Marine-grade dog crate for ferry travel

A rusted-shut crate door after a ferry crossing is a genuinely dangerous situation — and a frustrating one when you've invested in what looked like decent kit. Standard steel hardware on most travel crates simply isn't rated for prolonged salt air exposure, and bulldogs make this worse because they're heavy, powerful dogs who'll lean into a door that isn't opening easily. Before I point you toward something that'll actually hold up, tell me: how old is your bulldog and roughly how much does he weigh? And are ferry crossings your regular travel method, or do you also need this crate to work for car journeys or flights?

25kg is on the heavier end for a bulldog — they're dense dogs. Dover-Calais is short but the salt spray exposure on an open car deck is brutal, and most crate manufacturers simply don't test for it. For car and ferry use with a dog that size, I want to know one more thing: are you crating him in the car boot, or does he travel on a seat? And does he tend to be calm in a crate, or does he push and pace?

Classic bulldog is right — that initial door-shoving is exactly what breaks poorly made latches over time, and salt corrosion on top of mechanical stress is what seized yours. For your situation, I'd go with the Ruffland Kennel in the large size. It's a rotomolded plastic shell with stainless steel hardware throughout — no painted steel, no zinc-plated hinges that corrode. The door latch is a positive-lock system that handles repeated pressure well, which matters for a dog who tests it every journey. The plastic body won't rust or corrode regardless of what the ferry deck throws at it, and it's ventilated on four sides which is important for a brachycephalic breed like a bulldog — they need airflow. It fits cleanly in an estate boot and is approved for airline hold use too, so you have flexibility if that ever changes. It's not cheap, but it's the only crate I'd confidently recommend for regular marine environment use.

Good question to push on — bulldogs are deceptive because they're not tall but they're very wide through the chest and shoulders. The Ruffland Large has an internal width of around 56cm, which accommodates the bulldog build well. The measure that matters most is that your dog should be able to stand without his head touching the roof and turn around comfortably — at 25kg and typical bulldog proportions, the large hits that. If he's unusually stocky or you want more confidence, Ruffland also do an XL, but most bulldogs fit the large without it feeling excessive. I'd cross-check against his chest width if you can measure it, but large should be your starting point.

Good — and when it arrives, give the door latch a few dry runs before the first trip so he can get used to the sound of it. Bulldogs tend to settle faster when the crate smells familiar, so a blanket or toy from home in there from day one helps too. Safe travels to both of you.
