Obesity in dogs, nowadays, increases as the rate of obesity in the world population grows, due to the intimate contact of these animals and humans. Associated to the accumulation of grease in the subcutaneous, fat is deposited between viscera and inside some organs, such as the liver. Liver fatty infiltration is present in the majority of obese individuals and, in humans, it is known that it progresses to severe forms of liver disease, cirrhosis and liver failure. Thus, two-dimensional and Doppler sonography act as valuable tools on detection and monitoring of fatty infiltration of the liver by mapping hepatic vein wave, analyzing velocity and volume flow of portal vein and blood flow velocity of hepatic artery. In dogs, there are few studies of the correlations between obesity and liver disease and its consequences in two-dimensional and Doppler ultrasound of the liver. This study aims to determine the hepatic parenchymal and hemodynamic changes, using B mode and Doppler sonography of overweight and obese dogs which do not have liver disease from other causes.
