Companion Animal Microbiome and Welfare

The gut microbiome plays a significant role in companion animal health and behavior, with welfare implications for diet and antibiotic use.

Key Facts

The gut microbiome influences immune function, mental health and behavior in dogs and cats
Antibiotic use disrupts the microbiome and can cause lasting welfare effects
Diet quality significantly affects microbiome composition and overall health
Stress itself disrupts the gut microbiome creating a stress-gut-brain cycle

Welfare Considerations

Companion animal welfare is increasingly understood through the lens of the microbiome. Chronic stress disrupts gut bacteria, which in turn affect mood and behavior — creating a cycle that worsens chronic welfare problems. Over-use of antibiotics for minor infections causes lasting microbiome disruption that can affect long-term health. Understanding the gut-brain connection supports holistic approaches to companion animal welfare that address stress and diet alongside medical treatment.

What You Can Do

Work with a veterinary nutritionist to optimize your pets diet for microbiome health
Use antibiotics only when clearly indicated by a veterinarian
Manage stress in companion animals proactively
Consider probiotic support after necessary antibiotic courses
