You should ask a pet shipping company to help you if you plan to send the dog to your friend without your accompany. The company can help you get everything ready. It costs extra money if you ask them to handle everything. The procedure isn't complicated. If you plan to prepare the required documents, you should follow the following procedure.

1. acquire the quarantine certificate. You should have it from the quarantine bureau. Actually, some pet hospitals can help you get it. You just need to pay them money.
2. a shipping box. It can be acquired at the pet hospital or from the airport.
3. an automatic waterer for your dog. Make sure that your dog know how to drink water from it.
4. an identity card for the dog. It should include the dog's name and its owner's contact info.

When you prepare all the required documents, you can send your dog to the shipping company. Some shipping companies come to your home and pick up your pet. They might charge for this service.

PS: if your dog has air-sickness, you should feed it with some medicine.
