If your dog has frequent loose stools, gas, vomiting, or seems uncomfortable after eating, you’re not alone.
Sensitive stomachs are one of the most common concerns dog owners have, especially after switching foods, moving country, or introducing new treats.
The good news? Most stomach issues can be improved dramatically by choosing the right type of food and understanding what’s really happening inside your dog’s digestive system.
Let’s break it down properly.
How Do You Know If Your Dog Has a Sensitive Stomach?
Some common signs include:
Frequent soft stools or diarrhoea
Excessive gas
Vomiting after meals
Gurgling stomach sounds
Eating grass regularly
Reluctance to eat certain foods
Itchy skin alongside digestive issues
Occasional upset is normal. But if it’s happening often, food is usually a key factor.
Common Causes of Sensitive Stomachs in Dogs
1️⃣ Low-Quality Ingredients
Many commercial kibbles use:
“Meat and animal derivatives”
High ash content
Rendered meat meals of unknown origin
Artificial colourings and preservatives
Mixed meat sources and hidden fat sources (like random chicken fat) can cause irritation.
These can be difficult to digest and may irritate the gut lining.
2️⃣ Highly Processed Food
Traditional kibble is produced using extrusion, which involves very high temperatures and pressure.
This process can:
Denature proteins
Destroy some natural nutrients
Make the food expand in the stomach
For some dogs, especially those already prone to digestive sensitivity, this can cause discomfort.
3️⃣ Sudden Food Changes
Switching brands too quickly is a major cause of diarrhoea.
Dogs’ gut bacteria need time to adapt. A proper transition should take 7–10 days minimum.
4️⃣ Stress & Environmental Changes
Moving home (or country), heat, parasites, or routine changes can all disrupt digestion. If you're in Portugal, for example, parasites and heat stress can sometimes mimic food intolerance symptoms.
Ingredients That Often Trigger Digestive Issues
Not every dog reacts the same, but common triggers include:
Poor quality meat by-product meals
Artificial flavour enhancers
Excessive fillers (wheat, maize, soy in large quantities)
Very high fat levels
High ash content (over ~8–9% in dry food can be excessive)
The ingredient list tells you far more than the marketing on the front of the bag.

Ingredients That Support a Healthy Gut
If your dog has a sensitive stomach, look for:
✔️ Clearly Named Protein Sources
Example: “Chicken” or “Duck” rather than vague terms. Also try to focus on foods that have only one meat source/animal fat source to avoid potential triggers.
Most vets suggest a strict diet of rice and chicken for digestion issues, so that is a good place to start!
✔️ Moderate Fat Levels
Too high can cause loose stools.
✔️ Prebiotics
Such as:
FOS (Fructooligosaccharides)
MOS (Mannanoligosaccharides)
✔️ Gentle Fibre Sources
Pumpkin
Sweet potato
Brown rice
✔️ Cold Pressed Processing
Cold pressed food is made at much lower temperatures compared to extruded kibble.
This means:
Nutrients are better preserved
The food doesn’t expand heavily in the stomach
It breaks down more naturally during digestion
For many dogs with sensitive stomachs, this makes a noticeable difference.
Raw vs Kibble vs Cold Pressed for Sensitive Dogs
🥩 Raw Food
Can work very well for some dogs
Highly digestible when done properly
Requires careful balancing
Not always practical for travel or storage
🟤 Traditional Extruded Kibble
Convenient
Long shelf life
Can be harder to digest for sensitive dogs
🟠 Cold Pressed
Combines convenience with gentler processing
Often easier on digestion
Suitable for mixing with other feeding approaches
For many owners, cold pressed becomes a balanced middle ground.
When to See a Vet
Always consult a vet if your dog has:
Blood in stool
Persistent vomiting
Severe lethargy
Sudden weight loss
Symptoms lasting more than a few days
Food solves many problems — but not all.
A Quick Note From Experience
Many premium dog foods exist today, but the reason some brands focus so strongly on gentle digestion is because they were created for that exact purpose.
When food is designed around digestibility rather than mass production efficiency, sensitive dogs often thrive.
Final Thoughts
If your dog has a sensitive stomach, don’t just look for “sensitive” on the front of the bag.
Look for:
Ingredient transparency
Moderate fat levels
Digestive support
Gentler processing methods
The right food can transform your dog’s comfort, energy levels, and long-term health.
