Arch Bark is one of the many pet-friendly events hosted by Gateway Arch Park Foundation.

Arch Bark is back on Saturday, April 18, 2026, and it’s the most tail-wagging day of the year. From 10 a.m. to 2 p.m., Gateway Arch National Park transforms into St. Louis’s ultimate dog-friendly celebration, free for every pup and their person.

Kick off the morning with our community dog walk through one of the country’s most iconic national parks, then stick around for Purina Incredible Dog Team performances, a Dog Fashion Show + Best Trick Contest, a tennis ball pit, free caricature drawings, local vendors, food trucks, lawn games, and more.
