The requirements for travelling with your pet will depend on where you're travelling to and from.
Usually, your pet will need to be microchipped, have a valid pet passport or health certificate, and be up to date with vaccinations.
When planning your trip, you should check the government websites for the country you're travelling to and from to make sure you have everything you need. You can also ask your vet for advice.
If you're travelling on a sailing where your pet is allowed outside of your vehicle, you'll need to bring a lead (or a carry case for smaller pets), and some ferry companies may require dogs to wear a muzzle.
