Heartworm endemic levels refer to how common heartworm disease is in a specific area, often based on reported cases. Some regions have a higher risk year-round, while others may only see cases seasonally.
Some destinations reference heartworm testing or prevention in their pet import requirements. If heartworm applies to your trip, it will appear in the destination-specific requirements shown in the PadsPass app for supported destinations. Your veterinarian is the right person to advise on heartworm testing and prevention for your pet.
Before you travel, make sure your pet's profile is complete — microchip number, the date it was first scanned, and your pet's most recent rabies vaccination (the two most recent if possible). Always confirm current rules with your airline and the destination's official animal import authority.
