Diarrhoea is one of the most common digestive complaints in dogs, and it can be triggered by all sorts of things, from a sudden change in food to an infection, stress, or something they picked up mid-walk. A mild case will often clear up on its own, but persistent or severe diarrhoea can point to something more serious.

Knowing what's actually safe to offer, and what isn't, can make a real difference to how quickly and comfortably your dog recovers. Here's a practical guide to safe home remedies, the right foods to offer, and when it's genuinely time to see a vet.

Understanding Dog Diarrhoea

Normal dog stool is well-formed, moist but firm, and easy to pick up. Diarrhoea, by contrast, is loose, watery and often more frequent. An occasional soft stool usually isn't a concern, but ongoing diarrhoea can lead to dehydration, nutrient loss and intestinal inflammation.

Common causes include a sudden diet change or eating something inappropriate, like table scraps, rubbish or grass, food intolerances or allergies, stress or anxiety, bacterial, viral or parasitic infections, medication side effects (particularly antibiotics or NSAIDs), and chronic conditions such as pancreatitis, inflammatory bowel disease or liver problems.

Start by assessing how your dog seems overall. If they're alert, eating and drinking normally, gentle home care is usually reasonable. If they're lethargic, vomiting, refusing food, or you spot blood in the stool, call your vet straight away.

Home Care for Mild Diarrhoea

If your dog has mild diarrhoea but otherwise seems themselves, these steps are worth trying.

A short fasting period: withholding food, but never water, for 12 to 18 hours gives the digestive system a chance to rest and helps clear irritants. Avoid fasting puppies, small breeds or dogs with existing health issues without checking with your vet first.

Rehydration matters enormously: dehydration is a genuine risk with diarrhoea, so keep fresh water available at all times, and consider offering diluted, low-sodium chicken broth for flavour, or a vet-approved canine electrolyte solution.

A bland diet afterward: once the fast is over, offer small portions of something gentle, such as boiled white rice with plain chicken or turkey, boiled potatoes with no seasoning, or plain scrambled eggs as a mild protein source. Feed small, frequent meals, four to five times a day, and transition back to their regular food gradually over two to three days of improvement.

Extra digestive support: plain canned pumpkin, not pie filling, adds fibre that can help firm up stool. Probiotics and prebiotics restore healthy gut bacteria, and slippery elm powder or kaolin-pectin can soothe intestinal irritation. Introduce any of these gradually, and check dosages with your vet.

Over-the-Counter Options (Used With Caution)

A few over-the-counter products can help with mild cases, but they should only ever be used with veterinary guidance.

Kaolin-pectin mixtures can help thicken stool and soothe the intestinal lining. A typical dose runs around 1 to 2 mL per kilogram, up to four times a day, under vet guidance, and it shouldn't be combined with other oral medications, as it can reduce their absorption.

Bismuth subsalicylate, found in products like Pepto-Bismol or Kaopectate, can reduce inflammation and discomfort, and may temporarily turn the stool black. It should never be used without veterinary guidance, since dosing varies and an overdose can cause ulcers or toxicity.

Loperamide, found in Imodium A-D, slows intestinal movement and reduces stool frequency, but it can be genuinely dangerous for certain breeds, including Collies, Australian Shepherds and Old English Sheepdogs, due to a genetic sensitivity. Use only under veterinary supervision.

Supplements That Can Support Recovery

Probiotics and prebiotics support healthy gut bacteria and can shorten recovery time; look for dog-specific products containing Enterococcus faecium or Lactobacillus acidophilus.

Fibre supplements, such as psyllium husk or pumpkin purée, can bulk up stool and help normalise bowel movements. Start with small amounts.

Activated charcoal is sometimes used to absorb toxins in mild, food-related stomach upset, but only under veterinary guidance.

When to See the Vet

Not every case can be managed at home. Seek veterinary care immediately if your dog shows any of the following:

  • Blood or mucus in the stool
  • Vomiting, especially if it's persistent
  • Weakness, shaking or fever
  • Signs of dehydration: dry gums, sunken eyes, lethargy
  • Refusing food or water for more than 24 hours
  • Known ingestion of toxins, spoiled food or a foreign object

These can point to infections, parasites or underlying disease that genuinely needs medical treatment.

Veterinary Treatment Options

If your dog's condition doesn't improve within 24 to 48 hours, or gets worse, your vet may run diagnostic tests and recommend specific treatment.

Prescription medications can include metronidazole (Flagyl) for bacterial or inflammatory diarrhoea, tylosin (Tylan) for chronic or recurrent cases linked to bacterial imbalance, prednisone to reduce inflammation in chronic gastrointestinal disease (not for infections), and dewormers for parasitic causes such as roundworms, hookworms or giardia.

Vets may also prescribe a therapeutic diet: low-fat, highly digestible and nutritionally balanced to support gut healing.

Preventing Future Episodes

  • Avoid sudden diet changes; transition slowly over seven to ten days
  • Keep rubbish secure and skip the table scraps
  • Use parasite preventatives consistently
  • Provide clean, fresh water every day
  • Feed a high-quality, balanced diet suited to your dog's age and size
  • Manage stress through consistent routines and mental enrichment

If your dog has a history of sensitive digestion, ask your vet about a long-term probiotic or gastrointestinal support diet.

The Bottom Line

Mild diarrhoea in dogs is common, and it usually resolves with simple home care: hydration, rest and a bland diet. But if symptoms persist beyond two days, or come with vomiting, weakness or blood in the stool, see your vet without delay.

With the right care, observation and nutrition, most dogs bounce back quickly and comfortably from the occasional digestive upset.
