The Gut-Immune Axis
Why This Matters
If your dog seems to catch every bug going around or battles recurring infections, the answer may lie not in boosting immunity, but in supporting the gut. Approximately 70% of immune tissue resides in the gut, making it ground zero for disease resistance.
What the Science Shows
- The gut-associated lymphoid tissue (GALT) is the body’s largest immune organ
- Gut bacteria ‘educate’ the immune system, teaching it to distinguish between threats and harmless substances
- When this education fails due to dysbiosis, the immune system may overreact (allergies) or underreact (infections)
- SCFAs (short-chain fatty acids) promote regulatory T cells that prevent excessive inflammation whilst maintaining pathogen vigilance
How to Support It
- Feed prebiotic fibres to support SCFA-producing bacteria
- Maintain gut barrier integrity with L-glutamine and zinc
- Include omega-3 fatty acids for balanced inflammatory responses
- Consider postbiotics for dogs with impaired bacterial populations
Key Insight
A healthy immune system isn’t about maximum strength — it’s about appropriate responses. The gut trains the immune system to react proportionally.
