Thirty adult healthy dogs (11 males and 19 females) weighing 4.7 to 17.2 kg (mean 10.9±3.3) were studied by spectral Doppler echocardiography. All tested subjects were mixedbreed companion dogs with the age ranging from 1.3 to 8 years old. During recording, dogs were kept in left lateral recumbency without giving any chemical restraint. Blood flows across mitral, tricupsid, pulmonary, and aortic valves were analyzed to understand ventricular systolic and diastolic functions and pressure determination as well. In addition, cardiac output and ventricular stroke volume were calculated. Each set of data was validated with both normality test and descriptive statistics. Parameters were also evaluated to understand whether they were correlated to age, gender, heart rate, body weight, and/or body surface area. The results revealed that Doppler values were correlated to pressure recordings, systolic time intervals, indices of ventricular diastolic function, cardiac output index, and/or stroke volume index. In conclusion, the presented reference values are useful especially when the tested dogs are fitted in the above categories. And the facts that many values either not correlated to age, sex, or body size, appear to be good general references for evaluation of cardiac function for all dogs.
