What To Do If Your Dog Has Diarrhea (And How to Prevent It Before It Starts)

First: Don’t Panic - But Do Pay Attention

Dog diarrhea is extremely common and often linked to mild issues like diet changes or scavenging. However, it can also signal more serious problems such as infections or underlying conditions.

Diarrhea simply means loose or watery stools, often occurring more frequently than normal.

Common Causes of Dog Diarrhea

Understanding the cause helps you act quickly and correctly:

  • Sudden diet changes (switching food too quickly)

  • Eating something inappropriate (bin raiding, spoiled food)

  • Food intolerances or allergies

  • Parasites (e.g., worms, giardia)

  • Infections (viral or bacterial)

  • Stress or anxiety (travel, separation, new environments)

  • Chronic conditions like Inflammatory Bowel Disease

What To Do Immediately

1. Pause Food (Short-Term Fasting)

  • Withhold food for 12–24 hours (adult dogs only)

  • Always provide fresh water

Do NOT fast puppies, elderly dogs, or dogs with medical conditions without vet advice.

2. Keep Your Dog Hydrated

Diarrhea can quickly lead to dehydration.

  • Offer small, frequent sips of water

  • Consider dog-safe electrolyte solutions (vet-approved)

3. Introduce a Bland Diet

Once symptoms settle:

  • Boiled chicken (no skin, no seasoning)

  • White rice

  • Plain scrambled egg

Feed small portions and gradually reintroduce normal food over 2–3 days.

4. Consider Probiotics

Dog-specific probiotics can help restore gut balance and speed recovery.

5. Monitor Closely

Keep an eye on:

  • Stool consistency

  • Frequency

  • Energy levels

  • Appetite

When To Call the Vet

Seek veterinary help immediately if you notice:

  • Blood in stool

  • Black/tarry stools

  • Vomiting alongside diarrhea

  • Lethargy or weakness

  • Signs of dehydration (dry gums, sunken eyes)

  • Symptoms lasting more than 48 hours

Serious conditions like Parvovirus can start with diarrhea and require urgent care—especially in puppies.

How To Prevent Dog Diarrhea

Prevention is obviously better and these tips can help:

1. Stick to a Consistent Diet

  • Avoid sudden food changes

  • Transition any diet changes gradually over 7–10 days

2. Control What Your Dog Eats

  • Keep bins secure

  • Avoid feeding table scraps

  • Be cautious on walks (as many owners know - dogs love “mystery snacks”)

3. Regular Parasite Control

Routine worming helps prevent digestive upset caused by parasites.

4. Maintain Good Hygiene

  • Clean food and water bowls regularly

  • Pick up waste promptly in the garden

  • Wash your hands regularly

  • Ensure your dog’s bedding is clean and wash their toys on a regular basis (can be a breeding ground for bacteria, parasites and fungi that can give your dog an upset tummy and worse)

5. Reduce Stress

Dogs can develop diarrhea due to anxiety.

  • Maintain routine

  • Provide enrichment and exercise

  • Gradually introduce new environments

  • Provide them as calm an environment as you can to help your dog’s emotional wellbeing.

Know Your Dog’s “Normal”

Every dog is different. Knowing what’s typical for your dog’s stool, appetite, and behavior makes it easier to spot problems early.
