Helpful tips

A & E should be equal to each other or with 1" difference.
C will always be smaller than B by 2-8", the taller and larger the pet, the bigger the difference.
For larger pets you can take A, B, C, E & H lying down with your pet on its side, back straight against the wall and legs straight down.
F & G are straight measurements NOT CURVED, place a hand on each side of your pets body and measure straight across from hand to hand.
