Dog Park at the Burbank Airport
If you have a dog and are traveling into Burbank Airport there is a pheasant "surprised" outside Gate 4, it is a Dog Park with Shower inside the terminal.
A growing number of US airports have installed airside pet relief areas, apparently following a DOT rule mandating that terminals serving more than 10,000 passengers per day need to have one.
