Research into the gut microbiome of dogs and cats is revealing connections between microbiome composition, diet, behavior, and welfare. Understanding the microbiome opens new avenues for welfare improvement.
Microbiome science is revealing that gut health and welfare are more closely connected than previously understood. Dogs and cats with dysbiosis - disrupted microbiome composition - show increased anxiety, poorer immune function, and gastrointestinal problems that reduce quality of life. Chronic stress itself disrupts the microbiome, creating a bidirectional relationship between welfare and gut health. Antibiotic stewardship in companion animal medicine matters for microbiome welfare as well as resistance concerns. Dietary approaches to microbiome health are accessible to all pet owners.
