How a dog's diet shapes its gut microbiome

Studies of the gut microbiome have gone to the dogs -- and pets around the world could benefit as a result. In a new paper, researchers report that the ratio of proteins and carbohydrates in a canine's daily diet have a significant influence on the balance of microbes in its gut. Researchers observed that dogs fed a high-protein, low-carbohydrate diet had enriched microbial gene networks associated with weight loss in humans.
