Taking a dog on a ferry is straightforward once you know which rules apply to your route. The same sailing can offer three different options — stay in the car, a kennel on deck, or a pet-friendly cabin — and the paperwork changes depending on whether you're crossing to France, Ireland or the Isle of Wight. Get those two things right and the rest is mostly about keeping your dog calm and comfortable.
Know your crossing type first
Not all ferries treat pets the same way, and the biggest factor is how long you're at sea.
On short crossings — Dover to Calais, for example, or Holyhead to Dublin — pets normally stay in your vehicle for the duration. There's no kennel to book and no cabin to upgrade to, but you usually can't sit with your dog either; you'll be asked to leave the vehicle deck before departure. That's fine for a short hop, but think carefully before doing it with a nervous dog on a longer sailing.
Longer routes to France, Spain, the Netherlands and Scandinavia tend to offer a choice: an on-board kennel, a pet-friendly cabin, or leaving the dog in the car. Kennel and cabin numbers are limited and are the first things to sell out in summer, so reserve them when you book the ticket rather than assuming you can add one later.
Domestic routes are different again. Crossings to the Isle of Wight, the Scottish islands and most UK coastal services sit outside the EU pet travel scheme, so there's usually no Animal Health Certificate to arrange. Each operator still has its own rules on leads, deck access and whether dogs are allowed in passenger areas, so check before you turn up at the port.
Assistance dogs are handled separately and are generally allowed in passenger areas and cabins. If you travel with one, tell the operator in advance so the right arrangements are made.
Kennels on board: basic but workable
Ship kennels are best thought of as a safe place to sleep, not a holiday. They're usually metal or plastic units, sometimes in a dedicated area with a small exercise space, sometimes tucked into a quieter corner of the vehicle deck.
What you'll typically find:
- Units sized from small for a terrier up to larger boxes for a labrador-type dog
- A bed or mat provided, though most owners bring their own
- Water bowls, sometimes fixed to the side of the unit
- Limited visiting — on some ships you can return to check on your dog during the sailing, on others you can't
- A marked walking or relief area, often on an open deck
Book the kennel when you book the ticket, and give the operator your dog's size and breed. Staff allocate units by size, and arriving with a much bigger dog than declared causes real problems. Ask whether you need to bring a padlock or whether one is supplied. Pack a familiar blanket, a water bowl, poo bags and a couple of old towels in case of accidents.
Pet-friendly cabins: the most comfortable option
A handful of operators offer cabins where dogs stay with you. They're the most relaxed way to cross and the first thing to sell out, particularly in school holidays.
The rules vary. In most cases your dog must stay in the cabin with you and can't be left alone while you eat or visit the shop, so plan meals around one person staying behind. Dogs normally travel on a lead in corridors and lifts, and many ships ask you to use a specific outside deck rather than general passenger areas.
Cabins are usually sold at a supplement and are often available only on certain ships within a fleet, so check the specific vessel rather than just the route. Bring your own bedding, a waterproof mat and something that smells of home. If you'll be making night-time toilet trips, ask for a cabin close to an exit.
Paperwork for UK and European crossings
For travel between Great Britain and the EU, your dog needs to meet the EU pet travel rules. In practice that means:
- A microchip, implanted before the rabies vaccination
- A rabies vaccination given at least 21 days before travel
- An Animal Health Certificate (AHC) issued by your vet shortly before departure — GB-issued pet passports are no longer accepted for EU entry
- A tapeworm treatment, given by a vet between 24 and 120 hours before arrival, for entry to Great Britain and for certain destinations including Ireland, Finland, Malta, Norway and Northern Ireland
An AHC covers a single trip but can be used for onward travel within the EU and for re-entry to Great Britain for a limited period, provided the rabies vaccination stays valid. An EU-issued pet passport remains valid for entering Great Britain.
Rules change, and they differ for the Channel Islands, the Isle of Man and Ireland. Check the current guidance on GOV.UK and confirm the requirements with your vet and your ferry operator before you book. If your dog is on medication or you're worried about the crossing, that's a conversation for your vet rather than a forum thread.
At the port and on board
Arrive with time to spare and walk your dog properly before boarding. Many ports have designated exercise areas, though they can be small; a decent lead walk just outside the terminal is often better. Feed a light meal a few hours before sailing rather than a full one on the ramp, and offer water regularly.
On board:
- Keep your dog on a lead at all times, and use a harness or slip lead in busy areas
- Check whether a muzzle is required — some operators ask for one in public spaces
- Take poo bags and something to clean up with; bins aren't always close by
- Avoid the busiest decks if your dog is spooked by engine noise or announcements
- Follow staff instructions about where your dog can go — deck access is a safety matter, not a preference
If you're travelling as a foot passenger, only some routes accept dogs and the rules are stricter. Expect to keep your dog in a carrier or to book a kennel, with limited or no access to lounges.
A short checklist before you book
- Confirm the pet policy for your exact route and vessel
- Reserve a kennel or pet cabin when you book your ticket, and state your dog's size accurately
- Check the paperwork for both legs of the trip and book the vet appointment early
- Ask about exercise areas at both ports
- Pack bedding, bowls, leads, poo bags, towels and any medication, plus a copy of your dog's records
Most crossings are far less stressful than owners expect. Sort the paperwork in advance, book the space your dog actually needs, and treat the sailing as a nap rather than an adventure. If your dog travels badly, speak
