The least romantic moment of the relationship
You find the "surprise" on the floor. Clean up. Three hours later: another "surprise." And again. Your dog has diarrhea.
It is one of the most common issues that every dog owner faces. In 70% of cases, it resolves on its own with the right home protocol. In the other 30%, a trip to the veterinarian is necessary.
Here’s how to distinguish and manage it.
What is diarrhea
Diarrhea: an increase in the frequency, volume, or liquidity of feces.
Characteristics:
- Soft or liquid stools.
- Increased frequency (more than 2-3 times a day).
- Sometimes with mucus.
- Sometimes with blood.
Types:
1. Acute diarrhea (duration <14 days):
- More common.
- Common causes: dietary, viral, parasitic.
2. Chronic diarrhea (duration >14 days):
- More serious.
- Causes: inflammatory diseases, allergies, tumors.
The most common causes (acute diarrhea)
1. Dietary indiscretion
The most common: dog eats something "inappropriate."
Examples:
- Table scraps.
- Garbage.
- New foods introduced suddenly.
- Too many snacks.
- Excessive raw vegetables.
Characteristics:
- Sudden diarrhea.
- No other significant symptoms.
- Normal dog behavior.
Resolution: bland diet, usually 24-48 hours.
2. Sudden change of food
Sudden change of kibble/diet = intestinal stress.
Solution: gradual changes (1 week of transition).
3. Intestinal parasites
- Worms (roundworms, hookworms).
- Protozoa (Giardia, Coccidia).
Characteristics:
- More frequent in puppies.
- Sometimes visible worms in the stool.
- Swollen abdomen.
Solution: deworming + veterinary visit.
4. Emotional stress
Moving, holidays, guests = stress = diarrhea.
Characteristics:
- Coincides with stressful event.
- No other symptoms.
Solution: remove stress + bland diet.
5. Viral/bacterial infections
- Parvovirus (unvaccinated puppies): deadly.
- Salmonella, E. coli, Campylobacter: often from raw food.
- Canine distemper: unvaccinated puppies.
Characteristics:
- Severe symptoms.
- Frequent vomiting.
- Lethargy.
- Sometimes fever.
Solution: veterinarian immediately.
6. Acute pancreatitis
Causes: the dog has eaten excessive fats (holiday leftovers, for example).
Characteristics:
- Abdominal pain.
- Severe vomiting.
- "Prayer" position (head down, rear up).
Solution: urgent veterinarian visit.
7. Poisoning
The dog has eaten something toxic:
- Chocolate.
- Onion, garlic.
- Raisins.
- Rat poison.
- Antifreeze.
- Mushrooms.
Characteristics:
- Acute symptoms.
- Vomiting.
- Sometimes seizures.
Solution: veterinary emergency.
The "24-hour" protocol for simple diarrhea
Step 1: partial fasting (12 hours)
Important: NO total fasting for many hours.
- Remove food for 8-12 hours.
- Water always available.
- Rest.
Step 2: bland diet (24-48 hours)
Classic recipe:
- 70% boiled white rice.
- 30% boiled skinless chicken or lean turkey.
- Cooked without salt, without seasonings.
Amounts:
- Small dog (under 10 kg): 100-150 g total, divided into 3-4 meals.
- Medium dog (10-25 kg): 200-300 g total, 3-4 meals.
- Large dog (over 25 kg): 400-500 g total, 3-4 meals.
Frequency: small meals every 4-5 hours.
Step 3: hydration
Crucial:
- Water always available.
- Maybe chicken broth (without salt).
- Pedialyte or electrolyte solutions for dogs in cases of severe diarrhea.
Dehydration: a greater risk of diarrhea. Recognize it:
- The skin of the scruff returns slowly when pulled (normally immediate).
- Dry gums.
- Sunken eyes.
- Lethargy.
Step 4: useful supplements
Probiotics for dogs:
- Restore intestinal flora.
- Brands: Fortiflora (Purina), Florentero, Diaroal.
- Cost: €10-20.
Clay (Smecta or specific veterinary types):
- Absorbs toxins.
- To be administered away from medications/food.
Step 5: gradual return to normality
After 48 hours of bland diet and normal stools:
Day 3: 50% bland diet + 50% regular food.
Day 4: 25% bland diet + 75% regular food.
Day 5: 100% regular food.
Never make a sudden change.
When to rush to the veterinarian
Go immediately if:
- ❌ Puppy under 6 months with diarrhea (rapid risk of dehydration).
- ❌ Older dog or with pre-existing conditions.
- ❌ Repeated vomiting associated (rapid fluid loss).
- ❌ Blood in the stool (bright red or dark/tarry).
- ❌ Severe lethargy.
- ❌ Abdominal pain (tense belly).
- ❌ Diarrhea lasting more than 48 hours despite bland diet.
- ❌ Visible dehydration.
- ❌ Fever (>39.5°C).
Common mistakes
Mistake 1: giving human anti-diarrheals without a prescription.
Some (Imodium) can be dangerous.
Mistake 2: forcing feeding.
Partial fasting is useful, not harmful (if for a short time).
Mistake 3: fatty food "to comfort."
Worsens diarrhea.
Mistake 4: sweetened milk/yogurt.
Lactose worsens diarrhea.
Mistake 5: waiting too long.
24 hours are okay for a healthy adult dog. More = risk.
The long-term diet post-diarrhea
After the acute episode:
1 week:
- Specific gastrointestinal kibbles (Hill's i/d, Royal Canin Gastrointestinal).
- Daily probiotics.
Afterwards:
- Gradual return to regular diet.
- Check that it was not the cause.
Prevention
To reduce future episodes:
- Consistent food:
Change gradually when you must.
No varied snacks.
No table scraps. - Regular deworming:
Deworming every 3-6 months. - Updated vaccinations:
Especially for parvovirus. - Limit "garbage" during walks:
Dog eating everything = at risk. - Regular probiotics:
Especially in sensitive dogs.
Daily or periodically.
Dogs at chronic risk
Dogs with gastrointestinal sensitivities (IBD, IBS):
- Specific hypoallergenic foods.
- Diet based on "rare" proteins (rabbit, duck, venison).
- Daily probiotics.
- Regular veterinary visits.
The truth
Diarrhea in dogs is common but manageable.
70% of cases: home protocol resolves in 24-48 hours.
30% of cases: veterinary care is needed.
Understanding the difference is key:
- Active dog, no other serious symptoms = monitor with a bland diet.
- Lethargic dog, vomiting, blood, pain = veterinarian immediately.
And always: hydration. Diarrhea kills not because of diarrhea itself, but because of dehydration.
Keep your dog hydrated, apply the protocol, and in most cases, everything returns to normal in 2 days. In the other cases: rush to the veterinarian without a second thought.
