There are many smaller ferries that are pet friendly; but the only commercial transatlantic vessel that will accept pets is the Queen Mary 2. This ship cruises at least once a month between New York and Southampton, UK and further on to Germany.
This is a popular option for owners of snub-nosed breeds and other dog breeds that do not conform to airline pet policies or are at more significant risk due to breathing problems. The Queen Mary 2 books up fast, so pet owners should make their reservations as far in advance as possible.
This is an elegant ship and a stress-free way to travel for both you and your pet. Cunard offers spacious pet kennels and a full-time Kennel Master and assistant, who does nothing but make sure your pet is well cared for so you can relax knowing your pet is in good hands. Of course, there are generous visitations and exercise and play times as well.
Included are pet policies as well as all requirements for your pet to enter either the United States or the United Kingdom.
