Ensure your pet stays healthy on holiday
Travel to warmer climates could expose your pet to serious or even fatal diseases not present in the UK, for example, Heartworm, Leishmaniasis, Ehrlichiosis and Babesiosis. Protection against these is not a requirement of PETS but we advise you to take precautions to safeguard the health of your pet abroad.
Please ask advice from one of our veterinary surgeons and for a copy of our leaflet ‘Travelling Abroad With Your Dog’.
