C) CIRCUMFERENCE OF CHEST
Measure all the way around the largest part of the chest, behind the front legs. (You may find it helpful to use a piece of string to take this measurement and tie it around the largest part of the chest then cut it off and measure from end to end.)
F) BASE OF TAIL TO BASE OF NECK
Place the tape measure at the base of the neck. Run the tape measure down the length of the back to where the tail meets the behind.
