In dog health, the gut doesn’t whisper - it speaks. Through every walk, bag, and glance at what’s left behind, your dog’s stool offers clues to internal balance or imbalance. Here’s how to decode it.
1. The Four Stool Types - and What They Signal

Hard, Dry Stools: These often suggest dehydration or insufficient dietary fibre. Fibre supports water retention in the colon and helps form soft, passable stools. A lack of it can lead to compact, dry waste that may be uncomfortable or even painful to pass.
Well-Formed, Moist Stools: This is the ideal. Firm but not hard, moist but not loose. These stools indicate optimal hydration, balanced fibre intake, and a stable gut microbiota. Think of this as your dog's digestive sweet spot.
Loose, Unformed Stools: Often a sign of dysbiosis or mild gastrointestinal upset. When the gut struggles to absorb water properly, stools become softer and less structured. This could result from stress, dietary changes, or minor imbalances in microbial populations.
Watery or Mucous-Laden Stools: A red flag. Persistent watery stools, especially those accompanied by mucus or blood, may point to infections, parasites, or inflammatory bowel conditions. These cases warrant veterinary attention.
Why Fibre Matters: More Than Just Bulk
Fibre plays several key roles in digestive health. Soluble fibres (like pectins and inulin) feed beneficial bacteria, producing short-chain fatty acids (SCFAs) that strengthen the gut barrier and reduce inflammation. Insoluble fibres, on the other hand, provide physical structure to stool and help regulate transit time.
One study found that adding potato fibre to dogs' diets shifted their gut microbiota toward more favourable populations like Faecalibacterium and Bifidobacterium, while reducing potential pathogens like Fusobacteria (Panasevich et al., 2015).
The Microbiome: Your Dog's Internal Ecosystem
Your dog’s gut microbiome—the trillions of bacteria and other microbes in their intestines—is essential to digestion, immunity, and even mood. A stable microbiome helps ferment fibre into beneficial SCFAs, maintains gut wall integrity, and competes against harmful pathogens.
Disruption of this microbial balance can lead to loose stools, nutrient malabsorption, or recurring digestive issues. That's where targeted biotics come in:
Prebiotics feed good bacteria.
Probiotics add beneficial strains.
Postbiotics deliver beneficial bacterial metabolites directly.
Hydration: The Overlooked Factor
Hydration doesn't just impact your dog's energy or kidney function; it's crucial for stool formation. Water is needed to move digested material smoothly through the intestines. Dehydration, especially in active or senior dogs, often manifests first in their stool. Always ensure access to clean water and monitor intake during hot weather or illness.
Functional Ingredients That Help
Some ingredients go beyond basic nutrition to actively support digestive health:
Potato Fibre: Supports stool consistency and beneficial bacterial populations.
Yucca schidigera: Reduces faecal odour and may help soothe inflamed intestines.
Lactobacillus helveticus: A heat-treated postbiotic strain that promotes gut barrier integrity and immune support.
When to Be Concerned
Even with a healthy diet and stable microbiome, occasional fluctuations in stool are normal. But if you notice any of the following, it's time to consult your vet:
Persistent diarrhea or constipation
Blood or mucus in stool
Sudden colour changes (black, red, or pale grey)
Straining or discomfort during defecation
The Importance of Regular Monitoring
Regularly checking your dog's stool can provide valuable insights into their health. It’s a simple yet effective way to stay attuned to their needs. Just like you might keep an eye on your own health through various signs, your dog’s stool can serve as a barometer for their well-being.
Conclusion: A Clearer Picture of Gut Health
Your dog’s stool is more than waste—it’s a reflection of internal balance. By paying attention to consistency and supporting the gut with smart nutrition, you can prevent issues before they start.
Our products are designed with this philosophy in mind: microbiome stability, functional fibre, and clean daily rituals. Because better digestion doesn’t start in the gut. It starts in the bowl.
By understanding the nuances of your dog’s stool, you can take proactive steps to ensure their health and happiness. After all, a happy dog is a healthy dog!
