The most useful single reference seems to be the “Pets: Cats, Dogs and Ferrets” page of the German Missions in the United States, followed by the USDA’s page titled “Taking Your Pet to a Foreign Country“.
In summary:
Pet relocation .com has a nice page with the german import rules.
The USDA’s APHIS has a page titled “Taking Your Pet to a Foreign Country“. It states, in part:
International health certificates for the export of animals from the United States are completed by the APHIS accredited veterinarian who certifies animal health status, conducts tests, and records test results for the individual animals being exported. Completed and signed international health certificates for the export of animals from the United States must be endorsed by a Veterinary Services area office in order to be valid. To obtain the USDA endorsement of an international health certificate or any other documents relating to traveling with your pet, the documents must be completed by an APHIS Accredited Veterinarian.
The APHIS Area Office for your state can assist you with your questions relating to traveling with your pet, help you locate an Accredited Veterinarian, and inform you of the fee(s) for the USDA endorsement(s). You should check with your current Veterinarian to determine if he/she is an APHIS Accredited Veterinarian.
The airlines have their own rules and fees:
