In order to detect the prevalence of tick-borne pathogens in dogs, a total of 525 dog blood samples were examined by peripheral blood examination during different seasons. The survey was carried out from July, 2017 to June, 2018 in different parts of North-Eastern (NE) regions of India. Dogs were also closely inspected on their body surface for presence of ticks, if any. Out of 525 dog blood samples examined, 12.19% (64/525) were found positive for at least one type of tick transmitted pathogens as revealed by microscopic examination of stained blood smears. Twenty-eight dogs (5.33%) screened positive for Ehrlichia canis, eleven (2.09%) for Anaplasma platys, nine (1.71%) for Babesia gibsoni, eight (1.52%) for Babesia canis and eight (1.52%) for Hepatozoon canis. Dogs above two years age group showed higher rate of infection than dogs either between 1 and 2 years or below 1 year age group. Infection was higher during rainy season. Male dogs showed a higher proportion of infection than females. The only tick found during the study period was Rhipicephalus sanguineus. The results clearly indicate that vector-borne haemoprotozoa and rickettsia are prevalent in the study area in apparently healthy dogs without showing any obvious symptoms.
