We describe the first reported case of grain-free diet-induced dilated cardiomyopathy (DCM) in a dog in Korea. An 11-year-old female dog was referred with abdominal distention, anorexia, and vomiting, having been fed a grain-free diet for more than 5 years. Thoracic radiography revealed cardiomegaly and pulmonary edema. Atrial fibrillation was detected using electrocardiography. The dog was tentatively diagnosed with congestive heart failure (CHF) secondary to grain-free diet-induced DCM, and its diet changed to contain grain. Digoxin and diltiazem were prescribed for the atrial fibrillation, and pimobendan, enalapril, and furosemide for CHF. Significant improvements in echocardiographic indices were confirmed after 3 months.
