measure your dog in two steps

    Measure the circumference of your dog's muzzle where you expect the goggle to land on their nose - usually around the back of their mouth.

  2. head circumference

    Measure the head circumference where you expect the goggle to land on the forehead - typically an inch or so behind the eyes.
