Dog Diarrhea? Causes + 5 Vital Tips


Common Causes of Dog Diarrhea

Dog diarrhea can have many causes.

They range from mild dietary issues to serious medical conditions.

Each cause affects your dog’s digestion in different ways.

Knowing these triggers can help you manage their recovery.

1. Dietary Changes

A sudden change in your dog’s diet, even a new treat, can disrupt digestion.

Switching foods too quickly is a major culprit.

Dogs need time to adjust to new ingredients and nutrients.

Pro Tip: When switching food, gradually mix in small amounts of the new food with the old over a week.

Real-Life Example: A dog that eats the same food for years may get an upset stomach after a new brand or unfamiliar treat.

2. Food Intolerances or Allergies

Some dogs have upset stomachs from some ingredients, like grains or proteins.

Signs of food intolerance may include itchy skin, vomiting, and, of course, diarrhea.

If you suspect a food allergy, consult your vet for an elimination diet.

Some dogs become intolerant of common ingredients, like chicken, beef, or grains.

Recognizing these sensitivities can help you choose a suitable diet.

3. Infections and Parasites

Common causes of diarrhea in dogs are infections.

They can be bacterial, viral, or parasitic, like Giardia or E. coli.

Dogs can get these infections from contaminated water, other animals, or unsanitary conditions.

Quick Tip: Regular deworming and hygiene practices are crucial for reducing these risks.

Example: Dogs that visit parks or interact with other animals may be more prone to parasites. So, preventive care is essential.

4. Stress and Anxiety

Dogs are sensitive to changes in their environment.

Stress can trigger temporary digestive issues, including diarrhea.

Moving, introducing a new pet, or even a visit to the vet can unsettle their stomach.

Fun Fact: Dogs, like humans, have a “gut-brain connection.” Stress affects their digestive health.

Real-Life Example: A dog may get an upset stomach and diarrhea if boarded or moved. The stress of a new environment can cause this.

5. Underlying Medical Conditions

Chronic or recurring diarrhea can signal serious health issues.

They include inflammatory bowel disease (IBD), liver disease, and pancreatitis.

In such cases, a vet will often recommend tests to identify the root cause.

Signs to Note: If diarrhea is persistent or paired with vomiting and lethargy, it’s time to see your vet.

When Diarrhea Is Likely Mild

Not all cases of diarrhea need a vet’s intervention. Sometimes, diarrhea can be mild and related to a minor dietary change or slight stress.

If the diarrhea resolves within a day without other symptoms, it’s likely a minor issue.

But if it lasts longer or worsens, contact your vet.

Signs That Dog Diarrhea Needs Veterinary Attention

While mild diarrhea can often be managed at home, certain signs suggest it is time to consult a vet.

1. Persistent Diarrhea

If your dog’s diarrhea lasts more than 24 to 48 hours, a vet visit is recommended.

Extended diarrhea can lead to dehydration, making quick intervention essential.

2. Blood or Mucus in Stool

Finding blood or mucus can indicate an infection, inflammation, or other internal issues.

This sign usually means more serious intervention is needed.

3. Accompanying Fever or Lethargy

Diarrhea with fever, low energy, or odd behavior may indicate an infection.

These symptoms warrant prompt attention from a veterinarian.

4. Vomiting Alongside Diarrhea

Both vomiting and diarrhea can quickly cause severe dehydration. This is dangerous for dogs.

If both symptoms appear together, consult your vet immediately.

5. Abdominal Pain or Discomfort

Signs of abdominal pain, like whining or trembling, are concerning.

Your vet can perform an exam to check for any signs of obstruction or pain.

Observation Tip: Track your dog’s stool. Its frequency, color, and consistency help vets diagnose issues.

5 Vital Tips for Managing and Preventing Dog Diarrhea

If your dog has diarrhea, these five tips can help. They will soothe your dog’s stomach and support recovery.

Tip #1: Offer a Bland Diet

A bland diet, like boiled chicken and rice, is easy on the stomach. It provides nutrients without causing irritation.

This diet can help your dog’s digestion. Vets often recommend it for mild diarrhea.

How to Feed: Start with small portions.

Gradually increase the amount over a few days as symptoms improve.

Duration: Limit a bland diet to 2–3 days, then reintroduce regular food slowly.

Interesting Fact: Chicken and rice are easy to digest.

They provide proteins and carbohydrates that help with recovery.

Tip #2: Ensure Proper Hydration

Diarrhea can quickly lead to dehydration, especially if it is accompanied by vomiting.

Keeping your dog hydrated is essential, so provide constant access to fresh water.

Signs of Dehydration: Check for dry gums, sunken eyes, and reduced skin elasticity.

These are signs of dehydration.

Gum Test: Gently press your finger on your dog’s gums—if the color doesn’t return quickly, they may be dehydrated.

Skin Test: Pinch the skin between your dog’s shoulder blades.

If it doesn’t snap back right away, your dog may be dehydrated.

Extra Help: You can add an electrolyte solution made for pets to their water to help restore lost fluids.

Quick Tip: If your dog won’t drink, try ice cubes or diluted chicken broth.

Tip #3: Avoid Sudden Dietary Changes

Abrupt changes in food can shock your dog’s digestive system, often resulting in diarrhea.

To avoid digestive upset, make dietary changes gradually.

How to Transition: Mix small amounts of new food with the current food, increasing the new food over a week.

When to Transition: If your pet has digestive issues, try a sensitive-stomach formula. Then consult your vet.

Pro Tip: A gradual transition lets your dog’s stomach adjust. It reduces the risk of gastrointestinal problems.

Tip #4: Consider Probiotics for Gut Health

Probiotics restore healthy bacteria in your dog’s gut.

They promote regular digestion.

They are available as pet-specific supplements in powder, chew, or capsule form.

Types of Probiotics: Look for dog-specific products.

They match dogs’ gut health needs.

How to Use: Start with a small dose.

Check your dog’s response before making probiotics a regular part of their diet.

Fun Fact: Probiotics can help prevent diarrhea in dogs, especially during stress, like travel or boarding.

Tip #5: Regular Parasite Prevention

Parasites, especially in outdoor dogs, are a common cause of diarrhea.

Regular preventive care is essential to keep your dog parasite-free.

How Often: Speak to your vet about a suitable deworming schedule, usually done monthly.

Types of Parasite Preventives: Use vet-approved meds for common parasites.

These include Giardia, roundworms, and hookworms.

Quick Tip: Always clean up after your dog on walks.

It reduces parasite exposure in public spaces.

Foods to Avoid During Dog Diarrhea

Certain foods can worsen diarrhea or irritate your dog’s digestive system.

Knowing what to avoid helps protect your dog’s stomach during recovery.

1. Dairy Products

Many dogs are lactose intolerant.

Dairy can cause digestive issues and bloating.

2. High-Fat Foods

Avoid greasy foods. They can irritate the stomach and cause upset.

This is especially true for dogs with sensitive stomachs.

3. Raw Foods

Raw food diets can carry bacteria. They can worsen diarrhea in dogs with sensitive stomachs.

4. Spicy or Seasoned Foods

These are hard for dogs to digest and can further irritate the digestive system.

Reminder: Stick to a bland diet. Avoid scraps and treats until your dog fully recovers.

When to Reintroduce Regular Food and Treats

After diarrhea, gradually reintroduce regular food and treats. This prevents a relapse.

Reintroduction Guide:

  • Day 1-2: 75% bland diet, 25% regular food.
  • Day 3-4: 50% bland diet, 50% regular food.
  • Day 5-6: 25% bland diet, 75% regular food.
  • Day 7: 100% regular food.

Observe for Reactions: Watch for signs of an upset stomach, like loose stools or discomfort, during the transition.

Avoid Treats Initially: Avoid rich treats until your dog’s digestion is stable.

Pro Tip: For dogs with sensitive stomachs, try a limited-ingredient diet. It may reduce stomach issues.

Additional Tips for Preventing Future Digestive Issues

To prevent diarrhea, stick to a diet, practice good hygiene, and manage stress.

1. Consistent Feeding Schedule

Feed your dog at regular times. This helps their digestion and reduces upset.

2. Safe Treat Choices

Choose treats formulated for sensitive stomachs, and avoid frequently changing treat types.

3. Dog Digestive Journal

Keep a record of what your dog eats, any new treats or foods, and any digestive reactions.

This can help you identify food sensitivities over time and avoid triggers.

4. Stress Reduction

Dogs are sensitive to stress

To prevent stress-induced digestive issues, minimize environmental changes. 

Also, provide a calm, secure space.

5. Dog-Proofing Your Home

Keep human foods and small objects out of reach. Ingesting them can cause digestive issues in dogs. 

Keep hazardous items, like chocolate, small bones, and indigestible toys, away.

6. Routine Vet Checkups

Regular vet visits can find early signs of food sensitivities or health issues that may cause diarrhea.

Interesting Fact: Dogs fed, exercised, and rested on a routine are less likely to have stress-related digestive issues.
