Occasional loose stools or vomiting after meals are common in dogs — but chronic digestive problems deserve attention and a proper dietary response. ‘Sensitive stomach’ is a catch-all term that describes several distinct conditions, each with different dietary solutions. This guide helps you understand which applies to your dog and what to feed them.
TYPES OF DIGESTIVE SENSITIVITY: 1. FOOD INTOLERANCE: Difficulty digesting a specific ingredient — most commonly high fat, certain proteins, or specific carbohydrates. Not immune-mediated. Managed by removing the trigger ingredient.
2. FOOD ALLERGY: Immune-mediated reaction to a protein. Causes GI symptoms plus often skin symptoms. Requires elimination diet to diagnose.
3. IBD (Inflammatory Bowel Disease): Chronic inflammation of the GI tract. Requires vet diagnosis (often biopsy). Managed with limited-ingredient, highly digestible diets.
4. EPI (Exocrine Pancreatic Insufficiency): Pancreas doesn’t produce enough digestive enzymes. Common in German Shepherds. Requires enzyme supplementation + highly digestible food.
5. Simple GI upset: Normal response to sudden food change, eating something inappropriate, or stress. Usually resolves in 24–48 hours.
WHAT TO LOOK FOR IN SENSITIVE STOMACH FOOD
✅ Single protein source (easier to identify and eliminate triggers)
✅ High digestibility (>85%) — look for named protein sources like egg, salmon, or chicken breast
✅ Moderate fat content (<15% DM) — high fat is the most common GI trigger
✅ Added probiotics/prebiotics (FOS, MOS, Lactobacillus strains)
✅ No artificial colours, flavours, or preservatives
✅ Limited ingredient formula — fewer ingredients = fewer potential triggers
❌ AVOID: Multiple unidentified protein sources | High fat content (>15% DM) | Complex formulas with 20+ ingredients | Artificial additives | Very high fibre (can worsen some conditions)

THE 7-DAY FOOD TRANSITION GUIDE
The most common cause of digestive upset in dogs is rapid food transition. Even moving to a better, more digestible food needs to be done gradually.
Day 1–2: 75% old food, 25% new food
Day 3–4: 50% old food, 50% new food
Day 5–6: 25% old food, 75% new food
Day 7: 100% new food
For dogs with known sensitive stomachs, extend this to 14 days:
Days 1–4: 75% old / 25% new
Days 5–7: 50/50
Days 8–11: 25% old / 75% new
Days 12–14: 100% new
If loose stools persist beyond day 7 despite gradual transition, the issue is likely the food itself (allergen or intolerance), not the transition speed.
Frequently Asked Questions
What should I feed a dog with a sensitive stomach?
Start with a single-protein, limited-ingredient, moderate-fat diet. Hills Sensitive Stomach (vet-backed), Advance Sensitive (AU-made), or Black Hawk Holistic Ocean Fish (single protein, grain-free) are our top OTC recommendations. If symptoms are chronic or severe, a vet check is warranted before assuming dietary management alone will resolve the issue.
How do I know if my dog’s stomach issues are from food?
Food-related GI issues typically occur within hours of eating and are consistent (not random). Environmental causes (stress, garbage eating, rapid eating) tend to be more episodic. If your dog has consistent loose stools or vomiting linked to meals, or if they have concurrent skin symptoms, food intolerance or allergy is more likely.
Is wet food better for dogs with sensitive stomachs?
Often, yes. Wet food has higher moisture content and is generally easier to digest than dense dry kibble. For dogs with confirmed GI sensitivity, a wet food diet or wet/dry mix often reduces symptoms. Hills Gastrointestinal wet (vet-prescribed) is the clinical standard for severe cases.
