Background: Leptospirosis is probably the most widespread and prevalent zoonosis in the world, being classified as an emerging infectious disease for humans and dogs. Sporadically, dogs may present with cough and dyspnea, indicative of pulmonary involvement, associated with interstitial pneumonia and pulmonary hemorrhage with alveolar consolidation. Such changes stem from pulmonary haemorrhagic syndrome, which has emerged as a fatal complication, being documented in some areas in Europe and little described in North America. In this sense, the present study aims to report pulmonary hemorrhagic syndrome in a dog with leptospirosis.Case: A dog with no defined breed, aged 45 days, weighing 2.2 kg, with a history of apathy, anorexia, jaundice, hematochezia and vocalisation with a two day evolution was seen. Physical examination revealed a rectal temperature of 37.2°C, icteric mucosa, capillary filling time of two seconds, respiratory rate of 80 movements per minute and heart rate of 140 beats per minute, dehydration rate estimated at 8%, prostration, adequate body score, normal cardiac sounds and clean lung fields, in addition to petechiae in the abdominal region, whose palpation evidenced the presence of fluid in intestinal loops. The blood sample sent to the macroscopic serum agglutination was reagent for the serovar Icterohaemorragiae, titration of 200. Blood count revealed leukocytosis due to neutrophilia, with left-sided deviation, eosinopenia, presence of rare hypersegmentated neutrophils, rare toxic neutrophils, mild cytoplasmic basophilia and rare reactive lymphocytes. Platelet estimation demonstrated thrombocytopenia. No haemoparasites were seen. Regarding the biochemical evaluation, there were changes in liver enzymes and markers of renal failure. Fluid therapy was used with 0.9% NaCl solution, 5 mg/ kg doxycycline intravenously every 12 h and nasogastric probe for administration of nutritional support...(AU)
