Abstract
Heart disease is a disease that is quite common in dogs, especially small dog breeds. Most cases of dog heart disease are only recognized by the owner after an advanced stage i.e. the animal showed symptoms of prolonged cough and comprehensive examination at the clinic. The case study aimed to present the subclinical heart disease found in a young adult dog. This heart case was experienced by a 4-year-old male mini Pomeranian dog. This Pet was referred for a heart check-up because the referring doctor found an abnormal heart sound. After a comprehensive examination such as physical examination, thorax radiography, electrocardiography, and echocardiography was performed, abnormalities were found then confirmed the patient has a heart problem. From the results of the physical examination, there was no evidence of coughing, and no changed activity levels. There were normal retina vessels and mucous membrane color, also there was no changed of respiratory rate and effort. The results of the radiography examination showed a heart enlargement compared to normal. Electrocardiography (ECG) examination results showed abnormalities in the R-R interval and QRS complex. The ECG formed sinus arrhythmia. The echocardiography results showed thickening of the left ventricle wall and sinus bradycardia. From the abnormalities found in this dog, it was concluded that these animals had mild hypertrophy cardiomyopathy (HCM) disease. In this case, the patient should have regular heart check-ups to monitor the progression of the disease.
