Be prepared to pay extra fees.
Bringing your best furrrend on your trip is definitely not cheap. Depending on the airline, flying just one way with your dog can cost over $100. Budget your trip and see if there is room to bring your pup on board with you, or if he should stay back for a special week with Grandma and Grandpa.
Make sure that you have a health certificate for your dog from the vet.
Even if your airline doesn’t specifically call for one, go ahead and get a health certificate from your vet just in case. It doesn’t cost too much, and it’s always better to be safe then sorry. This certificate will show that your pup has had all his shots and vaccinations, and is perfectly A-OK to travel in-cabin with you and the rest of the passengers.
Line your pup’s carrier with DryFur pad.
No matter how potty-trained your pup is, accidents happen, especially in high-stress environments. Line your dog’s carrier with DryFur which wicks away moisture to keep your pup comfortable. If you think he needs to pee, carry him into the restroom with you with a wee wee pad and see if he can go there.
