The absolutely incredible image of a dog bathroom sporting a fire hydrant, above, was taken at the San Diego International Airport.
As of 2009, the Department of Transportation has apparently required all airports to make sure that there are pet relief areas available for any passengers traveling with service animals. The website Petfriendlytravel provides a handy guide to pet bathrooms across the US, and confirms that there is indeed a fire hydrant in the San Diego location:
San Diego International has three pet and service animal relief areas. One is located outside between Terminal 1 and Terminal 2. At the Commuter Terminal, go to the west end; the area is located outside the terminal entrance. There is also a post-security animal relief area in Terminal 2 West, complete with fake grass, hand-washing station and a fire hydrant.
