Abstract

A six and half year-old female Labrador retriever dog was presented to Teaching Veterinary Clinical Complex, Mannuthy with the complaint of anorexia, cough, weight loss, increased water intake and exercise intolerance. On clinical examination pale mucous membrane, dyspnoea, pulmonary crackles and cardiac murmurs on auscultation were observed. Thoracic radiograph revealed cardiomegaly, left atrial enlargement and pulmonary oedema. Increase in the duration of P wave (P wave width 0.06sec) was observed in electrocardiogram. Dilated cardiomyopathy was confirmed by echocardiography on the basis of left atrial and ventricular enlargements, increased left atrium/ aorta (LA: Ao) ratio, decreased systolic ejection fraction and fractional shortening. The animal was treated with furosemide (2mg/kg/q12h), enalapril (0.5mg/kg/q12h) and Top 10®, multivitamin, minerals and trace elements tablet orally. Condition of the animal was improved with the treatment.
