I would not let the distance interfere if I felt the pup and breeder were the ONES for me. Do you have a family member that would act as a courier for you? I would much rather send someone I know to pick up the pup than trust a stranger. Southwest Airlines has reasonable rates and they let the animal fly with you in the cabin for a $75 fee.
I bet you might even find a YT member that would act as a courier for you.
I would NEVER ship any animal in cargo. Many, many die in transit. There is a website that carries this info. Shocking! Just too many factors that could negatively impact the emotinal/physical well being of any animal, especially a puppy.
Another $500 to insure the right puppy travels to my home would be well worth it, if I could afford it.
Good luck in your decision.
