 And by the way, you're pretty much gambling with your pet's life no matter what kind of dog or cat you have if you ever decide to put your pet in the cargo hold of a plane. You can never predict the air quality and temperature in the cargo hold. Pets have froze to death, overheated to death in cargo holds. Pets have been lost. If you love your pet, never, never put him or her or any living being in the cargo hold of a plane.
