Puppies and kittens traveling within the U.S. and Puerto Rico need to be at least 8 weeks old to travel with United. If you’re planning to transport puppies and kittens that weigh less than 2 pounds, they must be at least 10 weeks old.
The minimum age for international travel varies depending on where your pet is traveling to and from. For travel into the U.S., the rabies risk designation of the origin country determines the requirements. Puppies being imported into the U.S. from high-risk locations need to be at least 16 weeks old and fully immunized against rabies before being brought into the U.S. The rabies vaccination must be given when puppies are at least 12 weeks old and at least 30 days before they arrive at a U.S. port of entry. Puppies being imported into the U.S. from a country with no- to low-risk of rabies can travel under the same policy as pets traveling within the U.S. or Puerto Rico. Puppies entering the U.S. as commercial shipments for the purposes of resale or adoption must be at least six months old, vaccinated for rabies and require a USDA permit-regardless of the country of origin.
International requirements can be complicated, so please contact an International Pet and Animal Transport Association (IPATA) shipper for help planning your pet’s trip.
Pets can sometimes have reactions to vaccines, so we recommend that they don’t travel for at least 24 hours after they’re vaccinated. It’s important to note that puppies younger than 16 weeks who haven’t received a complete series of vaccines might be more likely to get sick while traveling. We suggest asking your veterinarian to give your pet a more comprehensive exam, including testing for intestinal parasites, so they have a healthy travel experience.
