E-mail: firstname.lastname@example.org Dirofilariasis is an important zoonosis that is the domestic dog the major host. Although most animals is asymptomatic, possible laboratory abnormalities can be found. The aim of this study was to evaluate the hematology and serum biochemistry of dogs naturally infected with Dirofilaria immitis microfilariae, from the Algodoal Island, located in the state of Pará. Diagnosis was done by identifying microfilaria through the modified Knott method. Out of 82 animals, 53 (64.63%) dogs were found positive and 29 (36.34%) negative. On physical examination, all animals were asymptomatic. The main findings in hematology were normocytic normochromic anemia, thrombocytopenia, lymphocytosis and basophilia. In the serum biochemistry, only urea values were above normal levels. It was not possible to identify findings that are pathognomonic of infection in dogs. However, laboratory evaluations should still be considered for diagnosis and treatment.
