Gut-skin axis in dogs Alternative treatments for canine skin infections Antimicrobial resistance

Researchers from Adelaide University conducted a detailed study on 12 golden retrievers over 90 days, finding that daily probiotic and postbiotic supplementation significantly improved gut and skin health. The findings suggest a strong link between gut health and skin quality in dogs, offering a potential alternative to antibiotics for managing skin infections. The authors caution that further trials are necessary to determine how these results translate to dogs with diagnosed skin diseases.
