"If you have a smaller pet, a dog or cat that can ride in the cabin with you, certainly that is better than riding cargo," said Dr. Brad Crauer, medical director at the Seattle Humane Society.
"If they're in cargo and you're checking them like baggage, you need to make sure that the space that they're traveling in, the carrier, is big enough for them to get up and walk around and turn around in. It can't be real small and tight. We want to make sure they're able to move around."
Give your pet a little food and some water before the flight -- but not too much -- since they can't go the bathroom.
As you plan your trip, talk to your vet. Your dog may need a health certificate. This is always required if the pooch is in cargo.
If your think you're furry friend will get really agitated by flying, you vet may be able to give you some anti-anxiety medicine, such as Valium.
