Canine Gastrointestinal Microbiota Dynamics
Summary
The canine gastrointestinal tract hosts a complex and dynamic community of microorganisms that play pivotal roles in digestion, nutrient absorption, immune modulation and pathogen resistance. This microbial consortium, or microbiota, is dominated by bacterial phyla such as Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria, with diversity and relative abundances varying along the length of the gut. Throughout a dog’s life, factors including diet composition, age, breed, environmental exposures and health status shape microbial community structure and function. Stable communities maintain physiological homeostasis, whereas perturbations—termed dysbiosis—can predispose to gastrointestinal disorders such as chronic inflammatory enteropathy, acute diarrhoea and metabolic imbalance. Functional outputs of the microbiota include the production of short-chain fatty acids, essential metabolites that nourish colonocytes and regulate immune responses, as well as modulation of bile acid transformations and synthesis of vitamins. Recent advances in high-throughput sequencing and metabolomics have enabled integrated characterisation of microbial genes (metagenome), transcripts and metabolites (metabolome), revealing host-microbe co-adaptations and the potential for targeted nutritional or microbial interventions to restore equilibrium and improve canine health.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
