Fetchdog: Tips for Travel with Fido, From an Airline Industry Insider, by Susan Kerwin-Hagen: I keep a backpack that is designated for my dogs, which always includes: Paper towels for clean up; a spare kennel blanket or an old T-shirt with my scent; shredded newspaper if I’m traveling with a young dog and/or anticipate a long flight (accidents happen, and the newspaper will absorb them and help keep your pet cleaner); a travel bowl for food and water; a small bottle of antibacterial cleaner; dog biscuits; a large bottle of water not from the tap (pets become dehydrated during flights just as you and I do); dog food; my dogs’ health certificates; a collar, leash, and travel dog tag (put the word "Reward" with your phone number on the dog tag instead of his name); and first-aid items like an antiseptic stick, first-aid tape, benadryl, and vitamins.
