Inflammatory colorectal polyp (ICRP) is commonly observed in miniature dachshund in Japan.
Fecal microbiota was characterized by high-throughput 16S rRNA gene sequencing.
ICRP-affected dogs showed significant fecal dysbiosis compared with healthy dogs.
Microbiota of ICRP-affected dogs tended to change in composition to be similar to healthy after immunosuppressive therapy.
