Pets (small dog, cat or ferret) are permitted to travel with foot passengers, but they must be transported to and from the ferry in a secure, rigid and appropriate pet cage or box (please bring your own). The pet must be able to stand or lie down in the cage or box in comfort and the owner of the pet must be able to carry the cage or box from the terminal to the ship. All pets must travel on the car deck in their cages or boxes. Please note that if you turn up at the port without an appropriate pet cage or box you will not be allowed to bring your pet on board. There are no exceptions to this rule.
Brexit: After 31st October 2019, you will still be able to travel with your pet (dog, cat or ferret) to and from the UK whether a deal is reached or not.
However, in a no-deal scenario, you may need to take some additional steps depending on how the UK is categorised from 31st October 2019.
Importantly, you may need to visit a veterinary practitioner some months in advance of travel, for certification and relevant vaccines.
More information can be found on the Governments’ pages about Pet travel to/from Britain after Brexit.
