Girth = measurement around widest part of rib cage. The Girth/Chest measurement is the most important measurement as the pack must fit snuggly to stay stable.
Length = suggested minimum dog length; measurement from base of neck to base of tail. If your dog is shorter than this length the size is probably not suitable.
