Traveling in an airport and on airplanes can be particularly challenging. Many dogs get anxious in large groups of people, or excited to play with potential new friends. Insure your sanity and your pup’s safety, airport pet carriers help keep them calm and by your side as you make your way to your plane.

Many airlines allow you to bring small dogs in the plane cabin with you, so long as you use an Airline-Approved Dog Carrier.

These hard-side or soft-side carriers must fit under the seat in front of you, and your dog stays tucked inside for the duration of the trip. Each airline has its own rules, so be sure to check with your airline for specifics. Larger dogs need to travel in the luggage compartment in a specially designed Airline-Approved Dog Carrier for big mutts.
