What happens when four dogs made famous by the Internet take a photo together? It goes viral, of course.

Four-legged stars Tuna, Dagger, Trotter and Biggie - each with its own devoted Instagram following - met up Saturday in San Francisco's Alamo Square Park for what has been deemed a "Dogameet."

Courtney Dasher, the owner of Tuna, a chiweenie known for his overbite, posted a photo of the fierce foursome together to Tuna's Instagram account. Days later, the photo already has more than 25,000 likes.

"We had an insta meet with some amazing folks from @instagram and some fellow furry instagrammers!" she wrote.
