Most airlines treat animals as an afterthought, which makes flying with pets a real hassle. Airports are required to have relief areas for service dogs, but the facilities provided usually require passengers and pups to leave the terminal and go back through security when they're finished.
Now pets going through San Diego International Airport have a new, and much more convenient, option for taking a pre-flight bathroom break. In April, an indoor pet relief area opened  next to the human bathrooms between Gates 46 and 47. The amenities include fake grass, a red fire hydrant, poop bags, and even sinks for the humans to wash their hands. Maintenance workers clean the canine restroom twice a day.
San Diego has four other doggie bathrooms, but like most other airports, they're located outside the terminals. Also, good news for pups not flying in and out of San Diego. The design firm that worked on the relief area is now offering the plans to other airport clients, so hopefully we'll see more of these in the future!
