Sensitive stomach dog food for Weimaraners

A vet recommending a plain diet after repeated stomach upsets — without a specific diagnosis — is actually pretty common. It usually means they want to rule out ingredient-driven irritation before running more tests, which is sensible. The challenge is that 'plain diet' can mean a lot of things, and not all commercial sensitive-stomach foods are genuinely simple enough to make a difference. Sensitive stomach issues in dogs generally fall into a few categories — food intolerance, ingredient sensitivity, or a gut that just needs fewer variables — and figuring out which one applies to your dog shapes everything. To point you in the right direction: what breed and age is your dog, what symptoms have you been seeing most often, and what have they been eating up until now?

That's a really useful picture. A few things stand out. Weimaraners are a breed with a known tendency toward digestive sensitivity — their guts can be reactive to higher-fat foods and rich protein sources, both of which standard adult kibble like Pedigree often contains. At 8, he's also entering senior territory, and digestive efficiency does drop with age, meaning the same food that was fine at 3 can start causing issues by 7 or 8. The vet's instinct to go lower fat and simpler is right. Before I suggest anything — what protein has he been eating mostly? And has anything else changed recently, like routine, water source, or any treats or table scraps?

The Bakers treats are worth flagging — they contain artificial colours and a fairly long ingredient list, which can quietly aggravate a sensitive gut even if the main food is fine. Worth cutting those out or swapping to something single-ingredient while you settle his stomach. The dinner scraps are probably less of an issue in small amounts, but worth pausing for now just to isolate variables. On the food itself: chicken is a common sensitivity trigger in dogs that have eaten it for years — repeated exposure can build a low-grade intolerance even without a formal allergy diagnosis. Given his age, the fat sensitivity, and the likelihood of chicken intolerance, I'd move him to a food with a novel or hydrolysed protein, lower fat content, and a short ingredient list. The one I'd point you to is Purina Pro Plan Veterinary Diets HA Hypoallergenic dry food — it uses hydrolysed soy protein, which means the protein molecules are broken down small enough that the immune system typically doesn't react to them. It's genuinely low fat, highly digestible, and the ingredient list is about as simple as commercial dry food gets. It's available on Amazon UK and is exactly what a vet would reach for in this situation.

Fair question. If the hydrolysed route feels like a step further than you want to go right now, there's a solid mid-ground option: Purina Pro Plan Adult Sensitive Skin & Stomach with salmon as the protein source. It's a retail product — no prescription needed — but it's genuinely well-formulated. Salmon is a novel protein for a dog that's only ever eaten chicken, the fat content is moderate and well-controlled, and it's highly digestible. Purina's manufacturing standards for this line are unusually consistent, which matters because variation in kibble composition is a hidden cause of recurring symptoms. For an 8-year-old Weimaraner with the profile you've described, this is the food I'd start with. Transition slowly — about 10 days mixing old and new — cut the Bakers treats in the meantime, and hold the dinner scraps for a few weeks. You should see meaningful improvement in stool consistency within two to three weeks if ingredient sensitivity is the underlying issue.

A male Weimaraner typically sits between 30 and 35kg. At that weight, the Pro Plan Sensitive feeding guide puts a moderately active adult at roughly 300 to 340g per day, split across two meals. At 8, if he's slowed down at all — less running, more sleeping — lean toward the lower end. The bag has a guide, but the better indicator is his waist: you should be able to feel his ribs without pressing hard. Weight creep in older dogs can worsen digestive issues, so it's worth keeping an eye on. If symptoms haven't improved meaningfully after three weeks on the new food with treats cut out, that's the point to go back to the vet and push for a more specific workup — but most dogs with this presentation do respond well to a change like this.
