The canine gut microbiome as a translational model for human health and aging.

The canine gut microbiome shares significant taxonomic and functional similarities with humans, making dogs a valuable model for microbiome research related to health and aging.

• Why it matters: Understanding the canine microbiome addresses gaps in translational research by providing a clinically realistic model that reflects human health conditions, including chronic diseases and aging.
• What they did: Researchers evaluated the suitability of dogs by analyzing microbiome similarities, disease models, and study design considerations across 100–150 words, emphasizing clinical relevance and limitations.
• The result: Findings suggest dogs are especially useful for studying microbiome-related diseases and aging in realistic settings, but their use requires careful consideration of breed, diet, and genetic variability to maximize insights.
