For the proper fitting of most breeds, the measurement needed is taken from the tip of nose to the “stop” (just below the tear duct of the eye), as shown in Figure 1 below.
IMPORTANT: Be sure to add 1″ – 2″ to the circumference measurement of your dogs snout in order to account for pant room. Panting allows the dog to regulate body temperature, express anxiety/excitement, among other things.
