ISSUE FOCUS FEED & ADDITIVE MAGAZINE December 2025 47 When dysbiosis occurs and harmful bacteria dominate, L. reuteri helps counteract the imbalance through: • Pathogen inhibition: Preventing growth of inflammation-promoting bacteria • Anti-inflammatory support: Promoting production of anti-inflammatory cytokines and metabolites • Barrier enhancement: Strengthening the intestinal lining function • Immune modulation: Restoring local immune tolerance and appropriate responses In practical applications, L. reuteri contributes to improved gut health, reduced digestive functional disorders, and prevention of dysbiosis-related complications. These can include systemic effects like allergies, dermatitis, or behavioural problems. Its role is considered crucial in nutritional strategies aimed at rebalancing gut flora and supporting overall wellbeing. CONCLUSION: A FOUNDATION FOR LONG-TERM HEALTH Intestinal wellbeing is fundamental to the overall health of dogs and cats. The microbiota influences not just digestion, but immune function, skin health, behaviour, and overall vitality. Evidence-based nutraceutical strategies that support gut health provide lasting benefits. Modern multi-strain probiotic formulations offer targeted support backed by scientific research. Innovations in strain selection, ease of administration, and formulation adaptability make these products valuable tools. For professionals in animal nutrition and pet owners alike, prioritizing gut health through strategic probiotic use represents a proactive approach to companion animal care. Products like Reuteral Pet demonstrate how scientific advancement translates into practical daily support for pet wellbeing.
