The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. The liver consumes about 20% of total body oxygen when at rest, so the total liver blood flow is quite high. Blood flow to the liver is unique in that it receives both oxygenated and partially deoxygenated blood.
Mini-Aussie Ideal Weight. I have a 3 year old female Miniature Aussie and she currently weighs 30 pounds. She gets moderate exercise (2 mile brisk walk each morning; chasing rabbits, birds, etc around a 1 acre yard).
My two rescue Scotties have very different builds, and weigh 9kg and 13kg. The bigger guy was 15.4kg when he first came to us, but with a sensible diet and plenty of excercise is now a much healthier weight with a waist. The little fella is just much more petite and has recently been mistaken for a lady Scottie!
