About Diarrhea In Dogs

Read this page to learn about diarrhea in dogs, including the most common causes, plans of treatment, preventative measures and more.

Diarrhea in dogs can cause real problems for pets and pet owners alike. Diarrhea refers to the passing of watery stools, usually accompanied by an increased rate of defecation. This condition may arise by itself, but also may arise as a symptom of a bigger problem, which is why it’s often advisable to give your vet a call. Persistent diarrhea can lead to malnutrition and dehydration, particularly when accompanied with vomiting.


There are many different causes of diarrhea in dogs, the first and most common is to do with what your dog eats. Dogs often nibble at indigestible objects or eat things they find on the floor, including soil and the fecal matter of other animals. This in turn leads to irritation of the stomach and bowel.

Other causes may include infection with parasites (such as worms in dogs), viruses such as parvo and bacterial infections.

Symptoms of diarrhea in dogs

Diarrhea is a condition characterized by the passing of unformed stools, which will be liquid in appearance. Aside from this, your dog may become more thirsty due to the dehydration caused by this condition. The coloring will help you determine the problem:

Color Cause
Yellow/Green Rapid intestinal transit
Black Upper gastrointestinal tract bleeding
Red Lower gastrointestinal tract bleeding
Gray Poor digestion, diet too high in fat or grease

When accompanied by vomiting, it is a sign that your dog has eaten something which either can’t be digested, or was bacteria/virus contaminated. If you suspect bleeding, seek veterinary advice right away.


When diagnosing a dog with diarrhea, your vet may perform a food allergy test, to determine whether anything in your pet’s diet could be causing the issue. Your vet may also check for a bacterial infection, tumors, parasites, or malabsorption problems. In some circumstances, your vet may opt for an ultrasound test or colonoscopy.


You should follow the advice of your vet for treating diarrhea, as diarrhea may be one part of a separate illness. One medication which is sometimes used for the treatment of diarrhea in dogs is Pepto-Bismol for dogs.

Aside from this, you may need to make adjustments to your dog’s diet. Typically, diarrhea on its own may be treated by feeding your dog on a strict diet of chicken and white rice until the condition passes.


Dogs are natural scavengers, and when they nibble on the wrong things, they may end up contracting diarrhea. This includes toys. It’s a good idea to avoid giving your dog real bones, and instead opt for the use of nylon chew toy alternatives. You should also teach your dog not to eat things which he or she finds on the floor, be it indoors or out.

The use of Sentinel for dogs given once a month will help to prevent your dog becoming infected with parasites.
