How to Stop Puppy Diarrhea

Updated July 19, 2017

“Diarrhea can be treated at home in the early stages, and if caught early, turned around. The key with diarrhoea is to stop it fast, before it turns into secondary diarrhoea with dehydration. Once the immune system is down, it is an invitation for other problems,” according to the Dog Breed Info Center website. Young puppies with diarrhoea usually need immediate medical attention; pups younger than four weeks of age can die from diarrhoea quite quickly. Consult with your veterinarian if your puppy’s diarrhoea is ongoing, unusual in appearance or is accompanied by other symptoms such as vomiting or fever.

  1. Fast your puppy, after consulting with your veterinarian, for 12 to 24 hours following the onset of his diarrhoea. Fasting gives his stomach and intestines a chance to recover.

  2. Provide extra water for your pet. Dogs, especially puppies, lose tremendous amounts of fluids rapidly with diarrhoea. The water helps to wash and clean out any irritants in his system.

  3. Give your puppy bland food following his fast. According to, a low-fat diet is best. For example, feed him boiled chicken or beef mixed with low-fat cottage cheese, boiled rice or potato. Give this to your puppy for three days, then gradually mix in his regular kibble over the next few days. As an alternative bland diet, purchase a prescription food from your veterinarian’s office.

  4. Add fibre to your puppy’s food if his stools are soft during or after his bland food stage. After consulting with your veterinarian, try Metamucil, between 1 ¼ teaspoon to 1 tablespoon per day for one to two days. The fibre helps draw water out of his stool, and its fermenting action in the colon helps your pup get back to normal.

  5. Give your puppy a pet store over-the-counter diarrhoea medication. These medications taste good and will soothe your pup’s irritation, discomfort and cramping. Consult with your veterinarian about administering Pepto Bismol (the pink liquid variety) as an alternative if your puppy is over six weeks old. Give him ½ to 1 teaspoon every three to four hours per every 4.54 Kilogram of his body weight.

  6. Talk to your puppy gently and spend extra time with him in order to reduce his stress. Nervous, upset or anxious pups are more prone to diarrhoea.

  7. Deworm your puppy, under your veterinarian’s guidance. Intestinal parasites often cause diarrhoea.

  8. Tip

    If your puppy is not drinking enough water, dehydration is a serious concern. Try adding an electrolyte solution to his water. He’ll probably like the taste and it will encourage him to drink more and replace lost minerals.


    If your puppy’s diarrhoea doesn’t improve within 24 hours or at any time is getting worse, take him to your veterinarian immediately. Also take action immediately if there is blood in his diarrhoea or he has other symptoms such as vomiting or fever.
