A 14-year-old Chihuahua losing weight and going off food is something worth taking seriously — appetite changes and gradual weight loss at that age can have several causes, some of which genuinely need a vet to rule out before nutrition alone can help. Has your little one had a check-up recently? And can you tell me a bit more — is she turning her nose up at food she used to love, eating smaller amounts, or skipping meals entirely? Knowing that helps me point you in the right direction.
She saw the vet about six weeks ago and everything came back fine — teeth, bloods, the lot. The vet said she's just getting old and to try tempting her with something more palatable. She used to wolf down her food but now she picks at it. She's gone from 2.8kg down to about 2.4kg over the last few months.

That's really helpful — and honestly reassuring that the vet has already cleared the obvious medical causes. A 400g drop on a Chihuahua is significant proportionally, so you're right to act on it. The issue with many senior small-breed foods is that they're lower in calories to prevent weight gain, which is exactly the wrong direction for a dog who's already losing weight. What is she currently eating — wet food, dry, or a mix?
She's been on dry kibble her whole life, a generic supermarket senior brand. I tried adding warm water to it to make it softer and she ate a bit more, but not loads.

The warm water trick is a good instinct — it releases the aroma and makes it easier to chew, which matters more as dogs age. But a generic supermarket senior kibble is likely working against you here. They tend to be bulked out with fillers, which means she fills up before getting enough calories or protein. At 14, she needs higher-quality, easily digestible protein to hold onto muscle mass, not less of it. My recommendation is Royal Canin Chihuahua Adult 8+ — it's breed-specific, designed for the Chihuahua jaw and bite size, and formulated with older small dogs in mind. It supports muscle maintenance, has an adapted calorie density that won't under-fuel her, and most importantly, small breeds tend to find it genuinely palatable. It's not cheap, but for a dog her size the bag lasts a long time and the quality jump over supermarket food is real. I'd still keep adding a splash of warm water, and if she's really reluctant some days, a teaspoon of low-salt chicken broth over the top can make a big difference.
That makes a lot of sense. Should I be adding any supplements on top of that, or is the food enough?

If you switch to the Royal Canin 8+ and she starts eating it properly, I'd honestly hold off on supplements to begin with — adding multiple things at once means you don't know what's helping if she improves. The one exception I'd consider is a small amount of omega-3 fish oil, which supports joint comfort and coat condition in older dogs and is very well tolerated. A half-capsule of a standard 1000mg human fish oil capsule squeezed over her food a few times a week is fine at her size. But get the food sorted first — that's doing the heavy lifting.
Perfect, that's really clear. I'll order the Royal Canin tonight. Thank you so much.

You're very welcome. She's lucky to have someone paying this much attention at 14 — that kind of careful monitoring is exactly what keeps senior dogs comfortable. Keep an eye on her weight over the next four to six weeks; if she stabilises or starts creeping back up you'll know the switch is working. And if the weight loss continues despite good eating, go back to the vet — sometimes a six-week-old blood panel is worth repeating. Good luck to you both.
