It is important to know the standard electrocardiographic values in each dog breed because of variety of body size and anatomical difference of the chest. Since Retrievers are originated from the hunting dog, their electrocardiogram (ECG) values might be different from standard normal range of the dogs. The purpose of this study is to determine the standard ECG of Golden Retrievers and Labrador Retrievers, and if their values of each ECG measurement are different from standard ECG values. Six-lead ECGs were taken from 57 Labrador Retrievers and 34 Golden Retrievers. Amplitude and duration of P wave and QRS complex, PR interval, QT interval and mean electrical axis were measured in each ECG strip. Labrador Retrievers showed deep Q waves in lead I, II and aVF. Golden Retrievers showed tall R waves in lead II and aVF. It was indicated that Retrievers had a specific shape of QRS complex. It is needed to notice the characteristics when diagnose ECG.
