The genus Hepatozoon includes hundreds of species that infect birds, reptiles, amphibians and mammals, in all continents with tropical and subtropical climates. Two species have been described in domestic dogs: H. canis, reported in Europe, Asia, Africa, South America and the United States; and H. americanum, which so far has only been diagnosed in the United States. In Brazil, the only species found infecting dogs is H. canis. The objective of this review was to detail some aspects of canine hepatozoonosis, caused by H. canis, and the main points of its biology, transmission, pathogenicity, symptoms, epidemiology and diagnostic methods, with emphasis on research developed in Brazil.
