Why Does My Dog Have Diarrhea At Night

Is It Diarrhea?

To study the dog poop, the veterinary physicians usually apply the rule of four C. Observing the ‘consistency,’ ‘colour,’ ‘content’ and ‘coating’ of the feces include the rule.

The consistency of your dog’s feces is measured on a scale of five. A hard cylindrical stool is of number five. The watery soft poop is number one.

The perfect color of the dog poop is chocolate brown. Other different colors indicate different issues. There should not be any coating like mucus, blood, etc. Content should be smooth like play-dough.

Don’t worry if still, your doggy’s poop cannot reach the goal! It is diarrhea, only when its consistency is overly soft liquid.

The Most Common Causes of Diarrhea In Dogs

Diarrhea in your puppy is alarming when it happens with no warning and can be hard to deal with. But if you know the causes of diarrhea in dogs, it makes them much easier to manage. Here are the common causes of diarrhea in dogs –

Anxiety or Stress

It can cause vomiting or loose stools. Anxiety causes malabsorption which later leads to diarrhea.

Viral Infections

In dogs, diarrhea can be caused by infectious agents such as Parvovirus, Distemper, or Coronavirus. Viral causes of diarrhea may last longer than bacterial causes.

Ingesting Toxins or Poisons

Poisonings can cause vomiting, diarrhea, or loss of appetite. If it is poison ingestion, toxins may require veterinary intervention and hospitalization.


This is a parasite that causes diarrhea in dogs.

Dietary Changes

If you feed your dog too much meat, it will sometimes cause diarrhea. If you are switching your dog’s diet to raw food, it can also cause diarrhea.

Eating Spoiled Food or Garbage

Dogs can safely eat items that are spoiled. But when they eat food that is past its expiry date or other items they cannot digest, it can cause diarrhea.

Vomiting and Other Diseases in Dogs

If you have a dog, it’s important to know the signs of disease that your pet may show. In most cases, vomiting is one of the most common diseases. There can be many diseases why your dog can vomit. These are-

  1. Pancreatitis – the pancreas produces enzymes that aid in digestion. If there is an infection, the enzymes may affect the stomach and cause a dog to vomit.
  2. Infection such as Parvo Virus – This can be transmitted from another infected dog and is also airborne. Dogs who contract this virus begin vomiting and generally have diarrhea as well.
  3. Foreign object – Your dog might have eaten something it shouldn’t have, like a bone, leather belt, or sock, and will begin to vomit soon after eating it.
  4. Motion sickness – This can happen to dogs that are on the move and have taken a very long road journey. When they get to their destination, the motion sickness will end.
  5. Megaesophagus – This can be caused by a stomach blockage or oral region infection. Your dog will begin to vomit soon after swallowing.
  6. Food poisoning – If your dog’s esophagus becomes excessively large, this can cause vomit.
  7. Liver disease – The liver is responsible for breaking down the toxins in your dog’s system. If it is functioning at a low level, then the toxins will remain in your dog’s body and cause them to vomit.
  8. Intestinal parasites – These are worms that can be passed on to a dog by another animal or human. They usually cause vomiting, diarrhea, and weight loss.

My Dog Has Diarrhea but Is Acting Fine

It is advisable to give dogs with very watery small intestinal diarrhea a bland food, such as boiling white flesh chicken or low-fat cottage cheese combined with white rice, mashed potatoes, or pasta, as long as they are still performing normally and would eat.

Your dog is probably not in pain if they have diarrhea but otherwise seems to be in good health. By whining or behaving differently than usual, dogs are quite effective at letting people know when they are in pain.

While there’s no immediate need for concern, you should watch your dog’s continued symptoms. You should call your veterinarian if they seem weak, tired, or more tired than usual.
