Please don't do it! For the sake of your puppy's physical, mental and emotional health! Especially on smaller domestic flights where the cargo holds are neither pressurised or climate controlled. In fact we submit that any breeder that recommends this practice is putting cost reductions ahead of the safety and well-being of the puppies they sell. Airfreighting puppies to customers is even more unethical than keeping "breeding stock" locked up in small cages/kennels for extended periods of time!
Don't take our word for it. Read these articles to see if saving a few thousand Baht justifies subjecting your young puppy to this traumatic experience.
We have several professional drivers that specialize in pet delivery. Your puppy will ride in air-conditioned comfort with the driver; that will let it out to use the toilet when he makes rest stops. He will feed and water the puppy at regular intervals, and give it a chance to stretch its legs, just as you would, if you were driving with him/her yourself.
If you prefer to pick your puppy up yourself, that is something you are welcome to do.. Although driving to pick the puppy up yourself often costs the same or more than having a pet taxi deliver it, Some people just fancy a road trip to pick up their new fur-baby. If that's what you want to do, we can certainly help coordinate the pick-up.
