One of those little dogs that rich/stupid owners carry around. Their little paws rarely touch the ground, except to take a poop.
"Good grief, look at Paris Hilton's airdog. Little bitch looks like a rat... and the dog looks pretty stupid too!"

An airdog is a dog with long ears, usually a hound, that likes to look out the window while the car is going, making his ears spread out like wings.
Hey look! Sissy's doing the airdog again!
