The Centers for Disease Control (CDC) has extended existing air waybill waivers to May 1, 2025, pertaining to dogs entering and/or reentering the U.S. This extension only waives the CDC pre-arrival air waybill requirement. All other responsibilities outlined in the Aug. 1, 2024 final rule remain in effect, including: Ensuring dogs have proper documentation, making staff available in the arrival area until dogs are cleared and collected, and facilitating the prompt return of dogs denied entry within 72 hours. These regulations apply to all air carriers, charter operators, and private aircraft.
