Research into the gut microbiome of dogs and cats is revealing connections between intestinal bacteria, immune function, behaviour, and disease. These insights are opening new approaches to companion animal health and welfare.
Microbiome research is expanding our understanding of companion animal health in ways that have direct welfare implications. Chronic gastrointestinal disease is a significant source of suffering in dogs and cats, and microbiome-targeted interventions may reduce this suffering more effectively than current approaches. The connection between gut microbiome and anxiety and behavioural disorders also opens new welfare-relevant treatment pathways. However, the commercial pet probiotic market currently runs well ahead of the evidence — owners seeking microbiome-based health improvements should seek veterinary guidance based on validated products.
