Cunard Line and the Pet Policies, From their FAQ’s:
Are dogs welcome?
Queen Mary 2’s kennel programme is available on all Transatlantic Crossings between New York and Southampton in either direction, and is managed by a full-time Kennel Master who takes care of responsibilities such as feeding, walking and cleaning the ship’s 12 spacious kennels. Travelling dogs and cats also receive a complimentary gift pack. The kennels and adjacent indoor and outdoor walking areas are open throughout the day, enabling guests to spend significant time with their pets. Reservations for the kennels may be made at time of booking, and are based on availability. Contact Cunard for fees, details and additional requirements. All animals must be in compliance with the Pets Travel Scheme and in possession of a pet passport.
Are service animals/guide dogs welcome?
Cunard is pleased to permit individuals to bring service animals on board. You must provide notice of this at time of booking. Local laws or customs may prevent animals from disembarking at particular ports or countries. It is the guest’s responsibility to consult local customs authorities for requirements and to obtain all applicable documents and health certificates. Service animals are kept in staterooms with their owners. Non-service animals are only carried on QUEEN MARY 2 Transatlantic Crossings, in kennels, and are not allowed to visit any guest area of the ship.
