I was able to get in touch with my contact who does this quite regularly with her very expensive puppies she ships.
Advice given:
If you use an airline like AA they won't ship dogs with flat faces due to breathing issues.
She exclusively uses American A.
They won't ship if departing location, or stops or destination locations are <30 degrees.
If the pup is > 12 weeks old they will require a vet letter in rabies vaccination.
Dog should be microchipped.
You will need some various other forms from the vet as far as breed verification.
Crate should have a pad in it. Not just paper towels or newspaper.
Crate will need two bowls attached to front door. Need to supply some kibble for food.
Said all info can be found on AA cargo on website.
She ships to various law enforcement and military agencies all over and has never had a bad experience.
She says she won't use a ground shipper or transport because they put multiple dogs together and in her professional opinion they don't take care of the dogs well.
Vet will need to supply a health certificate. It will be good for 10 days.
Hope this helps you.
