Is it Normal for a Dog to Have Diarrhea?

Yes, mild to moderate cases of diarrhea are common in dogs from time to time.

So, my dog has diarrhea but is acting fine – how is this possible? This could occur due to eating something that irritates your dog’s stomach (like new food or table scraps). On the other hand, dog diarrhea can also result from parasitic infections or viral infections in the intestinal tract, food allergies, or foreign objects in the small/large intestines.

It could also result from underlying health issues such as liver disease, pancreatitis, kidney disease, colitis, and so on. Anyway, diarrhea is a frequent incident for dogs and can be cured at home if the case is mild.

Why Does My Dog Have Diarrhea but Acts Normal?

If your dog has diarrhea, you will expect it to show some sign of discomfort. However, sometimes it may act completely normal. According to vets, there are a few reasons attributable to this behavior:

  • Causes of Diarrhea. The common cause of diarrhea has much to do with your dog’s reaction to it. If it is a frequent diarrhea attack that happens when your dog diverts from the regular food, and thus, may not be feeling extremely uncomfortable or showing any signs.
  • Spread of Diarrhea. Your dog may act completely fine if the cause of the diarrhea is localized to the gastrointestinal tract only. However, if the allergy or infection starts spreading to other organs, your dog can show symptoms of discomfort.
  • Chronic Diarrhea. If your dog has chronic diarrhea, not showing any symptoms is quite natural. Chronic diarrhea is a condition where your dog’s body is used to diarrhea attacks, and it has become a part of their body’s general reflex. In such cases, your dog may feel and act normal even during diarrhea.

Should I be Worried if My Dog Has Diarrhea but is Acting Fine?

The answer is – it depends on the bout of diarrhea.

If diarrhea has lasted more than three days and your dog is still not showing any discomfort, you should immediately seek medical help. Consult a veterinarian to find out the cause and spread of diarrhea in such cases before the situation escalates.

Can Dog Diarrhea be Contagious to Other Dogs?

Yes, if the causal organism of the diarrhea is a virus or bacteria, dog diarrhea can be contagious.

Diarrhea can spread to other dogs in such cases if they sniff or lick the infected feces or drink water from a shared bowl.

How Long Should Diarrhea Last in Dogs?

Diarrhea in dogs could last depending on their age, size, lifestyle, immune system, and more.

Based on this, bloody diarrhea can last from a few days to up to a few weeks. On average, diarrhea lasts 2-4 days; however, sometimes, it goes beyond four days.

Senior dogs are expected to have irregular bowel movements as their digestive capabilities tend to deteriorate with age.

Your dog can also have prolonged or frequent diarrhea attacks if they don’t have a fixed diet and tend to eat a lot of unhealthy treats and kibble.

How Long Should a Dog Have Diarrhea Before Going to the Vet?

If your furry friend is experiencing diarrhea for a few days (usually less than three), you can opt for home remedies as listed above.

In case the diarrhea is severe, bloody, or accompanied by excessive vomiting, call your vet as soon as possible. Also, seek veterinary care if the dog’s diarrhea lasts for more than three days.

In summary, diarrhea is common and benign in many dogs. However, sometimes it can indicate a more severe issue, such as inflammatory bowel disease, viral infections (parvovirus, coronavirus, or distemper), bacterial infections (like Salmonella), or parasites (roundworms, hookworms, Giardia). Long and untreated diarrhea has a negative impact on the dog’s health.
