Independent scoring · Updated June 2026 · Not veterinary advice
A sensitive or upset stomach can have medical causes. Always speak to your vet before changing your dog's diet — especially for ongoing digestive issues, puppies, seniors or dogs with health conditions. Our scores reflect value, ingredients and transparency, not a clinical diagnosis.
Our top picks
Prime100
78Single-protein, limited-ingredient Australian range that does the elimination-diet job well and lists its ingredients clearly. The catch is cost: the rolls in particular work out expensive per kg for what's largely a simple recipe, and the sprawl of formats across air-dried, fresh and dry makes like-for-like value hard to pin down.
ZIWI Peak
81Genuinely high named-meat air-dried food with strong transparency — the ingredient panel is the real deal. But you pay heavily for it: among the highest price per kg and per serve in the category, and the value simply doesn't keep pace with the ingredient quality.
Hill's Science Diet
66A science-led brand with a deep, well-researched prescription range — clinically rigorous and consistent. Outside the therapeutic lines, though, the value is below average for the price: the standard panels lean on corn, grain and by-product meals rather than named single-source protein, and you carry a vet-clinic price premium for the brand and its shelf presence. The prescription range is the reason to buy it, not the everyday food.
Sensitive-stomach picks compared
What to look for
Single named protein
One clearly named animal protein (e.g. kangaroo, lamb) makes sensitivities easier to manage.
Limited ingredient
A short, transparent ingredient list reduces variables for sensitive dogs.
No unnecessary fillers
Avoid artificial colours and flavours and low-quality bulking fillers.
Complete & balanced
Confirm the food is complete and balanced for your dog's life stage.
Clear feeding guide
Transparent feeding guidance helps you get the portion and transition right.
Vet input first
For ongoing issues, choose the food with your vet — not from a list alone.

Frequently asked questions
For single-protein, limited-ingredient feeding, Prime100 is our standout. ZIWI Peak is excellent on ingredient quality with single-protein air-dried options, and Hill's Science Diet Sensitive Stomach is a solid non-prescription science-led choice. The right pick depends on your dog and budget — and on your vet's advice.
Look for a single, named animal protein, a short limited-ingredient list, no unnecessary fillers or artificial colours, and a clear, complete-and-balanced statement. Single-protein diets make it easier to identify what your dog tolerates, which is why they suit elimination feeding.
They often go together. A single-protein, limited-ingredient diet reduces the number of variables, which can help with food sensitivities and elimination trials. Prime100's single-protein rolls and dry ranges are built around exactly this.
Not always — many dogs do well on a good single-protein or limited-ingredient food. But persistent digestive issues can have medical causes, and some dogs need a therapeutic prescription diet. This is exactly the kind of decision to make with your vet, not from a comparison page.
No. This is especially important for sensitive stomachs: PetReviews is an independent value and comparison resource, not veterinary advice. Digestive problems can signal an underlying condition. Always speak to your vet before changing your dog's diet.
