Abstract： Ehrlichia canis is a tick-borne pathogen transmitted by Rhipicephalus sanguineus s. l. ，primarily parasitizing the host’s blood cells. It poses a significant threat to human and animal health worldwide，and has considerable zoonotic importance. Several studies have found that the transmission and distribution of Ehrlichia canis is closely related to a variety of factors，including vector abundance， natural environment，age，usage，and health status of dogs. This paper provides a comprehensive review，covering the etiology，clinical manifestations，global epidemiological characteristics，and risk factors affecting the transmission and distribution of Ehrlichia canis. Its objective is to offer new perspectives and strategies for ehrlichiosis prevention and control.
