Most cases of mild dog diarrhea resolve within a day or two with a combination of gut rest, a bland diet, and simple natural supplements you likely already have at home. The key is reducing the workload on your dog’s digestive system while keeping them hydrated. Here’s how to do that effectively.
Start With a Short Fast
For adult dogs, withholding food for 12 to 24 hours gives the intestinal tract time to calm down. During this period, keep fresh water available at all times. Puppies, senior dogs, and small breeds shouldn’t fast for more than 12 hours because they’re more vulnerable to drops in blood sugar and faster dehydration.
Check for Dehydration
Diarrhea pulls water out of your dog’s body quickly, so monitoring hydration matters more than any supplement you’ll give. The simplest home test is the skin tent: gently pinch and lift the skin along the top of your dog’s head (between the ears, running front to back) for about two seconds, then release. In a well-hydrated dog, the skin snaps back flat almost immediately. If it stays tented or returns slowly, your dog has already lost a meaningful amount of body water.
You can also press a finger against your dog’s upper gum for a second, then release. The pale spot should return to pink within one to two seconds. A slower refill suggests dehydration is progressing. If you notice either of these signs along with lethargy or refusal to drink, skip the home remedies and call your vet.
Keep Fluids Up With Bone Broth
Plain water is essential, but many dogs with upset stomachs won’t drink enough of it. Bone broth works well because the flavor encourages drinking, and it delivers minerals like magnesium, calcium, and phosphorus that support hydration and muscle function. You can pour it over a bland meal or offer it on its own between feedings.
If you’re buying pre-made broth, check the label carefully. Many products marketed for humans contain onion, garlic, or high amounts of salt, all of which are harmful to dogs. Look for broths specifically made for pets, or make your own by simmering plain chicken or beef bones in water for several hours with no added seasoning.
Feed a Bland Diet
Once the short fast is over, introduce boiled chicken breast (no skin, no seasoning) mixed with plain cooked white rice. A common starting ratio is roughly one part chicken to two parts rice, though some dogs do fine with equal portions. Serve small meals, about a quarter of your dog’s normal portion size, three to four times throughout the day instead of one or two large meals. This keeps caloric intake steady without overwhelming the gut.
One thing to be aware of: some dogs quickly develop a preference for this home-cooked food and resist going back to kibble. That’s normal, and the transition section below covers how to handle it.
Add Pumpkin for Fiber
Plain canned pumpkin (not pumpkin pie filling, which contains sugar and spices) is one of the most widely recommended natural remedies for canine diarrhea. The soluble fiber absorbs excess water in the intestines, helping firm up loose stools. It also acts as a gentle prebiotic, feeding beneficial gut bacteria.
The American Kennel Club suggests adding 1 to 4 tablespoons per meal, scaling up based on your dog’s size. A small dog under 20 pounds does well with 1 tablespoon, a medium dog with 2, and a large breed with 3 to 4. Mix it directly into the bland diet. Most dogs enjoy the taste, so getting them to eat it isn’t usually a battle.
Try Probiotics
Probiotics introduce beneficial bacteria that help restore balance in the gut. A study on puppies with acute diarrhea found that a multi-strain probiotic containing Lactobacillus and Bifidobacterium strains reduced symptoms in nearly half the dogs within 24 hours of the first dose. By 72 hours, over 83% had fully resolved stools. While this particular study focused on very young puppies, probiotic strains from these same bacterial families are the active ingredients in most canine probiotic products sold today.
Look for a pet-specific probiotic rather than giving your dog a human supplement. Pet formulas are dosed appropriately and often contain strains like Enterococcus faecium that have been studied specifically in dogs. Powdered versions that you sprinkle over food tend to be easier to administer than capsules.
Slippery Elm Bark as a Gut Soother
Slippery elm bark is an herbal remedy that forms a gel-like coating when mixed with water. This coating lines the intestinal walls, reducing irritation and helping protect inflamed tissue. It’s been used in both human and veterinary herbal medicine for decades.
The typical dose is about a quarter teaspoon of powdered slippery elm bark per 10 pounds of body weight. Mix it with a small amount of cold water to form a thin paste, then add it to your dog’s food or syringe it directly into their mouth. If you have capsules, use half a capsule per 10 pounds, opened and mixed with water the same way. Dogs under 10 pounds can still use the quarter-teaspoon dose safely.
Transition Back to Normal Food Gradually
Once your dog has had normal, firm stools for at least 24 hours, you can begin reintroducing their regular food. Don’t switch back all at once. Start by replacing about a quarter of the bland diet with your dog’s normal kibble or food. Each day, increase the proportion of regular food while decreasing the bland mix. Over the course of four to five days, you’ll be back to 100% normal diet.
If stools soften again during the transition, drop back to the previous ratio for another day or two before trying to advance again. Some dogs need a slower transition than others, especially if their diarrhea lasted more than a couple of days.
Signs That Need Veterinary Attention
Natural remedies work well for mild, short-lived episodes, but certain signs indicate something more serious is going on. Cornell University’s veterinary guidance is clear on when home care isn’t enough:
- Duration beyond 48 to 72 hours. If a bland diet and supportive care haven’t improved things within two to three days, the cause likely needs professional diagnosis.
- Black or tarry stools. This color comes from partially digested blood higher up in the digestive tract and signals internal bleeding.
- Fresh red blood in the stool. Small streaks can happen with irritation, but consistent or large amounts need evaluation.
- Vomiting alongside diarrhea. The combination accelerates dehydration dramatically and makes it nearly impossible for your dog to absorb nutrients or fluids.
- Loss of appetite or lethargy. A dog who refuses food entirely or seems unusually tired is telling you they feel significantly unwell.
Puppies, elderly dogs, and dogs with existing health conditions have less margin for error. For these dogs, even 24 hours of persistent diarrhea warrants a call to your vet rather than waiting to see if things improve on their own.
