Toxoplasma gondii is an obligate intracellular protozoan. It has carnivores as hosts, among them, cats are definitive hosts and domestic dogs, intermediate hosts. Responsible for dermatological, ophthalmic and neurological alterations in canids. The aim of this study was to associate clinical and laboratory findings and risk factors with Toxoplasma gondii seropositivity in domesticated dogs. The analyzes were carried out from 47 dogs from the North Zone and Baixada Fluminense of Rio de Janeiro. Each animal had an individual form where information about anamnesis, physical examination and corresponding risk factors was stored. Blood samples were collected from the dogs by puncturing the cephalic vein and the serological diagnosis was made through the detection of in vitro antibodies to Toxoplasma gondii by the method of Indirect Immunofluorescence (IFIR) at the Laboratory of Parasitic Diseases, Department of Epidemiology and Public Health of Veterinary Institute of the Federal Rural University of Rio de Janeiro. Contingency tables were created, applying the G test, analyzing a possible significant association between risk factors associated with T. gondii infection in domestic dogs, at a significance level of 5%. A seroprevalence of 38,3% was identified in the population studied. Significant risk factors were the feline contact and the French Bulldog breed identified in the study. This study aimed to identify the soroprevalence and risk factors of toxoplasmosis in this population.
