Senior dog food for sensitive stomachs

A dog who's had a reliable stomach for years and is now struggling in their senior years — that's a pattern I see fairly often, and it usually comes down to one thing: the digestive system becomes less efficient with age, and foods that were fine at three or five can start causing real trouble at twelve. Sensitive stomach issues generally fall into a few buckets — food intolerance, ingredient sensitivity, or a gut that simply needs a plainer diet — and working out which applies is how we find the right food. To point you in the right direction, it would help to know: what symptoms are you seeing — loose stools, vomiting, gas, something else — and what are you currently feeding, or what have you already tried switching to?

That makes a lot of sense. Pro Plan Adult is a decent food, but it's reasonably protein-dense and calorie-rich — perfectly fine for a younger dog but potentially more than an older gut can process comfortably. What you're describing — loose stools and post-meal vomiting, triggered especially by anything richer — is classic age-related digestive slowdown rather than a sudden intolerance. Her gut is likely producing fewer digestive enzymes than it used to, and it just can't handle the workload of a higher-fat, higher-protein adult formula. Before I suggest something specific: is she otherwise well in herself — good energy, drinking normally, no weight loss? And is the vomiting immediately after eating, or a bit later?

Good — that clinical picture is reassuring. Vomiting 20 to 30 minutes post-meal, combined with loose stools and sensitivity to richer food, but otherwise a bright and stable dog, points strongly to reduced digestive capacity rather than anything more serious. You don't need a prescription diet or anything elaborate here. What you do need is a food with a short, simple ingredient list, a single easily digestible protein source, lower fat content than her current food, and ideally some added fibre to firm up her stools. My recommendation would be Burns Penlan Farm Chicken and Rice dry food. It's a senior-friendly recipe made with a single protein source, low fat, very limited additives, and brown rice for gentle fibre. Burns is specifically designed around digestive simplicity — it's not marketed as a sensitive stomach food, but that's exactly what it delivers. Transition her slowly over about ten days, mixing it in gradually, and you should see a real difference within two to three weeks.

Dry is absolutely fine for a 12-year-old Jack Russell, especially one who's maintaining weight and has no dental issues that would make chewing difficult. The advantage of dry food here is consistency — portion control is easier, the recipes tend to be more stable batch to batch, and for a dog with a sensitive gut right now, fewer variables is genuinely helpful. If her teeth were a concern or she was losing weight, I'd say add some warm water to the kibble to soften it, which also slows down eating and can reduce that post-meal vomiting. But based on what you've described, Burns Penlan Farm dry is a solid call as a starting point.

Perfect. Do the ten-day transition, keep a rough note of how her stools are looking by week two, and if things haven't settled by week three it's worth a quick vet check just to rule out anything like low-grade pancreatitis, which can occasionally show up in older dogs with similar symptoms. But honestly, for a bright, stable dog whose digestion has simply changed with age, a simpler food is usually all it takes.
