Dogs entering from rabies-free or low-risk countries are not required to show proof of rabies vaccination but must complete a CDC Dog Import Form. Dogs entering from high-risk countries for rabies must have proof of a valid rabies vaccination and may be subject to additional quarantine or certification requirements.

For dogs coming from screwworm-affected regions, a health certificate issued by an official veterinarian is required, confirming the dog was inspected and is free from screwworm or has been treated. For commercial or rescue dogs, specific import permits may be necessary. Use the APHIS VEHCS for assistance.

Dogs arriving from rabies-free or low-risk countries must have a microchip that can be detected with a universal scanner. Microchipping is recommended but not required for dogs from other regions.

Service dogs and other assistance pets must meet general health requirements and specific guidelines depending on the purpose of travel and destination. Contact CDC or APHIS for additional support if traveling with an assistance dog.

The Centers for Disease Control and Prevention (CDC) requires that all dogs appear healthy upon arrival in the United States. Dogs are subject to inspection at ports of entry and may be denied entry if they show evidence of illness, including zoonotic diseases. APHIS also has requirements for certain conditions like screwworm. Additional regulations apply to dogs used for commercial sale, adoption, or those arriving from countries with different risk levels for rabies. Dogs from dog rabies-free or low-risk countries must have a CDC Dog Import Form (https://www.cdc.gov/importation/dogs/rabies-free-low-risk-countries.html).
