How does industrialization shape the gut microbiome of our oldest animal companions? 🐕🦠 New work from Laura Weyrich and colleagues finds that dogs’ gut microbiomes change with lifestyle and industrialization, while still retaining distinct host-specific features. www.biorxiv.org/content/10.6...

Industrialization restructures the domestic dog gut microbiome while preserving host specificity
Industrialization has reshaped human gut microbiomes, but its effects on other human-associated mammals remain poorly understood. Domestic dogs provide an informative comparative system because they h...
