Original publication title: Treatment of recurrent hunting-associated respiratory distress episodes in 2 dogs.
Plain-English summary
Two hunting dogs experienced trouble breathing during and after hunting activities. They were diagnosed with a rare condition called noncardiogenic pulmonary edema, which causes fluid buildup in the lungs. One dog responded well to treatment with sympathetic blockers and no longer had breathing issues while hunting. The second dog, however, continued to struggle until it was treated with furosemide, a diuretic that helped prevent further breathing problems during hunts.

Abstract
Noncardiogenic pulmonary edema (NCPE) in hunting dogs is an uncommon and poorly described condition for which no preventive treatment is available. Two dogs were presented for recurrent respiratory distress strictly associated with hunting activities. Diagnosis was based on bilateral, symmetrical, interstitial-to-alveolar pattern in the caudodorsal lung fields on thoracic radiographs, exclusion of other causes, and spontaneous clinical and radiographic improvement. Considering that the pathogenesis of exercise-induced NCPE likely involves α- and β-adrenergic overstimulation, treatment with sympathetic blockers was used in both dogs. The first dog no longer showed respiratory signs during hunting activities. However, treatment failed to prevent respiratory distress in the other dog. Based on the large number of red blood cells in the bronchoalveolar lavage fluid of the second dog, exercise-induced pulmonary hemorrhage was suspected, as described in racing horses. The loop diuretic furosemide successfully prevented further hunting-associated respiratory distress episodes in this dog.
