Hello and welcome to Petco Pet Education Center, formerly Petcoach. Blood pressure is fairly consistent across all dogs despite size, so about 120/80 (100) is the general 'normal' blood pressure. The circulatory pathway of blood is the same as well for all mammals. Body tissues --> veins --> through the liver --> caudal vena cava --> right atrium --> right ventricle --> lungs --> left atrium --> left ventricle --> aorta --> body tissues. Best of luck!
