Emerging research shows that the gut microbiome of domestic dogs plays a critical role in their physical health, immune function, and even behavioral wellbeing.
A healthy microbiome contributes directly to dog welfare through improved gut health, reduced inflammation, and potentially better emotional regulation. The gut-brain axis - communication between gut microbes and the brain - is now recognized as relevant to canine anxiety and stress responses. This means that nutritional decisions made by owners have welfare implications beyond simple body condition. High-quality, diverse diets, judicious use of antibiotics, and appropriate probiotic support can all contribute to a dog's overall wellbeing through microbiome health.
