Before choosing a sailing because the time looks perfect, check what the operator actually allows for dogs on that ship.
Sort the paperwork before the timetable
Pet travel documentation and health rules can change. Check current official requirements and the ferry operator's instructions before you book, especially if you are travelling internationally.
What will your dog actually do onboard?
This depends on the ship and sailing. Ask whether your dog stays in a vehicle, in a kennel or in pet-friendly accommodation, and what access you will have during the crossing. Don't assume the arrangements are the same on every ferry.
Pack the dog bag too
A lead, water, bowls, necessary medication and documents should be easy to reach. Think through exercise and comfort breaks around the port's check-in and arrival procedures.
