Home Remedies for Dog Diarrhoea: Safe Ways to Settle Your Dog's Stomach

Not every bout of diarrhoea requires a trip to the vet. Many cases of mild, acute diarrhoea in otherwise healthy adult dogs can be managed at home with simple dietary adjustments and careful monitoring. However, knowing the difference between a minor tummy upset and a medical emergency is critical.

"If your dog is bright, alert, still drinking water, and the diarrhoea has lasted less than 24 hours without blood, home care is a reasonable first step. But any signs of lethargy, bloody stool, or persistent vomiting alongside diarrhoea mean it's time for a vet visit." — Dr. Sarah Chen, DVM

Home remedies are suitable when your dog:

• Is an otherwise healthy adult (not a puppy, senior, or immunocompromised)
• Has had soft or watery stool for less than 24-48 hours
• Is still eating, drinking, and behaving normally
• Shows no blood or mucus in the stool
• Is not also vomiting repeatedly

If your dog shows any warning signs, consult our guide on when to worry about vomiting and diarrhoea or contact your vet immediately. Puppies, elderly dogs, and small breeds are at higher risk of dehydration and should be seen by a veterinarian sooner rather than later.

The cornerstone of home treatment for dog diarrhoea is the bland diet. This involves temporarily replacing your dog's regular food with easily digestible, low-fat ingredients that give the gastrointestinal tract a chance to recover.

Classic Bland Diet Recipe

The most widely recommended bland diet is boiled white rice with plain boiled chicken breast (no skin, bones, or seasoning). Mix in a ratio of roughly 2 parts rice to 1 part chicken. Serve at room temperature in small, frequent meals — 4 to 6 small portions throughout the day rather than one or two large meals.

Alternative Options

• Boiled sweet potato or white potato — mashed, plain, and cooled
• Plain canned pumpkin (not pumpkin pie filling) — 1-3 tablespoons mixed with rice. Pumpkin is rich in soluble fibre, which absorbs water and helps firm up loose stool
• Boiled lean turkey mince — a good alternative if your dog has a known chicken sensitivity
• Scrambled eggs — cooked without oil or butter, easy to digest and high in protein

Stay away from fatty foods, dairy, or anything on the toxic foods list. Even well-intentioned treats can irritate an already inflamed gut.

Transitioning Back to Normal Food

Once your dog has had firm stools for 24-48 hours on the bland diet, begin transitioning back to their regular food gradually over 3-5 days. Start with 75% bland / 25% regular, then shift the ratio daily until you're back to 100% normal food. A sudden return to regular food often triggers a relapse.

Dehydration is the single biggest risk when a dog has diarrhoea. Each loose stool pulls water and essential electrolytes out of the body, and small dogs can become dangerously dehydrated within hours.

Encouraging Water Intake

Always ensure fresh, clean water is available. Some dogs with an upset stomach become reluctant to drink, so try these strategies:

• Add a splash of low-sodium chicken broth (unseasoned, onion- and garlic-free) to their water bowl to make it more appealing
• Offer ice chips or ice cubes — some dogs find these easier to tolerate than gulping water
• Use a syringe — for very reluctant drinkers, gently syringe small amounts of water into the side of their mouth

Electrolyte Supplementation

For dogs with moderate diarrhoea lasting more than a few hours, an oral electrolyte solution can help replace lost minerals. You can purchase veterinary-specific electrolyte products (such as Oralade or Pet-A-Lyte) or make a simple home version:

• 1 litre of clean water
• 1 tablespoon of sugar
• 1 teaspoon of salt

Offer this alongside (not replacing) their regular water. If your dog refuses to drink for more than 8-12 hours, or if you notice signs of dehydration — dry gums, skin that doesn't snap back quickly when pinched, sunken eyes, or lethargy — seek veterinary care immediately. Severe dehydration often requires subcutaneous or intravenous fluids that can only be administered by a vet.

Probiotics are beneficial bacteria that support a healthy gut microbiome. During and after a bout of diarrhoea, the balance of bacteria in your dog's intestine is disrupted, and probiotics can help restore it more quickly.

Veterinary Probiotics

The most effective option is a veterinary-grade probiotic specifically formulated for dogs. Products containing strains like Enterococcus faecium, Lactobacillus acidophilus, and Bifidobacterium animalis have the strongest evidence base. Popular brands include FortiFlora, Proviable, and Pro-Kolin. These come in easy-to-administer sachets or pastes that most dogs accept readily.

Natural Probiotic Sources

• Plain, unsweetened yoghurt — a small spoonful (1-2 tablespoons depending on dog size) contains live cultures. Avoid yoghurts with xylitol, artificial sweeteners, or added sugars
• Kefir — plain, unsweetened goat's milk kefir is particularly well tolerated by dogs and contains a broader range of probiotic strains

Other Helpful Supplements

• Slippery elm bark — a natural demulcent that coats and soothes the intestinal lining. Mix 1/4 teaspoon per 10 kg of body weight with water into a paste
• Kaolin-pectin — an over-the-counter product that helps absorb toxins and firm up stool. Follow the dosage on the product label for your dog's weight

Important: Never give your dog human anti-diarrhoeal medications like loperamide (Imodium) without veterinary guidance. While sometimes used under vet supervision, it can be dangerous for certain breeds (especially Collies and related breeds with the MDR1 gene mutation) and can mask serious conditions that need treatment.

A short fasting period of 12-24 hours is sometimes recommended to give the gut a complete rest before starting a bland diet. This approach can be effective for healthy adult dogs with acute, uncomplicated diarrhoea.

How to Fast Safely

• Remove food but always keep water available — never withhold water
• After 12-24 hours, introduce the bland diet in very small portions
• Monitor energy levels closely throughout the fast

When NOT to Fast

Fasting is not appropriate for:

• Puppies under 6 months — they have limited energy reserves and can develop hypoglycaemia (dangerously low blood sugar) quickly
• Toy and small breeds — similarly at risk of blood sugar drops
• Senior dogs — they may not tolerate fasting well
• Dogs with diabetes or other metabolic conditions
• Dogs that are also vomiting — combined vomiting and diarrhoea increases dehydration risk significantly

For these groups, skip the fast and go straight to the bland diet in small, frequent meals. If you have a diabetic pet, always consult your vet before changing their feeding schedule — read more about managing diabetes in pets.

Home remedies have their limits. Recognising when it's time to escalate to professional care can be the difference between a quick recovery and a serious complication.

See your vet immediately if:

• Diarrhoea persists for more than 48 hours despite home treatment
• You notice blood or dark, tarry stools (haematochezia or melaena)
• Your dog is vomiting alongside diarrhoea and cannot keep water down
• There are signs of dehydration — dry gums, lethargy, loss of skin elasticity
• Your dog has a fever (normal temperature is 38.3-39.2°C / 101-102.5°F)
• Your dog is a puppy, senior, or has pre-existing health conditions
• You suspect your dog has eaten something toxic or a foreign object
• Your dog appears to be in pain — hunching, whimpering, or guarding the abdomen

Learning to recognise signs of pain in your dog is essential for every owner. Dogs are adept at hiding discomfort, so subtle changes in posture or behaviour can be important clues.

At the vet, expect a physical examination and possibly blood work, a faecal test, or imaging depending on the severity. Treatment may include prescription diets, anti-nausea medication, fluid therapy, or antibiotics if a bacterial infection is suspected. Most dogs with acute diarrhoea recover quickly with appropriate care — the key is not to delay when home remedies aren't working.
