Chemical pneumonitis secondary to inhaled waterproofing shoe spray in a canine

Abstract

A 3‐year‐old, female, spayed, mixed breed dog developed progressive dyspnoea after exposure to waterproofing shoe spray. The dog developed severe hypoxaemia and hypercapnia, and was subsequently diagnosed with veterinary acute respiratory distress syndrome secondary to chemical pneumonitis. Mechanical ventilation was initiated due to respiratory compromise. Severe hypercapnia persisted despite aggressive treatment. Unfortunately, the patient experienced cardiopulmonary arrest non‐responsive to cardiopulmonary resuscitation. A postmortem examination was performed, revealing pulmonary haemorrhage, hyaline membrane formation and necrosis. These findings are supportive of a diagnosis of chemical pneumonitis secondary to inhalation of waterproofing shoe spray, resulting in acute respiratory distress syndrome.
