5. Consider wheels
If you are traveling far enough that you have a layover, you’ll want to make it a long one, so that you and your dog have the chance to exit the airport, find the pet relief area, and return through security. Some pet relief areas are conveniently located and easy to find, but many are not — and sometimes the gate you arrive at is a remote one. You’ll need to hurry to achieve your goals, and wheels help. Chloe’s a small dog, but by the time I get to the pet relief area in Denver she effectively weighs about 57 lbs.
Only one of my favorite carriers (the Pet Pilot XL) has wheels, and it’s really too small for Chloe. Wheeled carriers that comfortably fit a dog Chloe’s size are typically too big to work as in-cabin carriers, unfortunately, but owners of dogs under 10 lbs. should give wheels serious consideration.
