If you visit any drug store, you will find several anti-diarrheal medicines for cats and dogs. Tylosin, Metronidazole, etc., are generally recommended for intestinal inflammation of dogs. Other than these, you can also use some dewormers on your adorable dog for dog diarrhea treatment.

Do you know that your dog's mouth is designed to tear, crush and swallow food? Like humans, dogs also have a salivary system. The canine saliva generally kills the bacteria in the food, which are responsible for making them sick. There are several direct dog diarrhea causes. Let's know about them in detail.

Dietary indiscretion

Dietary indiscretion is commonly known as garbage toxicosis. The vets often call this problem "garbage gut." Dogs tend to eat too much. This causes both obesity and canine digestive upset. Sometimes consumption of spoiled food also causes diarrhea in dogs.

Change in diet

An abrupt change in the diet can also be a reason behind this kind of canine digestive disorder. So, you should not switch your little friend from a vegan diet or non-veg diet to any other special diet instantly. The diet change should be a long process where your dog will get some time to acclimatize itself to the new food routine. Also, if you switch your dog to a new food brand, your dog can slightly suffer from digestive upset. So, you should talk to your vet before you feed your dog anything new.


If your canine friend has a weak immune system, it will suffer from frequent parasite attacks as well. Several worms like roundworms, hookworms or whipworms can cause diarrhea in dogs. Most puppies get diarrhea from these worms.


Some types of food allergies can also be one of the dog's diarrhea causes. These allergies get worse by the intake of some particular food ingredients. Other than dog diarrhea, these allergies can cause vomiting and other gastrointestinal issues as well. So, check the food components before you purchase it.

Toxic substance

The food habits of dogs and humans are pretty different. The dogs find onions, chocolate, avocado, alcohol, etc., as toxic substances. If by any chance, your dog consumes these items, you should bring them out from your dog's mouth. Otherwise, it can lead to dog diarrhea at any time. In the worst case, your dog can swallow plastic or synthetic fur, which can cause incessant vomiting and diarrhea. So, keep an eye on what your dog is eating.


Generally, viruses named Parvovirus, Distemper, Coronavirus, etc., show symptoms of canine diarrhea. But, this type of dog diarrhea goes away on its own.

Bacterial infections

Like humans, in dogs also, a specific bacteria named salmonella causes diarrhea. To get rid of these bacterial infections, you should give your dog some doctor-recommended antibiotics.

Drug interaction

Dogs often suffer from itchiness, ear infections, dry mouth, digestive disorders, etc. So, the vets provide them with some medications. These medications can interact with each other and cause stomach upset in dogs.

Emotional disturbance

If you are a first-time dog owner, you should know that dogs are pretty emotional creatures. They go through anxiety, depression, etc., just like humans. Due to stress also, they sometimes suffer from canine diarrhea.

It is a well-accepted fact that prevention is better than cure. Your dog should have a balanced diet, proper on-time vaccination, etc. Also, try to take the canine friend out for a brisk walk and exercise. This healthy regime can only keep your dog away from dog diarrhea.

When should I be concerned about my dog's diarrhea?
If your dog has just diarrhea, you might not have to worry about it. But, if the dog's diarrhea is paired with abdominal pain, blood with stool, fever, etc., it is time to take the dog's diarrhea seriously. For chronic soft stool, you also should visit a vet. There is no harm in taking the fruitful advice of an experienced vet.
What is the most common cause of diarrhea in dogs?
Diarrhea in dogs happens due to garbage eating mainly. In addition, dogs are likely to eat non-foods from the nook and corner of your house. Other than this, another common cause of dog diarrhea can be a change of diet. So, you can understand that dog diarrhea commonly occurs due to food-related issues.
How long does dog diarrhea last?
If it is mild diarrhea, it will probably go away within a day or two. But if your dog has symptoms of fever, weakness, and blood vomiting, it must be a serious kind of dog diarrhea. This type of diarrhea takes around a month to go away. The sick dogs should eat healthily and drink plenty of water in the meantime.

In a nutshell, a healthy lifestyle is an answer to everything. You should serve your dog a healthy meal bowl full of fruits, vegetables, meat, and grain. If your dog suffers from diarrhea pretty often, maybe it is time to change its daily sedentary lifestyle. Let us know in the comment section below if you have any doubt regarding diarrhea in dogs.
