First, go to your vet because you need the certificate from them that says that your dog is vaccinated and completley healthy for flying. Then you need to arrange it with the air plane companies and pay them the pet flying fee, and i think they are right, it varies on which air company your going to fly on, but most air plane companies wont take dogs/pets if the weather is really hot because that means they will have a higher chance of dying since pets are stored in the luggage compartment on the bottom of the air plane. United Airlines i think takes pets even if its like 95 degrees but its up to you!
