The gut microbiome plays a central role in dog health, immunity, behavior, and emotional wellbeing. Microbiome science is reshaping approaches to canine welfare and disease prevention.
The microbiome represents a frontier in understanding canine welfare. Dogs with disrupted microbiomes show increased anxiety, stress reactivity, and inflammatory conditions that significantly affect quality of life. Dietary choices, antibiotic stewardship, environmental exposure to diverse microbes, and probiotic support all influence microbiome health and by extension behavioral and physical wellbeing. The gut-brain axis means that chronic stress also disrupts the microbiome, creating bidirectional welfare impacts that require holistic management approaches integrating nutrition, behavioral support, and medical care.
