Groin to Ground Measurement of a Dog for a Wheelchair

To measure the height of a dog for a Wheelchair, measure from the ground to the "Fold of the Flank" as shown here.  (The skin material that joins the rear leg to the abdomen).  The measurement does not need to be 100% exact because the cart is adjustable, however, if your measurement is wrong or taken from the wrong point, you may need to exchange the wheels.  You want to do the measurement from the side of the dog, not underneath.  In the picture of the live dog, the finger is pointing to the flank skin that joins the rear leg to the abdomen.  This is where you take the measurement from.
