TERMINAL 4: The "Bone Yard", located outside the baggage claim level on the west end, "Mutt Mitts" are provided for owners to clean up after their pets and water buckets are available for a drink. Two water faucets are located within a lighted area filled with gravel in the shape of a bone.
TERMINAL 3: Sky Harbor added another pet park called "Paw Pad" outside Terminal 3 near the base of the control tower.
TERMINAL 2: Just recently added "Pet Patch" just right outside Terminal 2.
These are some of the tips I saw online for traveling with animals.....
Do not tranquilize your pet, as the effects of tranquilizers on animals at higher altitudes can be unpredictable. (Phoenix is at 1,000 above sea level - so problem there)
The Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA) has set up rules and regulations for the transportation of live animals, and your pet is required to be at least eight weeks old and fully weaned before traveling by air.
Whenever possible, book a direct, nonstop flight and avoid holiday or weekend travel.
Try to plan schedules that minimize temperature extremes. The kennel that you use must be sturdy, properly ventilated, and large enough for your pet to freely be able to stand, turn around and lie down. ( LOL, well, if you are traveling to Phoenix then, to minimize temperature extremes you would only be able to travel here during ahhhhhh January and February)
Get your pet comfortable with the kennel prior to flying; this reduces stress on your pet. (I can't imagine ever traveling with Bandit - the dog from He**)
Give your pet food and water within four hours before your flight. You will have to sign a certification of the time when you last offered food and water to your pet.
Give yourself plenty of time for check-in so there is no rushing and everything is done properly (I swear - this is what it says - no rushing LOL)
