Diarrhoea in dogs and puppies can be a stressful and messy experience for pet owners. When your furry companion is unwell, it's natural to worry about what’s causing the issue and how to help. Many cases of diarrhoea stem from infectious causes, which can range from mild to serious. Understanding these causes and knowing how to respond can make all the difference for your dog’s health and your peace of mind.
⚠️ What to Watch For
Diarrhoea in dogs can vary in appearance and severity. Identifying the signs of a potential infectious cause is the first step in addressing the problem. Symptoms to watch for include:
- Frequent loose or watery stools
- Vomiting alongside diarrhoea
- Fever or lethargy
- Dehydration (dry gums, sunken eyes, or reduced skin elasticity)
- Blood or mucus in the stool
While occasional diarrhoea might not be alarming, persistent or severe symptoms should be taken seriously, especially in puppies who are more vulnerable to dehydration and illness.
🔍 Possible Causes
Several infectious agents can cause diarrhoea in dogs and puppies. Here are the most common culprits:
1. Parvovirus
Canine parvovirus is a highly contagious and potentially life-threatening virus, especially in puppies. It targets the gastrointestinal tract, causing severe vomiting and diarrhoea, often with a distinct foul smell. Parvovirus spreads through contact with infected feces and contaminated surfaces.
2. Giardia
Giardia is a microscopic parasite that affects the intestines. Dogs can contract it by drinking contaminated water or ingesting infected feces. Giardia can cause intermittent or chronic diarrhoea, which may appear greasy or frothy.
3. Coccidia
Coccidia are another type of parasite that can cause diarrhoea, particularly in puppies. Infected dogs may experience watery or bloody stools. Puppies in crowded or unsanitary environments, like shelters or pet stores, are at higher risk.
4. Bacterial Infections
Bacteria such as Salmonella, E. coli, and Campylobacter can cause diarrhoea in dogs. These infections may result from eating raw or undercooked food, spoiled food, or exposure to contaminated water or feces.
5. Viral Infections
In addition to parvovirus, other viruses like canine coronavirus and distemper virus can lead to diarrhoea. While coronavirus is typically milder, distemper can cause severe gastrointestinal and respiratory symptoms.
6. Intestinal Worms
Roundworms, hookworms, and whipworms are common intestinal parasites that can lead to diarrhoea in dogs, especially puppies. Worm infestations often cause additional symptoms like a pot-bellied appearance, weight loss, or visible worms in the stool.
7. Fungal Infections
Though less common, certain fungal infections like histoplasmosis can cause diarrhoea in dogs. These infections are typically contracted by inhaling or ingesting fungal spores found in soil or bird droppings.
✅ What You Can Do at Home
If your dog has mild diarrhoea without other concerning symptoms, there are steps you can take to help them recover at home:
- Withhold food for 12–24 hours to allow the digestive system to rest (only for adult dogs, not puppies).
- Provide plenty of fresh water to prevent dehydration.
- Offer a bland diet, such as boiled chicken and white rice, for a few days before gradually reintroducing their regular food.
- Use a probiotic supplement designed for dogs to support gut health.
Monitor your dog closely during this time. If symptoms persist or worsen, seek veterinary care.
💡 When to Call a Vet
Some cases of diarrhoea require immediate veterinary attention. Contact your vet if your dog:
- Shows signs of dehydration
- Has blood or mucus in their stool
- Is vomiting persistently
- Is lethargic or unwilling to eat
- Is a young puppy with diarrhoea
Early intervention can prevent complications and ensure your dog gets the care they need. A vet may recommend diagnostic tests like fecal analysis, bloodwork, or imaging to determine the cause of the diarrhoea and develop a treatment plan.
