An upset stomach is one of the most common health complaints in dogs — and one of the most worrying for owners. Whether it's loose stools after a dietary change, occasional vomiting, or a dog that simply seems uncomfortable after eating, digestive issues are something almost every dog owner encounters at some point.
The good news is that many mild digestive upsets are short-lived and manageable at home. Understanding what's behind them — and having the right support to hand — makes a significant difference to how quickly your dog returns to normal.
Why Do Dogs Get Digestive Upsets?
Dogs have sensitive digestive systems that can be disrupted by a surprising range of everyday factors. Some of the most common causes include:
Dietary Changes
One of the most frequent triggers. Dogs' digestive systems are designed for consistency — switching foods too quickly, even to a higher-quality diet, can cause loose stools, gas and general discomfort. Any change in diet should ideally be made gradually over seven to ten days, mixing increasing proportions of the new food with the old.
Scavenging and Dietary Indiscretion
Dogs are opportunistic eaters. Raiding the bin, eating something on a walk, being given rich table scraps or over-indulging at Christmas are classic triggers for acute digestive upset. This type of upset is usually short-lived but can be quite dramatic in the immediate aftermath.
Stress and Anxiety
The gut-brain connection is well established in dogs as well as humans. Travel, kennelling, changes in routine, new pets or family members, or any situation that causes anxiety can manifest as loose stools or stomach upset. Stress-related digestive issues often resolve once the trigger is removed.
Infections and Parasites
Bacterial infections, viral gastroenteritis and intestinal parasites (worms, giardia) are all common causes of digestive upset in dogs — particularly in puppies or dogs with regular contact with other animals. These typically require veterinary diagnosis and treatment.
Food Sensitivities and Intolerances
Some dogs have ongoing sensitivities to specific ingredients — commonly certain proteins, dairy, wheat or artificial additives. Unlike acute upsets, food sensitivities tend to cause recurring or chronic digestive issues that only resolve when the trigger ingredient is identified and removed from the diet.
Eating Too Fast
Dogs that eat quickly swallow excess air alongside their food, leading to bloating, discomfort and sometimes vomiting shortly after meals. Slow-feeder bowls can help significantly for dogs prone to this.
Age-Related Changes
Older dogs often have less efficient digestive systems. Changes in gut motility, reduced enzyme production and age-related sensitivities can all contribute to more frequent digestive issues in senior dogs.
Signs Your Dog Has a Digestive Issue
Digestive upsets in dogs can present in a number of ways:
- Loose stools or diarrhoea — the most common sign; consistency and frequency matter when assessing severity
- Vomiting — occasional vomiting after eating is common; repeated vomiting is more concerning
- Flatulence — increased gas production, often accompanied by audible gut sounds
- Bloating or a distended abdomen — particularly important to monitor, as severe bloating can indicate a serious condition
- Loss of appetite — a dog going off their food for a day or two during a mild upset is common
- Lethargy — general low energy often accompanies digestive discomfort
- Grass eating — often a self-soothing behaviour when dogs feel nauseous or uncomfortable
- When to See a Vet
Most mild digestive upsets resolve within 24–48 hours with rest, a bland diet and appropriate support. However, some situations require prompt veterinary attention:
- Vomiting or diarrhoea lasting more than 48 hours
- Blood in vomit or stools
- Signs of significant pain, distress or a distended abdomen
- Lethargy combined with loss of appetite and digestive symptoms
- Suspected ingestion of a toxic substance or foreign body
- Puppies, senior dogs or immunocompromised dogs showing digestive symptoms — these groups can deteriorate more quickly
When in doubt, always consult your vet. Digestive symptoms can occasionally be the first indication of a more serious underlying condition.
How to Manage Mild Digestive Upsets at Home
For mild, short-term digestive upsets without any of the red flag signs above, home management is usually appropriate.
Rest the Digestive System
For a dog that has vomited or has loose stools, withholding food for 12–24 hours (while ensuring access to fresh water) gives the digestive tract a chance to settle. This isn't appropriate for puppies or very small dogs — consult your vet first if you're unsure.
Introduce a Bland Diet
After a rest period, reintroduce food gradually with something easy to digest — plain boiled chicken and white rice is the classic recommendation. Keep portions small and feed little and often for the first day or two before returning to normal food.
Keep Them Hydrated
Loose stools and vomiting can lead to dehydration, particularly in smaller dogs. Ensure your dog has constant access to fresh water and encourage drinking. If they seem reluctant to drink or show signs of dehydration (dry gums, lethargy, skin that doesn't spring back when gently pinched), seek veterinary advice.
Support with Gentle Herbal Care
Traditional herbal remedies have been used for centuries to support digestive comfort and healthy gut function — and a well-formulated herbal supplement can be a valuable part of home management for mild digestive upsets.

Longer-Term Digestive Health: Prevention Over Cure
For dogs that experience recurring digestive issues, a few ongoing habits make a meaningful difference:
Stick to a consistent diet — avoid frequent food changes and resist the temptation to supplement meals with table scraps or rich treats. Consistency is one of the single most effective things you can do for a dog prone to digestive sensitivity.
Feed at regular times — dogs thrive on routine, and regular mealtimes support consistent digestive function.
Transition foods slowly — any dietary change should happen over a minimum of seven days, gradually replacing the old food with the new.
Manage stress — if anxiety is a known trigger for your dog's digestive issues, addressing the underlying anxiety (with appropriate training, environmental adjustments or veterinary support) will also benefit their gut.
Keep up with parasite control — regular worming and veterinary-recommended parasite prevention is an important baseline for digestive health.
Monitor weight — both obesity and being underweight can affect digestive function. Regular weigh-ins and appropriate portion control help maintain optimal gut health.
