Travel in Countries other than the United States and Canada There is six months' quarantine for all dogs entering the United Kingdom. Quarantine regulations seem to apply to insular countries and have been made to prevent the introduction of contagious diseases such as rabies. In planning a trip to a foreign country, contact the consular service or embassy of the country to be visited to determine the status of quarantine and other regulations. We would further suggest that you carry with you during foreign travel a recent rabies inoculation certificate, along with an up-to-date health certificate from your veterinarian.
