Travelling abroad with a diabetic dog or cat from the UK

Quick answer

Whether your diabetic pet should travel is a question for your vet. If your vet is happy, the next job is the paperwork, and it needs weeks rather than days. From Great Britain, a dog or cat going to an EU country needs a microchip, a rabies vaccination and an animal health certificate from an official vet. Everything about insulin, meals and timing on the journey comes from your vet, not from this page.

This page covers the logistics only. For storing and carrying insulin, see storing and travelling with pet insulin.

Ask your vet before you book anything

Book a conversation with your vet before the tickets, the ferry or the hotel. Take the dates, the length of the journey and where you are going, and ask:

• Are you happy for my pet to make this trip?
• What do you want written down for the journey and for the stay?
• How much insulin and how many supplies should I take?
• What should I do if my pet seems unwell while we are away?

Write the answers on paper. Your vet may suggest a practice run or a check-up before you go. Mello is a tracking tool, so your vet is always the one to ask.

What does a dog or cat need to enter the EU from Great Britain?

These are the steps GOV.UK sets out for dogs and cats in general. They do not change because your pet has diabetes, but they do need to fit around your pet's routine.

1. Microchip. Your pet must be microchipped before, or at the same time as, the rabies vaccination, or they will need another vaccination.
2. Rabies vaccination. Your pet must be at least 12 weeks old. If a first vaccination is needed, you wait at least 21 full days afterwards before you can travel. A booster does not need that wait if your pet's cover was never interrupted.
3. Animal health certificate. Your vet must be an official vet to issue it. It is valid for 10 days for entry to the EU, counting the issue date as day 1. It is valid for 6 months for onward travel within the EU and for coming back to Great Britain. You need a new one for each trip.
4. A declaration. Your vet gives you a declaration to sign, confirming you will not sell or re-home your pet while abroad.
5. Tapeworm treatment, for dogs. Some countries require it, so check your destination.
6. Arrival. Enter through a travellers' point of entry and carry the certificate, which shows the microchip and rabies vaccination.

A pet passport issued in England, Scotland or Wales cannot be used to enter the EU.

Work backwards from your travel date

The 10-day window and the 21-day wait are the two dates that catch people out. A simple order:

• Ask your practice now whether they have an official vet. If not, ask them to help you find one.
• If a first rabies vaccination is needed, book it as soon as you know your dates.
• Book the certificate appointment so the issue date falls within the 10 days before you enter the EU.
• Ask the practice to fit appointments around your pet's usual meal and injection times.

What about Northern Ireland and countries outside the EU?

Northern Ireland has different rules, and a separate scheme for travel from Great Britain. Read the Department of Agriculture, Environment and Rural Affairs guidance rather than assuming the EU steps apply.

For a country outside the EU, GOV.UK says you need an export health certificate and, from England, Scotland or Wales, an export application form. You nominate an official vet, and you must check the destination's own rules for extra requirements. Each country and pet has its own instructions, so start with the country's page and give yourself longer.

Carrying insulin, syringes and supplies

Ask the airline, ferry or rail operator before you book, not at the check-in desk:

• Can I stay with my pet, and can I carry insulin and syringes with me?
• What paperwork do you want to see for medicines and needles?
• Is there anywhere to keep insulin cool on the journey?

Keep insulin and supplies with you, take more than you expect to need, and ask your vet for a letter that names the medicines you are carrying. The travel and sitter checklist has a packing list you can print.

Time zones and your pet's routine

If the trip crosses time zones, or the journey runs through a mealtime or injection time, do not work out the timing yourself. Ask your vet for a written plan that covers the journey and the stay. Mello records what was given and when, so you and anyone helping can see the plan being followed.

Find a vet at your destination before you go

Before you leave:

• Find a vet near where you are staying, and a 24-hour practice, and save both numbers in your phone and on paper.
• Ask your own practice for a written summary of your pet's care to show an unfamiliar vet.
• Ask your insurer, in writing, whether treatment abroad is covered, in which countries, and what you must do before you leave and when you claim. The pet insurance questions page lists what to ask.

If anyone else will be looking after your pet while you are away, see leaving a diabetic pet with a sitter or boarding a diabetic pet.

Coming home

GOV.UK says the rules for returning depend on the country you are coming from. For an EU trip, the certificate stays valid for re-entry to Great Britain for 6 months, but check the GOV.UK guidance for your route before you travel, because requirements for returning can differ by country.

How Mello helps

Mello is free to use, with an Emergency Card and unlimited logging, so there is one place for the routine and your vet's details wherever you are. If a family member or a carer will help, Shared Care lets them record what they gave and when. Shared Care is part of Premium (GBP 7.99 a month or GBP 59.99 a year). You can join the early-access list to hear when it is ready for you.
