Diarrhea is defined as stools that are softer, looser or more watery than usual. They can be larger or smaller in volume than your dog's regular stool. Diarrhea is a sign of illness or infection, not a diagnosis.

In addition to changes in stool consistency, diarrhea may be associated with various physical and behavioral changes. A few of the more common signs include:

• Exhibiting increased urgency to defecate

• Pacing or inability to settle

• Having accidents in the house

• Squatting or straining to defecate with no production

• Appearing lethargic

• Vomiting

• Losing appetite

• Running a fever

• Presenting signs of dehydration, such as sunken eyes or dry gums

• Losing weight (in the case of chronic diarrhea)

If you've found yourself wondering whether you should head to the vet for your dog's diarrhea or wait it out at home, you aren't alone. It's always best to err on the side of caution. However, contact your vet right away if your dog:

• Has stopped eating and/or drinking.

• Is lethargic.

• Is producing black, tar-like or bright red diarrhea.

• Is vomiting.

• Has diarrhea for 48 hours (or if their condition has steadily worsened in this time frame).

Acute cases of diarrhea that don't worsen and aren't accompanied by other clinical signs are often self-limiting, meaning they may resolve at home without the need for specific therapy or veterinary intervention. However, always check in with your vet for advice.

There are many treatments available for diarrhea in dogs depending upon the cause. For example, parasites in dogs and canine pancreatitis would have different treatments, as one requires a dewormer and the other requires nutrition management, fluid therapy or other supportive care.

But before you become overwhelmed by potential outcomes, remember that most cases of diarrhea resolve with minimal treatment. In some cases, your vet may recommend withholding food for 12 to 24 hours to allow time for inflamed bowels to calm down and prevent further irritation and water loss from the GI tract. When reintroducing food, they may instruct you to feed your dog a bland, low-fat, easily digestible food.

Fiber for Dogs With Diarrhea

While fiber can help normalize minor to moderately abnormal stools, giving dogs fiber for diarrhea is case-dependent. For constipation, fiber can provide bulk and help move contents along; for diarrhea, fiber can help with water absorption. Because it can affect digestive function in different ways, ask your vet if they think your dog is a good candidate for fiber.

Fluids and Medications

Diarrhea can lead to dehydration. Dehydration in dogs is a serious condition requiring veterinary care, so offer plenty of fresh water during an episode of diarrhea to help replace lost fluids. If needed, your vet may recommend supportive care, addressing hydration and/or electrolyte concerns with IV fluids.

Your vet may suggest over-the-counter medications to halt diarrhea. However, never administer medications to your pet without your vet's guidance. They may also prescribe medication, though most treatment plans will include multiple modalities, with nutrition always being one focus.

Diarrhea is common in dogs, and most cases require minimal intervention. Seek veterinary care when your dog's diarrhea persists for 48 hours or is associated with other signs of illness. Your vet will develop a treatment plan dependent upon the specific cause and severity of signs. Dogs with frequent or chronic digestive issues may need long-term nutritional management.

Your dog's food can have a significant impact on their GI health. Work with your vet to determine the best nutritional approach for your dog's needs. With the proper care and attention, you can help your pup feel better in no time.
