Most cruise lines do not allow pets on board, with one major exception
The short answer: almost no pets are allowed on cruise ships. The one exception is service animals — dogs trained to perform tasks for people with disabilities. Emotional support animals, comfort animals, and pets of any other kind are not permitted on any major cruise line sailing from U.S. ports.
This policy applies across Carnival, Royal Caribbean, Disney Cruise Line, Norwegian Cruise Line, and Princess Cruises. The restriction exists because ships have limited space, closed ventilation systems, and nowhere for animals to exercise or relieve themselves safely during multi-day voyages.
If you have a service dog, you will need to notify the cruise line before you book and provide documentation. If you have a pet you cannot leave behind, you have other options — but a cruise ship is not one of them.
Key Takeaways
- Service dogs trained to perform tasks for people with disabilities are the only animals allowed on cruise ships; emotional support animals are not.
- You must notify your cruise line in advance if you are traveling with a service dog and provide proof of the dog's training and your disability.
- Pets left at home should be cared for by a trusted person, a professional pet sitter, or a boarding facility — cruise lines do not offer pet care services.
- Some cruise lines offer pet-friendly hotels at their departure ports, which can help you arrange care before you board.
Service dogs are allowed; emotional support animals are not
A service dog is a dog trained to perform specific tasks related to a person's disability — tasks like guiding someone who is blind, alerting someone to a seizure, or retrieving items for someone with mobility limitations. Under the Americans with Disabilities Act (ADA), service dogs are not considered pets and must be allowed in public spaces, including cruise ships.
An emotional support animal is different. These animals provide comfort through their presence alone, but they are not trained to perform a specific task. Cruise lines do not recognize emotional support animals as service animals and will not allow them on board. The same applies to comfort animals, therapy animals, and any pet you want to bring for companionship.
If you have a service dog, contact your cruise line before you book. You will need to provide documentation showing the dog is trained to perform a task related to your disability. Most cruise lines ask for this information at least 48 hours before departure.
What documentation you need to bring for a service dog
Cruise lines do not require a specific government-issued service dog certificate, because no such certificate exists. Instead, you will need to provide proof that your dog is trained to perform a task related to your disability. This can include training records from the organization that trained your dog, a letter from your trainer, or documentation from your veterinarian.
You should also bring your own records showing the dog's vaccinations and health status. Cruise lines may ask to see proof of rabies vaccination and a recent health check. Keep these documents in your cabin during the voyage.
If you are unsure what your specific cruise line requires, call their disability services line before you book. Each line has slightly different procedures, and calling ahead prevents problems at the port.
Where to leave your pet while you cruise
If you have a pet that cannot travel with you, you have three main options: leave the pet with a trusted friend or family member, hire a professional pet sitter, or use a boarding facility.
A trusted person is often the simplest choice if you have someone nearby who knows your pet and can visit daily. Make sure they have keys, know your pet's routine, and have your veterinarian's contact information in case of emergency.
A professional pet sitter visits your home once or twice daily, feeds your pet, provides water, and lets them outside. Pet sitters typically cost $25 to $75 per visit depending on your location and the number of pets. You can find sitters through Rover, Care.com, or local pet care businesses.
A boarding facility keeps your pet overnight in a kennel or facility. Costs range from $30 to $100 per night for dogs, depending on the facility and your region. Some facilities offer play time, training, and grooming. Book boarding well in advance, especially during peak cruise season (winter and summer).
Pet-friendly hotels at cruise ports
Some cruise lines partner with pet-friendly hotels near their departure ports. These hotels allow you to stay the night before your cruise with your pet, then arrange boarding or a pet sitter for the duration of your voyage.
Carnival, Royal Caribbean, and Disney Cruise Line all list pet-friendly hotel partners on their websites. These partnerships do not mean the cruise line is boarding your pet — it means the hotel will accept your pet for the night, and you can arrange your own care from there.
This option works well if you are traveling from far away and do not want to rush to the port early in the morning. You can arrive the day before, spend the night with your pet, and then hand off care to a sitter or boarding facility before boarding the ship.
International cruises and pet restrictions
If you are taking a cruise that stops at international ports, pet restrictions become more complicated. Some countries have strict quarantine laws for animals entering their territory, even if the animal never leaves the ship.
For example, if your cruise stops in Canada, the Canadian Food Inspection Agency has rules about animals on vessels. If your cruise stops in the Caribbean, individual island nations may have their own regulations.
If you are traveling with a service dog on an international cruise, contact your cruise line at least two months in advance. They can tell you which ports have restrictions and what documentation you will need. You may need a health certificate from your veterinarian, proof of vaccinations, or other paperwork depending on where the ship docks.
What happens if you try to sneak a pet on board
Cruise lines have security screening at the port, and staff inspect cabins during the voyage. If a pet is discovered, you will be asked to disembark at the next port at your own expense, or the pet will be confiscated and held by port authorities. You will also forfeit your cruise fare and may be banned from future cruises with that line.
Beyond the cruise line's rules, bringing an undeclared pet across state or international borders can result in fines from the U.S. Department of Agriculture or local authorities. The risk is not worth it.
Frequently Asked Questions
Can I bring my emotional support dog on a cruise?
No. Cruise lines recognize only service dogs trained to perform specific tasks related to a disability. Emotional support animals, comfort animals, and therapy animals are not allowed. If your dog is trained to perform a task — such as alerting you to a medical condition or guiding you — it may may have access to as a service dog.
Do I need a service dog certificate to bring my dog on a cruise?
No official service dog certificate exists. Instead, you need documentation from your dog's trainer or veterinarian showing the dog is trained to perform a task related to your disability. Contact your cruise line before you book to find out exactly what they require.
What if my cruise stops at a port outside the United States?
Some countries have quarantine or import rules for animals, even if your pet never leaves the ship. Contact your cruise line at least two months before departure to learn what documentation you need. You may need a health certificate or proof of vaccinations from your veterinarian.
Can I leave my pet in my cabin while I go on shore excursions?
This is not an option because pets are not allowed on the ship at all. You must arrange care before you board — either with a pet sitter, boarding facility, or trusted person at home.
Are there any cruise lines that allow regular pets?
No major cruise line operating from U.S. ports allows pets other than service dogs. This includes Carnival, Royal Caribbean, Disney, Norwegian, and Princess. The policy is consistent across the industry.
