Lyka's essential guide to dog gut health

Your dog’s gut does a lot more than just digest food - it powers their immunity, mood and overall health. A healthy gut microbiome can lift energy levels, support better behaviour, and help prevent long-term issues.
From curious puppies to slower-moving seniors, every dog’s gut deserves support. Here’s how to keep it balanced - and why it matters.
Your dog’s gut microbiome: why it’s important to their whole health
Your dog’s gut is home to trillions of bacteria, fungi and other microbes - this is their gut microbiome. These tiny helpers break down food, absorb nutrients, and act as a frontline defence against harmful pathogens.

What impacts your dog’s microbiome
When the microbiome is balanced, your dog’s digestive system works efficiently. But when it’s disrupted (dysbiosis), you may notice symptoms like diarrhoea, constipation, bloating, gassiness, or even skin and behaviour issues.
Several factors can affect the balance of gut bacteria:
Diet: The microbiome is incredibly responsive to food. Rapid diet changes or low-quality, highly processed diets can reduce microbial diversity.
Antibiotics and medications: Some drugs can wipe out beneficial bacteria, allowing less helpful microbes to take over.
Stress: Anxiety or routine changes can influence digestion and microbial balance.
Illness and infections: Parasites, viruses, and inflammatory gut diseases can shift the microbiome.
Age: Puppies and senior dogs have different gut needs as their microbiome develops and changes over time.
How to keep your dog’s microbiome healthy, balanced, and robust
Keep your dog’s digestive system functioning smoothly by supporting their gut microbiome.
Real food ingredients - minimally processed meals rich in dietary fibre from fresh vegetables provide nourishment for good bacteria. Quality animal protein is highly digestible and supports your dog’s metabolic function.
Probiotics - “good bacteria” supplements that can help restore the balance like Lyka’s Go-To gut helper.
Microbiome Restorative Therapy (MBRT) - a vet-prescribed treatment that transfers healthy gut bacteria to unwell dogs. It’s not a standard treatment and would only be considered in certain cases.
Lyka meals are designed by Board-Certified Veterinary Nutritionists to provide optimal nutrition for your dog to support their health from inside out. Lyka meals include naturally occurring prebiotics from fibre-rich ingredients, like psyllium husk and various fruits and vegetables, which support a healthy gut microbiome.

The gut-brain axis
Did you know your dog’s gut and brain are constantly “talking” to each other? This communication happens through the gut-brain axis - a network of nerves and chemical signals linking their digestive system, immune system, and mental health.
When your dog’s gut is healthy, this communication helps regulate mood and stress. But when the gut is inflamed or imbalanced (a state called dysbiosis), it can contribute to anxiety-like behaviours or chronic conditions.
Nurturing and nourishing a diverse and balanced microbiome is key to a fully functioning gut-brain axis.

Common gut-related health issues
Gastrointestinal conditions are the second most common reason to visit the vet, according to Pet Sure’s Pet Health Monitor 2025 report. Many digestive upsets can be prevented or managed through nutrition.

Gut health for puppies
Puppies have developing digestive systems, and their microbiome is still being established. Gentle, consistent nutrition and slow transitions help reduce digestive stress.
Gut health for seniors
As dogs age, their digestion can slow and their nutritional needs change. Supporting fibre intake, hydration, and digestible protein can help maintain comfort and regularity.
