Spotting diarrhoea in your furry friend can be alarming, even when they appear to be their usual playful self. They’re eating with gusto, bounding around with tail-wagging joy, and showing no signs of distress. So—should you be concerned?
In short: yes, possibly. Occasional loose stools might not set off alarm bells, especially if your dog is still behaving normally. However, persistent or recurring diarrhoea—even in an otherwise lively pooch—can suggest that something deeper is going on. Understanding the causes and knowing how to respond is crucial for your dog’s health and comfort.
Let’s explore what might be going on, when to seek veterinary care, and how diet—especially sensitive stomach dog food—can play a significant role in managing your pet’s digestive health.

Why Would a Fit-Looking Dog Have Diarrhoea?
Dogs experience digestive upsets for many reasons, much like humans. While a single loose stool may simply reflect a minor disturbance, consistent or worsening diarrhoea should not be dismissed. Just because your dog acts fine doesn’t always mean everything is fine internally.
Some dogs have robust constitutions, masking symptoms better than others. That wagging tail may be concealing an inflamed gut or microbial imbalance. So, even when there’s no vomiting and energy levels are good, it’s worth looking deeper into potential causes.
Common Triggers for Diarrhoea in Otherwise Healthy Dogs
Here are some of the most frequent reasons your dog might be experiencing diarrhoea while still appearing normal:
1. Dietary Indiscretions
Dogs are natural scavengers. If your dog has recently had access to rubbish, leftovers, spoiled food, or unfamiliar table scraps, this can upset their stomach. Even something as simple as a lick of gravy or a bite of cheese can lead to loose stools.
2. Sudden Diet Changes
Changing your dog’s regular food too quickly can shock their digestive system. Dogs need time to adapt to new diets, and a gradual transition over 7–10 days is recommended to prevent gastrointestinal issues.
3. Food Sensitivities or Intolerances
Not all dogs digest the same ingredients equally. Some are sensitive to grains, dairy, certain proteins (like chicken or beef), or even additives and preservatives in lower-quality pet foods. These sensitivities can cause chronic or intermittent diarrhoea, often without other noticeable symptoms.
Many pet parents find success switching to hypoallergenic, novel protein, or vet-approved plant-based diets. Wet food options, with their higher moisture content, can be particularly gentle on sensitive tummies.
4. Stress or Emotional Upset
Believe it or not, your dog’s emotional state can affect their digestion. Major life changes—like a move, a new pet, or even guests visiting the home—can cause stress colitis, a condition where stress leads to temporary gastrointestinal upset. Excitement from travel or new environments can also trigger episodes.
5. Parasites
Worms (like roundworms or hookworms) and protozoa (like giardia or coccidia) can lead to diarrhoea even in dogs that otherwise seem fine. Puppies are particularly vulnerable, but adult dogs can also become infected, especially if they spend time outdoors or around other animals.
6. Mild Bacterial Imbalances
Dogs rely on a balanced gut microbiome—billions of beneficial bacteria that support digestion and immune health. Antibiotics, stress, or poor-quality food can throw this balance off, causing soft or frequent stools.
Does ‘Acting Fine’ Really Mean All Is Well?
Just because your dog is eating, playing, and behaving normally doesn’t mean you can rule out internal discomfort. Diarrhoea, after all, is your dog’s body attempting to expel something irritating or harmful.
Pay attention to subtle signs of trouble:
- More frequent or urgent trips outside
- Noisy tummy (gurgling or gas)
- Excessive licking of the rear end
- Slightly diminished appetite
- Presence of mucus or unusual color in stool
Mild diarrhoea may resolve on its own, but being observant can help you catch a bigger issue early.
When to Consult a Vet
In many cases, it’s safe to monitor your dog at home for 24–48 hours. However, veterinary advice should be sought if any of the following occurs:
- Diarrhoea persists for more than two days
- There’s visible blood in the stool
- Vomiting accompanies the diarrhoea
- Your dog becomes lethargic or loses interest in food
- Your dog is very young, old, or has an underlying condition
- Diarrhoea occurs frequently or in patterns (e.g., after eating)
Chronic or recurring diarrhoea could point to more serious conditions such as inflammatory bowel disease (IBD), pancreatitis, food allergies, or pancreatic insufficiency. Your vet may recommend blood work, stool analysis, or an elimination diet to diagnose the issue.
At-Home Care Tips for Mild Diarrhoea
For dogs who remain bright and lively, supportive at-home care can often help ease symptoms:
1. Temporary Fasting
Withhold food for 12–24 hours (only for adult dogs—puppies should not fast unless directed by a vet). This gives the gut a chance to rest and reset.
2. Keep Them Hydrated
Loose stools can lead to fluid loss. Make sure your dog has constant access to fresh water. You might also offer an unflavoured canine electrolyte solution if the diarrhoea is profuse.
3. Introduce a Bland Diet
After fasting, feed small portions of bland, easily digestible food. A common combo is plain boiled chicken (no skin, no seasoning) and white rice. Alternatively, many pet food brands offer bland diet formulas or sensitive stomach products designed for recovery.
Over the long term, consider feeding a diet specifically tailored for digestive health. Sensitive stomach dog foods often contain:
- Easily digestible proteins (like fish, duck, or plant-based)
- Added probiotics or prebiotics
- No artificial additives or by-products
4. Avoid Treats and Table Scraps
Stick to their main food while their gut stabilizes. Even a small snack can disrupt recovery if it contains allergens or hard-to-digest ingredients.
How to Prevent Future Upsets
Once your dog has recovered, consider taking proactive steps to prevent future tummy troubles:
- Feed a high-quality, consistent diet
- Transition slowly when changing food
- Keep garbage, toxic foods, and spoiled items out of reach
- Use regular parasite prevention and stool checks
- Avoid overuse of antibiotics unless necessary
- Incorporate vet-recommended prebiotics or fibre if needed
Dogs prone to sensitive stomachs often do best on simplified ingredient lists, limited-protein diets, or hypoallergenic meals. Brands like Omni Pet, which offer vet-formulated, plant-powered options, can be an excellent solution for ongoing digestive support.
Final Takeaway
While diarrhoea in a dog who’s otherwise acting fine may not indicate an emergency, it’s not something to ignore. Even in the absence of other symptoms, loose stools are a message from your dog’s body. It could be a fleeting incident, or it could point to food sensitivity, stress, infection, or a more persistent gastrointestinal condition.
Your best course of action is observation, hydration, and a return to dietary basics. If things don’t clear up within 48 hours—or if the issue returns—it’s time to call the vet.
And remember, prevention is key. Feeding a balanced, gentle, and appropriate diet can go a long way in keeping your dog’s digestive system running smoothly. For dogs with recurring tummy issues, sensitive stomach dog food from reputable sources like Omni Pet may help your dog thrive—inside and out.
Because when it comes to your dog’s health, peace of mind is priceless—and their wagging tail is always worth protecting.
