Trust Your Dog

Why is this a problem?!!
Sometimes we make a muzzle and it arrives at its doggo and it is insanely small or large and when I recheck the photos of the measurements everything checks out just fine. So why would the muzzle not fit?
Well, sometimes a tailors tape measure gets stretched out OR isn’t set to a standardized inch or centimeter as you can see in this photo. The standard carpenters measuring sticks are solid but the tailors tape measure is off by inches right away causing the discrepancy when the muzzle arrives.
