The result of clinical examination showed that there were 27 out of 825 dogs suspiciously infected with E. canis, accounting for 3.27%. The blood samples were collected from 27 suspicious dogs to examine with the test kit and blood smear assay to clarify the infection rate of dogs with E. canis. The studied results showed that 27/27 (100%) of suspicious dogs were positive with E.canis by the kit test. However, there were only 17/27 dogs harbored the mulberry embryos of E. canisdetermined from the blood. It indicated that the blood smear assay was necessary to confirm E. canis infection in dogs. The infection rate of dog with E. canis was independent on the dog breeders, gender, ages and tick infection state (P>

The common clinical symptoms of dogs infected with E. canis included hemorrhage on the abdomen, pale mucosa, vomiting, loss of appetite and weight, black stools, eye bleeding, mucus discharge, nosal bleeding. The treatment regimen for 27 dogs infected with E. canis was doxycycline and prednisolone used in 28 days and combined with imochem in the severe cases. The treatment efficacy was high with 88.9% of dogs were recovered.
