This case report describes a 6 year old male Dobermann referred to our clinic (Istanbul University, Faculty of Veterinary Medicine) with compleints of shivering, polydipsia, sneezing, chronic dry cough, mouth breathing, apathie and diagnosed with echocardiography as Dirofilariasis based on the clinical and laboratory examinations in Turkey. Clinical pathological irregularities in pulse rate (60/min), respirations number (78/ min), and capillary refill time ( >2sc), while haematologic values of the case were between the reference intervals. CK (554 IU/ L) and LDH (763 IU/L) enzyme activities were high. Electrocardiographic examinations indicated deep Q (-1mV / lead II) and S waves (-1 mV / lead II), P-pulmonale (3mV / lead II) and notching in R waves, where, echocardiographic examinations revealed right atrial and vent-ricular dilatation with mature D. immitis bodies at the pulmonery artery, right ventricule and right atrium. In conclusion, we suggest that routine echocardiographic examinations will be beneficial in confirming D. Immitis sus-picion based on clinical and electrocardiographic evaluations.
