Dogs will often experience a stomach upset at some point in their lives. Seeing your dog vomit, develop diarrhoea or suddenly refuse food can feel worrying, especially if they normally have a healthy appetite.
In many cases, digestive issues are short-term and settle within a day or two. A dog’s digestive system is sensitive and reacts quickly to changes in food, environment or routine. However, ongoing or repeated symptoms can indicate that the gut needs more support.
Understanding what signs to watch for, and how to respond calmly, can help you keep your dog comfortable while recognising when veterinary advice is needed.
Why Dogs Get Digestive Upset
Dogs experience the world through their nose and mouth. Unlike people, they do not always distinguish between food and non-food items, and they often eat quickly without chewing thoroughly.
Because of this, their stomach frequently encounters things it is not prepared to digest.
Even positive changes, such as a new food you hope they will enjoy, can temporarily disturb the balance of bacteria in the gut.
Dogs also have a shorter digestive tract than humans. Food moves through more quickly, meaning there is less time to adjust to unfamiliar ingredients. This is why consistency is so important for digestive health.
Common Causes Include:
Eating spoiled food or rubbish outdoors
Sudden changes in diet
Rich treats or table scraps
Food sensitivities
Stress or excitement
Parasites
Mild infections
Overeating
Signs Your Dog May Have A Digestive Problem
Digestive upset can appear suddenly or gradually. Some symptoms are obvious, while others are small behavioural changes owners often notice first.
Vomiting
An isolated episode may happen if a dog eats too fast, consumes grass or irritates the stomach. Repeated vomiting, however, suggests the stomach is struggling and should be monitored carefully.
Diarrhoea or Soft Stools
Loose stools are very common and often appear quickly after a dietary indiscretion. You may also notice urgency, increased frequency or accidents indoors.
Loss of Appetite
Many dogs refuse food when they feel nauseous. A normally enthusiastic eater turning away from their bowl is often one of the earliest warning signs.
Lethargy
Dogs with digestive discomfort may seem quieter than usual, sleep more or show less interest in walks and play.
Other Changes You Might See
- Excessive gas
- Stomach gurgling noises
- Restlessness and being unsettled at night
- Lip licking or excessive drooling
- Eating grass
- Changes in stool smell or colour
These signs occur because the digestive tract is irritated and working harder than normal.
How To Help Your Dog At Home
If your dog is bright, alert and symptoms are mild, simple supportive care is often enough while the stomach settles.
Allow The Stomach To Rest: For adult dogs with mild vomiting, removing food for around 8-12 hours can help calm irritation. Puppies should not be fasted and should be monitored closely.
Feed Them A Gentle, Bland Diet: Offer small portions of easily digestible foods such as: boiled chicken (skin removed), plain white fish, or white rice. Feed little and often rather than giving a full meal.
Keep Hydration A Priority: Provide constant access to fresh water. Small frequent drinks are easier on the stomach than large amounts.
Reduce Activity Temporarily: Excitement, running and treats can prolong digestive upset. Quiet rest supports recovery.
If symptoms improve, gradually reintroduce your dog’s normal food over several days rather than changing back immediately.
How Can Hydrolysed Food Support Dogs With Digestive Issues?
Our hydrolysed dog food range is specially formulated for dogs with diagnosed food allergies or severe sensitivities. These diets use hydrolysed proteins that are broken down into smaller components, making them far less likely to trigger an immune reaction while remaining highly digestible.
Often used as part of a veterinary-guided elimination diet, hydrolysed recipes can help manage chronic digestive issues, skin conditions and food intolerance while still providing complete and balanced nutrition. You can explore our full hydrolysed dog food range to find the best solution for your dog.

How Does Hypoallergenic Dog Food Help With Digestive Issues?
Our hypoallergenic dog food range is designed to reduce the likelihood of food-related sensitivities by avoiding common allergens such as wheat, dairy, soy and beef. Instead, these recipes use carefully selected alternative protein sources and limited ingredient formulations to support dogs with skin irritation, digestive discomfort or suspected food intolerances.
Formulated to be gentle on both the skin and digestive system, these diets provide complete, balanced nutrition while helping manage symptoms such as itching, ear infections and stomach upset linked to food sensitivities.
When To Contact Your Veterinarian
While many stomach upsets are mild, some situations require prompt veterinary care. Contact your vet if you notice:
Symptoms lasting longer than 24–48 hours
Repeated vomiting
Blood in vomit or stools
Refusal to drink
Marked lethargy or weakness
Abdominal swelling or pain
Symptoms in puppies, senior dogs or dogs with existing illness
Veterinary support may include medication, fluid therapy or a specially formulated highly digestible diet to allow the gut to recover safely.
The Role Of Nutrition In Digestive Health
The digestive tract relies on stable, predictable nutrition. Sudden dietary variation is one of the most common triggers of recurring stomach upset.
Helpful feeding practices include:
- Consistent mealtimes each day
- Gradual food transitions over 7-10 days
- Avoiding rich human foods
- Appropriate portion sizes
- Easily digestible protein sources
Supporting the natural gut bacteria also helps maintain stool quality and nutrient absorption.
Preventing Future Digestive Issues
Although not all stomach problems can be avoided, you can significantly reduce the likelihood by:
- Preventing access to bins and scavenging
- Limiting treats and table scraps
- Maintaining routine parasite prevention
- Keeping feeding schedules consistent
- Avoiding frequent diet changes
- Ensuring constant access to fresh water
Dogs thrive on routine, and their digestive system does too.
