Taking Dogs on UK Ferries: 2026 Operator Guide

Every major UK ferry operator now accepts dogs — but where the dog actually spends the crossing varies enormously by route. Short Dover hops keep most dogs in the car. Overnight sailings to Spain put them in dedicated pet cabins. Scottish island routes treat them as walk-on guests with their own deck. This guide breaks down every UK ferry operator's pet policy for 2026: who carries dogs, how, and what it costs.

Before the route-by-route breakdown, it helps to understand the four models UK ferry operators use to carry dogs. Which model applies depends on the crossing length and the operator's vessel design — not on the dog.

DFDS runs the busiest cross-Channel routes alongside P&O. On Dover-Calais (90 minutes) and Dover-Dunkirk (2 hours), pets travel exclusively as part of a vehicle booking — DFDS does not accept foot-passenger dogs on French routes, so a walk-on crossing is not an option. The pet fee is £15 per pet, per way, added to the vehicle price.

Dogs remain in the parked car throughout the crossing. DFDS allows owners to visit mid-crossing by asking at Guest Services on board, but pets cannot be brought into passenger lounges. The vehicle deck is well-ventilated rather than climate-controlled, so high-summer crossings carry the usual heat-management considerations — park out of direct sun where possible, leave a window cracked, and place water bowls in a non-spill carrier.

A significant policy change took effect in March 2025: DFDS now allows dogs to travel in cars on UK-bound legs as well as outbound, ending the long-standing freight-only restriction on the return leg. Practically, that means a one-way booking from Calais or Dunkirk back to Dover can carry a returning dog in the family car — useful if you're moving home from Europe or doing a one-way pet relocation.

P&O carries up to five dogs per booking on Dover-Calais, with two options for where the dog spends the crossing. The default is the same as DFDS: dogs stay in the vehicle on the car deck.

The differentiator is P&O's Pet Lounge, available from £12 each way per dog. It's a dedicated shared lounge — the owner and dog stay together throughout the 90-minute sailing — with seating, complimentary refreshments and an outside-deck exercise area. Capacity is limited and the lounge often sells out for school-holiday peaks; check-in is 90 minutes before departure rather than the standard 60, which catches out drivers expecting a normal turnaround.

Pets (other than assistance dogs) are not permitted in P&O's main passenger lounges or restaurants. P&O also will not transport UK banned breeds — namely Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro and XL Bully — and asks owners with crossbreeds that resemble these types to contact customer service before booking.

Brittany Ferries operates from Portsmouth, Poole and Plymouth to ports across northern France (Caen, Cherbourg, Roscoff, St Malo) and to two Spanish ports (Bilbao and Santander). The crossing length pushes pet accommodation from "stay in the car" territory into kennel-or-cabin territory.

Three options are available depending on the ship and route:

For the long Spain crossings (Portsmouth-Bilbao or Portsmouth-Santander run roughly 24-32 hours), pet-friendly cabins or kennels are the realistic options — the vehicle deck is closed-access on overnight sailings. Brittany Ferries also requires dogs to be on a non-extending lead and muzzled whenever they are in transit through the ship (cabin or kennel to exercise area, exercise area back to cabin) and pets are not allowed in bars, restaurants or other passenger areas at any time.

The Irish Sea has the most dog-friendly options of any UK ferry market, with both major operators (Stena Line and Irish Ferries) running dedicated pet facilities. Crucially, dogs travel free on most Irish Sea routes — fees apply only to optional upgrades like pet-friendly cabins.

Stena Line operates pet-friendly cabins on its Liverpool, Holyhead and Fishguard routes — the cabins are the most commonly booked dog option on overnight Liverpool-Belfast (8 hours) crossings. Stena added 70 new pet-friendly cabins across the Irish Sea fleet during 2023, easing summer-peak booking pressure, although busy weekends still sell out weeks ahead.

The booking cap is two pets per booking. Free onboard kennels are available on Holyhead-Dublin and several other Irish Sea routes for owners who prefer a lower-cost option, and the Stena Estrid on Holyhead-Dublin has a dedicated outside-deck exercise area for pets travelling in kennels.

Outside the pet-friendly cabin, dogs must be on a non-retractable lead and muzzled in any public area of the ship — including the outside exercise area, lifts and corridors. The muzzle requirement catches owners out who only carry a soft fabric muzzle for the vet; a basket-style muzzle is the safer choice for a 3-hour crossing.

Irish Ferries' standout feature is its Pet Den: an inside lounge with seating for owners, hooks for leads, snack and drink service, and direct access to an outdoor deck. The Pet Den runs on the James Joyce and Ulysses (Dublin-Holyhead) and on the Isle of Innisfree (Rosslare-Pembroke). Functionally it's the closest cross-Irish-Sea equivalent of P&O's Pet Lounge.

Six pet-friendly cabins are available on the James Joyce specifically — that vessel is the only one in the Irish Ferries fleet with cabin-grade pet accommodation. The Rosslare-Pembroke crossing has no pet-friendly cabins, so the Pet Den, kennels, or staying in the vehicle are the three options on that route.

Pets travel free of charge on all Irish Ferries UK-Ireland routes. The Pet Den itself is included in the standard booking — owners do not pay extra for the lounge access — but capacity is limited and reserving a Pet Den spot at booking is essential, particularly on summer weekend crossings.

Caledonian MacBrayne (CalMac) is the principal operator for the Hebrides, Clyde and Northern Isles connections — 28 ports serving 50+ routes from short Skye crossings (Mallaig-Armadale, 30 minutes) to overnight Outer Hebrides sailings (Oban-Castlebay, 5 hours).

The CalMac pet policy is the simplest in the UK ferry market. Pets travel free of charge. Every pet still needs a ticket on the booking, regardless of whether they're staying in the vehicle, walking on with a foot-passenger booking, or sitting in one of the dedicated indoor pet areas on the larger vessels.

On most CalMac ships, dogs are permitted in all outside passenger areas and many of the larger vessels (those on Hebridean routes typically) have internal pet zones with owner seating. Pets are not permitted in any food, beverage or carpeted areas for hygiene reasons; assistance dogs are exempted and may go anywhere passengers can.

Two CalMac-specific details worth noting before travelling to the Scottish islands:

Crossings between Great Britain and the EU (Channel routes, Spain routes) require full pet-travel documentation since Brexit. Crossings between Great Britain and Northern Ireland or the Republic of Ireland are within the Common Travel Area and have lighter requirements — but Irish Ferries and Stena Line still recommend the same paperwork baseline.
