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.

Running four dogs at different life stages is a real logistical puzzle, especially when one of them is a senior who genuinely needs something different on the plate. Senior dogs typically need fewer calories, easier-to-digest protein, and more joint support — but the right moment to switch and exactly what to switch to depends a lot on the individual dog. To point you somewhere useful: what breed and age is your senior, do they have any health conditions going on, and what are all four dogs currently eating?
The senior is a 10-year-old Miniature Schnauzer called Biscuit. He's otherwise healthy but starting to slow down a bit and has put on a little weight over the last year. The other three are a 2-year-old Labrador, a 5-year-old Border Collie, and a 6-month-old Cockapoo puppy. They're all currently on the same adult kibble which I know probably isn't ideal. It's just been easier to manage.

Totally understandable — four dogs, four different needs is genuinely hard. The good news is Biscuit is the one who needs the most specific change right now. At 10, Miniature Schnauzers are firmly in senior territory, and the weight creep you're describing is classic for the breed at this age — their metabolism slows and they hold onto calories more efficiently. The adult kibble the others are on is almost certainly too calorie-dense for him. Before I suggest anything specific, a couple of quick questions: is Biscuit showing any joint stiffness or mobility issues, and roughly how much does he weigh at the moment?
He's about 9.5kg so slightly over where he should be. No obvious joint issues yet but he's definitely less bouncy on walks. No other diagnosed conditions.

That's really helpful. Slightly overweight, energy dipping, no joint diagnosis yet but early signs of slowing — this is exactly the profile where getting the food right now makes a real difference before problems develop. For Biscuit specifically, I'd go with Hill's Science Plan Mature Adult 7+ Small & Mini. It's formulated specifically for small and miniature breeds from age 7 onwards, has controlled calories to support healthy weight, and includes omega fatty acids and glucosamine to get ahead of joint issues before they become a problem. Critically for your situation, it's a dedicated small-breed senior formula, which means you can feed it to Biscuit separately without the others being tempted to steal it — the kibble size and smell profile is noticeably different from most adult foods. The main practical change is just feeding Biscuit in a separate room or with a door between him and the others at mealtimes, which many multi-dog households find easier than it sounds once it's routine.
That makes sense. Is it hard to find or expensive compared to regular food?

It's widely available on Amazon UK and through most pet retailers — not a specialist hunt. Price-wise it's mid-range, a little more than basic supermarket food but less than prescription diets. For a Schnauzer at Biscuit's size you're looking at a 3kg bag lasting around six to eight weeks depending on portions, so the ongoing cost is pretty manageable. The bigger win here is that getting his weight back to around 8–8.5kg over the next few months will take pressure off his joints and likely put some of that bounce back in his walks.
Brilliant, that's really clear. I'll order a bag and introduce it gradually. Thanks.

Good plan — transition over 7 to 10 days mixing increasing amounts of the new food into the old, which keeps his digestion happy. If his weight isn't shifting after six to eight weeks on the right portions, it's worth a vet check just to rule out thyroid issues, which Schnauzers can be prone to. But start with the food and you'll very likely see a difference.
