Types of Dog Diarrhea

Understanding the characteristics of your dog’s diarrhea can help determine the cause and appropriate treatment.

Acute vs. Chronic Diarrhea

Acute diarrhea comes on suddenly and typically resolves within 1-3 days. It’s often caused by dietary indiscretion (your dog eating something they shouldn’t have).

Chronic diarrhea persists for more than 2-3 weeks, either continuously or in recurring episodes. This type requires veterinary attention as it often indicates underlying health issues.

Characteristics to Note

Common Causes of Dog Diarrhea

Understanding why your dog has diarrhea is the first step toward finding an appropriate solution. Here are the most common causes:

Dietary Indiscretion

The most common cause of acute diarrhea is your dog eating something they shouldn’t have—whether it’s garbage, spoiled food, or a foreign object. Dogs are notorious for their indiscriminate eating habits, which can lead to digestive upset.

Food Allergies or Sensitivities

Dogs can develop allergies or sensitivities to certain ingredients in their food. Common culprits include beef, dairy, chicken, wheat, soy, and corn. These reactions can cause diarrhea, especially if your dog has been eating the same food for an extended period.

Infections

Bacterial, viral, or parasitic infections can all cause diarrhea in dogs:

Bacterial infections: Salmonella, E. coli, Clostridium
Viral infections: Parvovirus, coronavirus, distemper
Parasites: Giardia, coccidia, roundworms, hookworms, whipworms

Stress and Anxiety

Just like humans can get “nervous stomach,” dogs can develop diarrhea when stressed or anxious. Common triggers include:

Changes in routine or environment
Travel
Boarding
New pets or family members
Loud noises (thunderstorms, fireworks)

Medications and Side Effects

Some medications, particularly antibiotics, can disrupt the balance of gut bacteria and cause diarrhea. Always discuss potential side effects with your veterinarian when starting new medications.

Underlying Health Conditions

Chronic or recurring diarrhea may indicate underlying health issues such as:

Inflammatory bowel disease
Exocrine pancreatic insufficiency
Liver disease
Kidney disease
Cancer
Addison’s disease

Toxin Ingestion

Exposure to toxic substances can cause severe diarrhea. Common toxins include:

Certain plants
Human medications
Chocolate
Xylitol (found in sugar-free products)
Household chemicals

When to Be Concerned About Your Dog’s Diarrhea

While occasional mild diarrhea might resolve on its own, certain situations require prompt veterinary attention:

Home Remedies and First Aid for Dog Diarrhea

If your dog’s condition doesn’t warrant emergency care, there are several steps you can take at home to help them recover:

Fasting Protocol

For adult dogs with simple acute diarrhea:

Withhold food (not water) for 12-24 hours
Offer small amounts of water frequently to prevent dehydration
If diarrhea improves, gradually reintroduce bland food

Note: Do not fast puppies, senior dogs, or dogs with known medical conditions without veterinary guidance.

Hydration Strategies

Preventing dehydration is crucial when your dog has diarrhea:

Bland Diet Recommendations

After the fasting period, introduce a bland diet to soothe the digestive system:

Classic Chicken and Rice Recipe:

2 cups white rice (well-cooked)
1 cup boiled, skinless chicken breast (shredded)
Optional: 1 tablespoon plain canned pumpkin (not pie filling)

Feed small portions (¼ cup per 20 pounds of body weight) every 3-4 hours. Gradually increase portion size and decrease frequency over 2-3 days if stools improve.

The “Bacon and Grass Trick” for Gut Health

Many veterinarians and holistic pet experts have recently been discussing a simple yet effective approach to strengthening your dog’s digestive system and preventing chronic diarrhea episodes. This method combines:

A specific type of prebiotic fiber (the “grass” component)
A particular probiotic strain that dogs find irresistible (the “bacon” element)

This combination helps restore balance to your dog’s gut microbiome, which research shows is essential for proper digestion and immune function.

The approach has helped thousands of dogs overcome chronic digestive issues, including recurring diarrhea.

Ensure puppies are dewormed according to your veterinarian’s schedule and keep them away from areas frequented by unknown dogs until fully vaccinated.

Senior Dogs

Older dogs may experience diarrhea due to:

Medication side effects
Developing organ dysfunction
Reduced immune function

Senior dogs often benefit from easily digestible diets and may need more frequent veterinary check-ups.

Dogs with Chronic Conditions

Dogs with ongoing health issues like inflammatory bowel disease, exocrine pancreatic insufficiency, or food allergies may require:

Specialized diets
Long-term medication
Regular monitoring
Consistent feeding schedules
Stress management
