Is your dog suffering from chronic or acute Diarrhea?

Acute diarrhea has less severity compared to chronic diarrhea. Usually, when your dog has chronic diarrhea but acts fine, it’s because he has gotten so used to the disease that he doesn’t behave any differently.

Acute and chronic diarrhea have distinct symptoms and severity. Let’s see how they differ.

The difference between Acute and Chronic Diarrhea

Acute diarrhea happens without any warning. The reason for it is something that directly disturbs the doggy’s gut. Acute diarrhea is common and can clear up in a day or two on its own.

20 Common causes of Diarrhea in dogs

There are various reasons for diarrhea in dogs—both acute and chronic. Let’s overview them briefly.

Acute diarrhea causes

1. Overeating

Overeating puts an excessive workload on the dog’s digestive system, causing stomach pain and diarrhea.

Not only that, overeating can cause over nutrition. This means weight gain as well as tummy swelling, abdominal pain or discomfort, and even loose stools or diarrhea. If you overfeed your dogs, their digestive system is on overload. The dog’s digestive system stops being efficient and instead is causing indigestion.

2. Contaminated food

Frequently consuming moldy or rotten food can give the dog a bad case of the runs. Always serve your dog fresh food.

Our open and exposed garbage can is like a buffet for our dogs. The food could be rotten or spoiled and our furry family members will still attempt to eat it. These spoiled food contain bacteria that can cause upset stomachs in dogs and lead to diarrhea. Diarrhea is a way for the dog’s body to get rid of poisonous or rotten food.

3. Food allergies

Food that is otherwise safe to eat can also cause your dog digestive distress. It happens when your dog is allergic to that food. If your pooch is lactose intolerant, avoid feeding them dairy products.

Our canine family members can also be allergic to wheat products, grain products, or even soy products. 

4. Poisoning

Common human foods like chocolate, onion, garlic, raisins, and grapes can poison and cause diarrhea in dogs.

If you know certain food are poisonous to dogs, keep them on high surfaces or counters and make sure your dogs can’t reach them. 

This also includes plants around the house that are poisonous to dogs such as the Hostas plant. Be sure to keep such plants in areas where your dog can’t jump up and sneak a bite or be near them.

5. Human food

Frequently feeding your dog human foods high in fats, salt, and sugar can cause diarrhea.

Avoid feeding your dogs processed food as well. Processed food contains preservatives and additives to keep the food fresh and have a longer shelf life. Unfortunately, it is unhealthy for dogs, and eating highly processed food can cause diarrhea in dogs. 

Opt to make dog-friendly meals or treats yourself at home instead.

6. Dietary change

A sudden change in your furry friend’s diet can shock his digestive system, making it work incorrectly.

7. Medicine side effects

Some medicines and drugs come with side effects which include diarrhea.


A viral infection like Parvo, canine coronavirus, or distemper can attack your furry friend’s digestive system and this can lead to diarrhea.

9. Bacteria

When the bad bacteria in the doggy gut outnumber the good bacteria, it leads to gastrointestinal distress as well as diarrhea. 

Handy Hint: You’ll want to get probiotics for dogs if the bad bacteria in their gut is greater than the good bacteria. Yakult is packed full of probiotics and good bacteria. Check out Can Dogs Drink Yakult? to find out if this sweet drink is safe for dogs.

10. Intestinal blockage

Food wrappers, candy wrappers, large pits, bones, toys, socks, and other indigestible items can cause intestinal obstruction in dogs, leading to painful diarrhea.

11. Internal injury

A sharp object such as a bone shard, fishbone, or wood can damage the intestines and lead to bloody diarrhea.

18. Injury

An accident, severe injury, or trauma to the dog’s gastrointestinal tract can cause bloody or dark diarrhea.

19. Liver disease

Liver diseases like ulcers, inflammation, cancer, and complete liver failure are often accompanied by diarrhea.

At-home remedies if your dog has Diarrhea

You can treat doggy diarrhea yourself if your canine friend is in good health and has no underlying medical issues. After consulting with a vet, here are ten things dog owners can do at home.

1. Fasting

Dogs suffering from gastrointestinal distress will benefit after their digestive system gets a 12 to 24-hour rest via fasting.

2. Infrequent meals

After the initial fast, reduce the feeding frequency and increase the time between each meal to give your four-legged friend’s stomach some time to rest.

3. Bland food

Put your dog on a plain diet of boiled white rice and boneless chicken. Add his usual dog food little by little as his condition improves.

4. Food with starch

Starchy foods like Butternut Squash, sweet potato, boiled potato, and white rice help make the poop more firm.

5. Fibrous diet

Fibrous foods like pumpkins and special fiber supplements can help recover normal gastrointestinal function in dogs.

6. Probiotics

Probiotics are healthy bacteria that keep the dog’s gut health in check. Fermented foods like kefir, yogurt, and cottage cheese carry these beneficial gut bacteria naturally.

7. Prebiotics

Prebiotics supports the growth of good bacteria in the doggy gut. While there are numerous natural sources of prebiotics, you can also get them in specially designed dog food.

8. Hydration

Keeping your dog’s water level up is crucial during diarrhea. You can also add an electrolytic solution to the water to help recover the lost electrolytes.

9. Anti-diarrheal medicines

Some human anti-diarrhea medicines can work on dogs too. Flagyl and Tylan are two over-the-counter medications you can use on dogs with your vet’s approval. Be sure to consult with your vet first.

10. Dewormers

If your dog has intestinal parasites, your vet may prescribe dewormers for you to administer at home. Once the parasites are gone, your dog will recover its gastrointestinal function.

Here is a deworming treatment for canines that’s highly recommended by our vets. 

When to see the veterinarian?

Prolonged and excessive diarrhea that lasts for more than two days is a cause for concern and requires medical treatment. You should also check with the vet if your dog’s behavior changes and starts showing other symptoms. Lastly, any odd coloration, worms, or blood in the poop is a red flag.

When can dog Diarrhea lead to emergency care?

When doggy diarrhea has caused severe dehydration, and your dog cannot drink water, they may require emergency care. Another cause for an emergency would be diarrhea caused by acute organ failure or any other severe medical condition.

Dog Diarrhea Do’s

1. Inform the vet

Whether it seems mild or severe, the first thing to do is to inform your dog’s vet. Any home treatment must have their approval first.

2. Fast

A 12 to 24 hour fast can rest your dog’s digestive system and aid recovery.

3. Isolate

Parasites and infections can transmit to other dogs. Make sure to isolate the affected dog to contain the spread.

4. Check for dehydration

Dehydration is a lingering threat when your dog is suffering from diarrhea. Give your furry friend plenty of water and electrolytes.

Dog Diarrhea Don’ts

1. Hold water

When fasting your dog, continue giving him water. Your dog will lose plenty of fluids with his runny stools and dehydration will make things worse.

2. Administer medicines yourself

Don’t administer medicine—even the over-the-counter ones—without your vet’s approval. Ask your vet first before administering any medicine to your pooch.

3. Feed the same diet

If your dog has diarrhea, you should switch to a plain boiled, unseasoned white rice and chicken diet.

4. Wait too long

After your dog comes down with diarrhea, you shouldn’t wait any longer than three days before taking him or her to the vet.

5. Leave the dog unsupervised

An unsupervised dog would be free to eat unhealthy food, which would worsen his condition.

6. Ignore severe symptoms

Be on the lookout for other symptoms, as they can tell a lot about the reason for your dog’s diarrhea.
