This study aimed at describing several factors related to positive testing of dogs for visceral leishmaniasis, in an endemic area of the state of Rio Grande do Norte. Sera of 198 dogs were analyzed, 62 from rural properties and 136 from urban residences. Diagnosis was performed through indirect immunofluorescence and enzyme-linked immunosorbent assay. Forty five percent of positive dogs were from the rural area and 35% came from the urban area. Concerning the analysis of dogs' function, the watchdogs showed greater prevalence, with 50% prevalence in the rural area and 43% in the urban area. With regard to contact with other dogs and origin in rural or urban areas, the prevalence was 54% and 32% respectively. In relation to gender, females from the rural area were more prevalent. These results suggest more attention should be paid to dogs as reservoirs for this zoonosis, as well as their important role in the urbanization of Leishmaniasis and in epidemiological survey of the disease. These data can contribute to the planning of strategies for control, targeting dogs as domestic reservoirs.
