Senior food for overweight Pugs with breathing issues

A ten-year-old Pug who's slowing down — that combination of age, weight, and breathing is really common in the breed, and it's genuinely worth getting the food right because those three things feed into each other. Senior dogs typically need fewer calories, better digestibility, and more joint support, but the right transition point and formula depends on the individual dog. Can you tell me roughly how much your Pug weighs right now, whether a vet has flagged anything specific like a heart check or mobility issues, and what you're currently feeding them?

Got it — 10.5kg with a 1.5kg to lose, brachycephalic breathing that's getting more noticeable on exercise, and currently on a standard adult dry. The weight is probably making the breathing harder, so that's the priority here. What I'd want in a food for him is a meaningful calorie reduction, good lean protein to preserve muscle as he loses weight, added glucosamine for his joints, and ideally smaller kibble that's easier to pick up and chew — Pugs can struggle with large pieces, which also affects how fast they eat and how much air they gulp. Has he had any digestive sensitivity on the Royal Canin, or does his stomach handle things fine?

That makes things easier. My recommendation is Hill's Science Plan Small & Miniature Senior Vitality, specifically the 7+ small and mini version. It's formulated for smaller senior dogs, so the kibble size works well for a Pug's short muzzle. Calorie density is notably lower than standard adult formulas — relevant for that 1.5kg you're working to shift — and it has added omega-3s, vitamin E, and glucosamine built in, which addresses the joint side of things as he's slowing down. The protein quality is good, which matters because you want him to lose fat, not muscle. It's widely available on Amazon UK, usually around £35–40 for a 6kg bag, which should last him a while at his recommended portion for weight loss. I'd drop about 10–15% off the back-of-bag guide amount and reassess at his next weigh-in in four to six weeks.

Honestly, the food won't fix the anatomy — brachycephalic airways are structural — but weight is one of the few things you can genuinely control, and carrying less will reduce the strain on his respiratory system meaningfully. A lot of Pug owners see a real difference in exercise tolerance once they hit a healthier weight. If the breathing seems laboured at rest, or he's making new noises, that's worth a vet conversation about whether there's anything soft-palate related going on. But based on what you've described — puffier on walks, otherwise fine — this is very typical for an older Pug and the weight loss is the right lever to pull first.

Good plan — transition over about ten days, mixing the new food in gradually, to avoid any stomach upset even if he's usually solid. Start with about 25% new food and work up. Given the weight goal, weigh him every three to four weeks rather than guessing by eye — Pugs carry weight in a way that's easy to miss until you actually check. You're doing the right thing catching this at ten rather than waiting.
