Introduction To Five Common Causes Of Diarrhea In Canines

There are many different diseases and conditions that can cause canine diarrhea. It isn’t a disease unto itself, but simply a symptom of an underlying problem. Severe cases of diarrhea can cause dehydration. If left untreated, this can be fatal. Keep reading to learn about five common causes of diarrhea in canines.


Giardia, a parasite that affects the intestinal tract, is one of the first common causes of diarrhea. Dogs can be infected with this parasite through contaminated water, food, or soil. An infected animal can also transmit the parasite through direct contact. It’s common for there to be no visible signs of an infection. However, dogs infected with giardia commonly experience diarrhea. It can range from mild to severe.


One of the next causes of canine diarrhea is parvovirus, a virus that usually affects younger dogs. An infection prevents your dog from absorbing liquids and nutrients from the food he eats. This happens because the virus damages the intestinal lining. Most dogs die when infected with the parvovirus. Severe diarrhea, bloody stool, and dehydration are common signs of an infection. Vaccination shots prevent this virus from affecting most adult dogs.


Diarrhea in canines can also occur because of hookworms or roundworms. Roundworms are intestinal parasites that usually infect puppies. Dogs with a roundworm problem will also experience stunted growth, vomiting, and a pot-belly. Roundworms can cause pneumonia, intestinal obstruction, or death if left untreated.

Hookworms affect dogs of any age. These worms attach to the intestinal lining and suck on blood. Puppies can even be infected before they’re born. If the hookworms are allowed to multiply unchecked, your dog may experience severe anemia.


Dogs can also suffer diarrhea because of distemper. This is an extremely serious disease that is highly contagious. The virus attacks the upper respiratory tract, intestinal tract, and brain. When the intestinal tract is affected, your dog will experience vomiting, dark diarrhea, coughing, and green discharge from the nose. The brain is affected in the final stages which leads to seizures. Dogs that do happen to survive a bout with this virus experience recurring nervous system problems in the future.


Dogs experiencing diarrhea may have ate something responsible for the problem. Eating human food is a common problem. Diarrhea may also develop if your dog’s diet changes suddenly. The good news is that diarrhea caused by food can usually be resolved within a day. You would have to give plenty of water and withhold food so the digestive system to correct itself.
