This is a specific conversation about Senior dog food — what changes as they age — ask about yours and get one honest answer for your exact situation.

Living on a boat with a Labrador is a brilliant setup — but it does make the usual 'buy a 12kg bag and bung it in the cupboard' approach pretty much impossible. Senior dogs genuinely do need different nutrition as they age — typically lower calories to protect those joints, higher digestibility, and added glucosamine for a breed like a Lab that's prone to hip problems. But how urgently you need to switch depends on the dog's current health and what they're on now. What's your Lab's age and current food, and are there any health niggles I should know about — weight, joints, anything the vet's flagged?
He's 8, a big male Lab, about 36kg. He's been on Royal Canin Labrador adult but I've run out and can't keep buying the massive bags anymore. Vet mentioned last year his hips were starting to show early signs of wear but nothing serious yet. He's a bit chunky too, the vet said to watch his weight.

That's a really useful picture — thank you. At 8, a male Lab at 36kg who's already showing early hip wear and carrying a bit of extra weight is genuinely at the point where a senior formula makes sense. The two things you want from his food right now are: controlled calories to help shift that weight and reduce load on his hips, and added glucosamine and chondroitin to support the joints proactively. Given the storage constraint, can I ask — are you ordering online and having it delivered to a marina, or are you relying on what you can physically carry back to the boat? And is he a fast eater, any digestive sensitivity?
I can order online for marina delivery, that's fine. He's not sensitive, eats anything, but yes he hoovers it down. I just need smaller bags I can actually store in a locker.

Perfect — online delivery to a marina is the ideal solution here, and it means you've got good options. My recommendation is Hill's Science Plan Adult 7+ Large Breed dog food, and specifically to order it in the 2.5kg bags. Here's why it fits your exact situation: it's formulated for large senior dogs, so it has the reduced calorie density your Lab needs for weight management, plus glucosamine and chondroitin already built in for his hip concerns. Hill's large breed senior is also highly digestible, which matters as dogs age. The 2.5kg bags are compact enough to fit in a boat locker, and with a 36kg dog you're getting roughly 10–12 days per bag depending on serving size — so you order a couple at a time, they don't take over the boat, and you're never lugging a sack that weighs half as much as you do. It's available on Amazon UK with Prime delivery, which makes marina top-ups straightforward. The move from Royal Canin Labrador Adult is a sensible one at his age — the adult formula isn't calibrated for senior weight or joint needs the way this is.
That sounds really practical. How quickly should I transition him onto it?
inparticular.ai
Take about 7–10 days to transition, even though he's not sensitive. Mix roughly 25% new food with 75% old for the first few days, then 50/50 for a couple of days, then 75% new, then full switch. It lets his gut adjust and also means if he doesn't take to it immediately you're not throwing away a full bag. Labs tend to eat anything without drama, so you'll probably sail through it — but it's worth doing properly since you're also changing the nutritional profile, not just the brand. One other thing: with his weight, weigh his portions rather than using a cup measure. Hill's bags have a feeding guide by weight, and for a chunky Lab you'll likely want to feed at the lower end of the recommended range.
Really helpful, thank you. I'll order a couple of the 2.5kg bags now.

Good move — and worth checking that the listing specifically says Large Breed when you order, as Hill's 7+ comes in a standard version too and the large breed formula has the right glucosamine levels for a dog his size. A couple of bags should see you through three weeks or so, which is a sensible stock level for boat life. If his weight comes down over the next couple of months and his energy picks up, you'll know it's working. Good luck to both of you on the water.
