Abstract

A 2-year-old male mongrel dog was presented because of the onset of dry cough. About 16 hours before, the dog had been exposed to the pesticide that the owner was spraying in the vineyard. Approximately 3 hours later an acute respiratory failure, with a rapid evolution, began. Hemoptysis and regenerative normocytic normochromic anemia arose within hours, and a pulmonary hemorrhage was diagnosed. Pulmonary hemorrhage fast led to pneumonia, as evidenced by the serial CXR findings and the developing of leukocytosis. The hypothesis that we believe more likely is that the dog inhaled an amount of copper sulfate powder enough to determine respiratory tree damage, extending from the trachea to the pulmonary alveoli. Oxygen supplementation, antibiotics, antioxidant, and gastroprotective medications had been administered. After 4 days of hospitalization the dog was discharged. After a follow-up of more than 2 years later, the dog is still alive and in good health. To the authors knowledge no evidences of acute pulmonary involvement after copper sulfate inhalation exist in any species. This report is a contribution to the knowledge of copper poisoning, scarcely mentioned both in human and veterinary literature, and which has never been described in companion animals.
