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.

A 14-year-old Chihuahua with a poor appetite is a real balancing act — you need something calorie-dense enough that every small mouthful counts, but still gentle on an ageing gut. Senior dogs genuinely do need different nutrition: fewer empty calories, better digestibility, and usually more joint support. But the "senior" label alone doesn't tell you much — breed size, health history, and what they're currently eating all matter a lot. Can you tell me a bit more about her? What's she currently eating, and has the vet flagged anything specific — teeth, kidney function, anything like that?
She's 14, a female Chihuahua called Pip. She's always been fussy but lately she's barely touching her food. She's on Royal Canin Chihuahua Adult dry at the moment. Vet said her kidneys are fine, teeth are a bit worn but okay. She just seems to have lost interest in eating.

That's really helpful, thank you. Worn teeth and reduced appetite often go together in older small dogs — even if the teeth aren't obviously painful, the texture of dry kibble can put them off. And at 14, Pip's digestive system is less efficient too, so she needs more protein and fat per gram of food, not less. The good news on kidneys is that you don't need to restrict protein, which gives you more options. What I'd suggest is moving away from dry kibble entirely and switching to a high-quality wet food that's calorie-dense but easy to eat. Can I ask — does she show any interest when you offer her something soft or warm, like a bit of cooked chicken?
Yes actually, she goes for cooked chicken no problem. It's just the kibble she's ignoring.

That tells you everything. It's almost certainly the texture — and possibly the smell, since dry food loses aroma quickly. My clear recommendation for Pip is Hill's Science Plan Canine Mature Adult 7+ Small & Mini with Chicken in Sauce. It's a wet food designed specifically for small and toy breeds from age 7 onwards, so the portion sizes and calorie density suit a Chihuahua exactly. It's soft enough that worn teeth are no issue, highly digestible, and the chicken flavour tends to go down well with fussy eaters. The sauce adds moisture too, which matters for older dogs. Warm it slightly in a spoon of hot water before serving — that brings out the aroma and often makes the difference with a reluctant eater like Pip.
That sounds promising. Should I switch straight over or do it gradually?

Gradually is better even when a dog seems to be refusing their current food. Mix a small amount of the Hill's in with whatever she's willing to eat — even if that's just the wet food on its own at first — and increase it over about a week. This matters especially at her age because an older gut can react badly to sudden changes, even to something nicer. If after two weeks she's eating more consistently and her stools look normal, you're in a good place. If appetite still isn't improving, that's worth a vet follow-up — sometimes reduced appetite in very old dogs has an underlying cause like low-grade nausea or early dental pain that's easy to miss.
Really helpful, thank you. I'll give the Hill's a try.

Good luck with Pip — at 14 she's doing brilliantly. The main thing is getting calories into her reliably, and a soft, aromatic wet food is usually the answer at this stage. If the Hill's doesn't land, Royal Canin do a small dog ageing wet range that's worth trying as a backup. But start there and see how she responds.
