Companion Animal Microbiome and Welfare

The gut microbiome plays a significant role in companion animal health and behaviour. Understanding microbiome welfare helps owners make better nutritional decisions.

Key Facts

Companion animal gut microbiome diversity correlates with immune function and behavioural health
Antibiotic treatment significantly disrupts the microbiome for weeks to months
Diet is the primary modifiable factor influencing microbiome composition in dogs and cats
Probiotic research in companion animals is growing but evidence for specific products is mixed
Stress causes measurable microbiome changes that in turn affect behaviour and immunity

Welfare Considerations

Microbiome health is emerging as a welfare indicator and target for intervention. Dysbiosis - disrupted microbiome composition - is associated with inflammatory bowel disease, anxiety and chronic skin conditions in companion animals. Diet diversity, high-quality fibre, limited unnecessary antibiotic use and stress reduction all support microbiome health. Probiotic supplementation after antibiotic courses has theoretical but not yet consistently demonstrated welfare benefit. The microbiome-brain-behaviour axis means that gut health may be a welfare consideration beyond just gastrointestinal wellbeing.

What You Can Do

Discuss antibiotic stewardship with your vet - avoid unnecessary use to protect microbiome
Provide dietary fibre through vegetables and species-appropriate high-quality food
Consider probiotic supplementation during and after antibiotic treatment in consultation with your vet
Minimise stress events and chronic stressors that disrupt microbiome stability
Engage with emerging research on microbiome-informed nutrition and behaviour
