The popularity and availability of echocardiography in veterinary practice for companion animals have substantially increased in recent years. The results obtained during the procedure are compared to reference values established for the general dog population or to standards developed for a specific dog breed. The aim of this study was to determine whether individual dog traits, such as body weight, chest structure, and level of physical activity and performance, affect the reference values for echocardiographic parameters. Published reference values for echocardiographic examination parameters for 32 dog breeds were analyzed and the relationship between individual echocardiographic parameters and body weight, chest structure, and level of physical activity and performance was then statistically analyzed. It was found that echocardiographic parameters are affected by the dog's weight and physical activity. There was no significant relationship between heart size and chest structure. The great variety of dog breeds means that echocardiographic findings should be individually interpreted rather than establishing reference ranges for each breed in population studies. This will allow for a more accurate interpretation of the results obtained in the echocardiographic examination and consequently lead to earlier diagnosis of changes in myocardial morphology.
