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.

Five dogs under one roof and one of them hitting senior status — that's a real logistics puzzle. Senior dogs genuinely do need something different: fewer calories, easier-to-digest protein, and ideally some joint support built in. The tricky bit isn't finding the right food for your Shih Tzu, it's feeding it to them without the other four crowding in. To point you in the right direction: how old is your Shih Tzu exactly, are there any health issues I should know about — weight, joints, digestion — and what are all five dogs currently eating?
She's 9, a Shih Tzu called Millie. She's been a bit slower on walks and her vet mentioned her joints at the last check-up. No other conditions. All five dogs are currently on the same adult dry food — a mid-range kibble — which is why it's easy, but the vet said Millie probably needs to move to something senior now.

That all makes sense. Nine is solidly senior for a Shih Tzu, and joint stiffness showing up at this age is very typical for the breed. What Millie needs now is a senior small-breed formula with controlled calories, good digestibility, and meaningful levels of glucosamine and chondroitin for her joints. I'd go with Hill's Science Plan Small & Mini Senior Vitality — it's specifically designed for small breeds from age 7+, uses high-quality protein, has omega-3s for mobility, and the kibble size suits a Shih Tzu perfectly. It's also widely available and consistent, which matters when you're managing a household of five. Now, for the feeding chaos: the simplest solution is to feed Millie separately in a different room or behind a baby gate at mealtimes. It takes about a week to become routine, and it means you don't have to switch all five dogs over — which would be unnecessary and more expensive.
That makes sense. Is it okay to just feed her separately every meal, or does that cause stress for her or the others?
inparticular.ai
It's absolutely fine — most multi-dog households feed dogs separately anyway, and dogs adapt quickly. If Millie is food-motivated, she'll actually love having her own space with no competition. The others may sniff around the gate for the first few days, but they settle. The only thing to watch is that none of the other dogs sneak into her bowl after she's done, since the senior formula won't harm a healthy adult dog occasionally, but you don't want them eating it regularly when they don't need the adjusted nutrient profile. Pick her bowl up as soon as she's finished and you're sorted.
Got it. And how do I transition her onto the new food without upsetting her stomach?
inparticular.ai
Standard transition over seven to ten days: start with about 25% Hill's mixed into 75% her current food, then go 50/50 around day four, then 75% new by day seven, and fully switched by day ten. Shih Tzus can have sensitive digestion, so don't rush it. If you see loose stools at any point, just hold at that ratio for an extra couple of days before moving forward. Given she's been on the same food for a while, going slowly is the right call.
Perfect, that's really helpful. I'll grab the Hill's and try the separate feeding setup this week.
inparticular.ai
That sounds like a solid plan. Hill's Science Plan Small & Mini Senior Vitality is available on Amazon UK if you want it delivered quickly. Once she's fully transitioned, give it six to eight weeks and you should notice her moving a bit more easily — the joint support takes a little time to build up. If her vet raises anything at the next check-up, Hill's is a brand most vets are happy to see on the food bowl, which makes that conversation easier too. Good luck with Millie and the pack.
