In order to give acupressure to yourself, your pets or, for those people who work with wild animals, wildlife, one must understand the basic anatomy of each species. This article touches on comparative anatomy.
In most cases all mammals have the same parts. Because humans are erect our anatomy is structured accordingly. Bovines, equines, canines, felines and rodents all have fairly similar anatomies and once you understand one you can easily understand others.
While humans walk on the soles of their feet, hooved animals walk on their toe nails. The ball of the foot in humans have adapted to the fleshy balls at the back of the hoof called frogs. Dogs, cats and rodents walk on their pads, which corresponds to the fleshy tips of the human toes and fingers. The meridian channels meet at the toes and fingers in humans, on the pads in canines, felines, etc., or the coronet band above the hoof.
The human knee corresponds to the stifle of four footed animals. This is located at the base of the hind legs next to the body. As in humans it can be an area of weakness for active animals like jumping horses or dogs that compete in agility.
The elbow on the human body corresponds to the elbows of most animals located at the top of the foreleg next to the body. This is another part of the body subject to stress.
Milwaukee pet owners and those people working with wild animals can find more information on comparative anatomy at the University of Wisconsin, Marquette University and Milwaukee Academy of Medicine.
