Hidden reasons your dog has diarrhea

Pets Uniq has researched and talked to several vets all over the country. Following are the 10 reasons why your canine must have diarrhea:

A change in diet

Suddenly changing your pup’s diet can cause diarrhea. Dogs have tiny and sensitive stomachs. Therefore, they cannot handle sudden changes. You should slowly change their diet to give them ample time to adjust. Mix new dog food in their previous dog food. Gradually increase the quantity of new dog food and decrease the amount of old dog food. Add canned pumpkin to their diet. Canned pumpkin regulates digestive functions. Hence, the transition to new dog food will be smooth. 


Spoiled food

Dogs are attracted to anything they see. Trash cans excite them. You can expect them to eat anything from the garbage can. This usually leads to an upset stomach. Dogs tend to eat visibly, spoiled food. This results in diarrhea, upset stomach, and other infections. Your dog could also develop pancreatitis. This is a serious condition, and you might have to hospitalize your pup. 

Diseases caused by bacteria and viruses

Raw meat or meat kept out for a long time develops bacteria. The bacteria found in such meat can cause diarrhea in dogs. It is dangerous because bacteria-induced diseases are transferable to other dogs as well. This leads to diarrhea once in two weeks. It can go on for years. Therefore, keep checking the stool to check if there is any blood in it or not.

Viral diseases such as coronavirus and rotavirus cause diarrhea in pups as well. It is followed by a series of vomiting, fever, cough, sluggishness, and lack of appetite. Therefore, take your pup to the vet immediately because you can contract it from your dog as well.

Tapeworm and other parasites

Tapeworms and other intestinal parasites are found in dogs. It is usually caused by drinking contaminated water or eating poop. Diarrhea induced by parasites is very distinct. It will have a different smell and color. Therefore, it is easier to detect. Take your pup to the vet immediately. Otherwise, it will hamper your pup’s health.

Poisonous items

Sometimes dogs wander off and end up exploring. It is wrong to stop them from exploring, but sometimes they harm themselves. Since dogs are attracted to anything, they might end up eating poisonous items. This includes a wide range of toxic plants and insects. Whenever your little pup eats something poisonous, he will have dangerous diarrhea. This could eventually lead to a visit to the emergency room. Hence, you know that the reason behind it is a poisonous item whenever you notice excessive diarrhea and vomiting.  


Giving the same diet to your pup can make him allergic to a different diet. Some dogs are naturally allergic to some food items. Whenever their bodies detect they are allergic to something, they remove it from the body. This usually results in diarrhea and vomiting. You can guess by checking what you gave to your pup, or you could notice other symptoms as well. Some of the symptoms of allergic reactions are:

  • Scratching
  • Chewing on paws
  • Licking the paws
  • Runny nose
  • Tiredness
  • Red skin
  • Itchy or scaly skin

Irritable bowel disease

Irritable bowel disease usually occurs due to inflammatory cells in the intestines of a dog. This causes severe diarrhea in dogs. There is no hidden cause behind it. It often happens out of the blue, and you are caught off guard. Therefore, immediately take your pup to the vet whenever you notice a little change in his poop.

Foreign objects

Your dog might end up eating anything he finds interesting. It could be a piece of plastic or paper. There are several foreign objects that your puppy could eat but couldn’t digest. These remain in the body of the pup forever and will cause several problems. These sometimes pile-up in the intestines, which lead to painful diarrhea in dogs.

Side effects

Sometimes diarrhea is just a side effect to several medications. Dogs are occasionally sensitive to medicines. Therefore, their bodies can react in different ways to different medicines. Dogs don’t know how to express their suffering. It usually shows in their body language. But if you look closely, you could notice different diseases in them as well. Therefore, diarrhea could be a way of their bodies, telling us that something doesn’t suit them.

Diseases affecting the kidney or liver

Kidney and liver diseases are also prevalent among dogs. It could be caused due to aging factors or because of trauma, health issues, intoxication, bacterial infections, viruses, congenital disorders, and much more. These usually lead to severe problems. But it can be diagnosed at an early stage. This is because of diarrhea that arises as soon as dogs develop such diseases. Thus, a thorough checkup is mandatory for dogs whenever you notice anything odd.


The points mentioned above clearly show that diarrhea could prove to be deadly if ignored. Dog diarrhea is painful and terrible. Dogs get weak and fragile due to diarrhea. It flushes energy and nutrition out of their bodies. This is already enough to make a dog suffer. But it is usually caused by underlying diseases. Therefore, take your pup to your vet whenever you notice potty accidents. Be vigilant and take a step before it is too late. A little hurry now could do wonders.
