This is a specific conversation about Dog food for sensitive stomachs — ask about yours and get one honest answer for your exact situation.

A 15-year-old Dachshund is at a stage where the digestive system really has thinned out its reserves — slower gut motility, reduced enzyme production, and less tolerance for anything rich or complex are all normal at that age. Sensitive stomach issues in dogs generally come down to food intolerance, ingredient sensitivity, or a gut that simply needs a plainer, more digestible diet, and in a dog this senior it's almost always that third category. To point you in the right direction: what symptoms are you seeing — loose stools, vomiting, gurgling, gas? And what has she or he been eating up to now?
She's 15, a miniature Dachshund called Peggy. She's been getting loose stools most days for a few months, sometimes with a bit of mucus. She's also gassy and just looks uncomfortable after eating. She's been on the same senior dry food for a couple of years but it doesn't seem to be agreeing with her anymore.

That pattern — mucus in the stools, gas, visible discomfort after meals — is very typical of a senior dog whose gut has just lost the ability to handle a diet that was probably fine a year or two ago. At 15, the intestinal lining is less robust, digestive enzymes are less efficient, and fat tolerance in particular drops. The first thing to do is move her to something with a single, lean protein source, highly digestible carbohydrates, and added prebiotics or beet pulp to firm up those stools. What's the current food she's on, and is she on any medication or supplements?
She's on a supermarket own-brand senior dry food — I honestly just kept rebuying it out of habit. She's on a joint supplement but nothing else. She has a vet check next week so I'm not looking to replace the vet's advice, just want to go in with a better idea of what to try.

That makes complete sense, and going to the vet with a specific food in mind is a good approach. The supermarket senior foods tend to have higher fat levels and mixed protein sources than a dog like Peggy needs right now — that's likely a big part of what's driving the loose stools and gas. For a 15-year-old with these exact symptoms, I'd recommend Hill's Science Plan Adult Sensitive Stomach & Skin dry food — specifically the small and mini breed version. It uses chicken as a single primary protein, has a controlled fat level, and is built around highly digestible ingredients with prebiotic fibre to support gut motility. It's clinically backed, widely recommended by vets for sensitive senior dogs, and very easy to find. The kibble size also suits a miniature Dachshund well. Transition slowly — about ten days mixing old and new — to avoid making the loose stools worse in the short term.
That sounds really sensible. Is dry food definitely better than wet for her at this age, or should I be thinking about switching to wet?

For Peggy specifically, wet food is worth seriously considering as a complement or even a full switch. At 15, dental wear often makes dry kibble uncomfortable, and wet food is naturally easier to digest because of its higher moisture content — that hydration also supports kidney function, which is a real concern in very senior dogs. If she's eating the dry food fine physically, you could stay with it or mix in a wet option. Hill's also does a wet sensitive stomach range that pairs well. Mention the wet versus dry question to your vet next week too — they'll be able to check her teeth and kidney values and give you a direct steer.
Really helpful, thank you. I'll pick up the Hill's before her appointment so I can mention it.

Good plan. Hill's Science Plan Sensitive Stomach & Skin small and mini breed is the one to go for — it's on Amazon UK and most pet retailers. Take note of the current food's ingredients when you go to the vet too, as that context will help them give you a sharper recommendation. Peggy's lucky to have someone paying this much attention at 15.
