Final answer:
To in-check classified cargo, including animals, DOT forms about the animal's health, behavior, and training must be completed and submitted to the airline as required, which may vary from 48 hours prior to at the departure gate.
Step-by-step explanation:
When in-checking classified cargo, which may include transporting animals, the Department of Transportation (DOT) has developed specific forms that need to be completed. These forms are designed to attest to the animal's health, behavior, and training.
Airlines often have different requirements for when these forms must be submitted. Some may require these forms 48 hours before travel, while others may need them at the departure gate. For passengers with service animals, such as a Seeing Eye-certified dog or other officially trained service dogs, providing these necessary forms typically poses no problem as the certification process includes ensuring the health, behavior, and training criteria are met.
