Some dogs can go on cruises, but only dogs that are service animals or when on specific sailings on ships such as the Cunard's Queen Mary 2, which has dedicated onboard kennels.
Most of the major cruise lines ban dogs and other pets as a result of hygiene concerns and other regulations.
Although a few specialized dog friendly and multi night cruises are now emergency.
Traveler's on cruise ships with a service dog should also always confirm their cruise line's specific policies and documentation before booking the cruise.
If the dog is not a service dog or the cruise ship does not allow dogs you would have to make other arrangements for your dogs or other pets such as doggy daycare, pet sitters or have someone else simply care for the dog or pet while you're on your cruise.
Most of the major cruise lines, which include Royal Caribbean, Norwegian Cruise Line and Carnival cruise line allow for service dogs and service animals that are trained to perform specific tasks that are related to the person's disability.
And you may have to provide the cruise line with documentation and meet specific requirements, including immunization records.
And no emotional support animals are allowed as they must be service dogs and not just emotional support.
Cunard's Queen Mary 2 offers onboard kennels for pets on certain transatlantic crossings between New York and Southhampton.
Kennel space is also very limited and often needs to be booked up to a year in advance and you will often incur additional fees for pet accommodations, supplies and specialized care and be prepared for strict rules regarding your dog's location on the ship and their behavior.
