Hydrolysed Dog Food: A Complete Guide for Dogs with Diarrhoea or Upset Tummy in the UK
When your dog has diarrhoea or an upset tummy, it’s stressful for both you and your pet. Digestive issues are one of the most common reasons dog owners visit the vet, and while mild cases often clear up quickly, persistent symptoms can signal food sensitivities or underlying health conditions.

One solution increasingly recommended by UK vets is hydrolysed dog food. In this guide, we’ll explain what hydrolysed dog food is, why it works, and how it can help dogs with diarrhoea or upset tummy.
What Is Hydrolysed Dog Food?
Hydrolysed dog food is a specially formulated diet designed for dogs with food allergies or chronic digestive problems. The key process is hydrolysis, which breaks down proteins into smaller fragments called peptides. These tiny molecules are less likely to trigger an immune response, making the food easier to digest and gentler on sensitive stomachs.
Why does this matter?
Dogs with diarrhoea or upset tummy often react to intact proteins in standard diets. Hydrolysed food reduces this risk, providing essential nutrition without irritation.
Why Dogs Develop Diarrhoea or Upset Tummy
Before switching diets, it’s important to understand the cause. Common reasons include:
- Food allergies or intolerances – Certain proteins or additives can inflame the gut.
- Sudden diet changes – Dogs thrive on consistency; abrupt changes can upset digestion.
- Stress – Anxiety can affect gut motility and cause loose stools.
- Underlying conditions – Pancreatitis, inflammatory bowel disease (IBD), or infections.
If diarrhoea lasts more than 24–48 hours, consult your vet. Chronic symptoms often require a tailored diet plan.
How Hydrolysed Dog Food Helps Ease Diarrhoea or Upset Tummies
Hydrolysed diets offer several benefits for dogs with diarrhoea or upset tummy:
- Gentle on digestion – Pre-broken proteins reduce strain on the gut.
- Minimises allergic reactions – Ideal for dogs with suspected food allergies.
- Supports gut health – Often enriched with fibre, omega fatty acids, and essential nutrients.
- Low-fat options – Beneficial for dogs prone to pancreatitis or fat-sensitive conditions.
When Should You Consider Hydrolysed Dog Food?
Hydrolysed dog food is often recommended when:
- Your dog has persistent diarrhoea or upset tummy despite standard care.
- Your vet suspects food allergies or IBD.
- You need a long-term hypoallergenic diet for digestive health.
Tip: Always transition gradually over 7–10 days to avoid further stomach upset.
