Abstract: Background: Dilated cardiomyopathy (DCM) is a progressive cardiac condition commonly seen in Labrador Retrievers, characterized by impaired myocardial contractility and arrhythmias. This case presents a 10-year-old male Labrador retriever diagnosed with DCM, exhibiting clinical signs of lethargy, exercise intolerance, and respiratory distress. Case Description: The dog was presented with severe respiratory distress, muscle wasting, abdominal distension, coughing, and decreased exercise tolerance. Physical examination revealed tachycardia, dyspnea, and ascites. A grade III systolic murmur was detected, indicative of mitral valve regurgitation. Laboratory findings showed mild anemia and marginal azotemia, and radiographs confirmed significant cardiomegaly (VHS 13.2). Echocardiography revealed severe mitral regurgitation, left ventricular dilation, reduced EF% (19.59%), and an elevated left atrium-to-aorta ratio (2.33). Electrocardiography showed atrial fibrillation with a heart rate of 180 bpm. Diagnosis: The dog was diagnosed with dilated cardiomyopathy with moderate systolic dysfunction. Clinical Management: The treatment plan included Pimobendan, Benazepril, diuretics, Diltiazem, Digoxin, taurine, L-carnitine, and a low-sodium diet to improve cardiac function and manage symptoms. Outcome: Significant clinical improvement was noted, with echocardiographic EF% increase. The patient’s heart rate and rhythm stabilized, and the overall quality of life improved significantly
