A collar charm that lights up turns an ordinary December walk into part of the holiday. Mud Pie shaped each one in acrylic as a Christmas figure, with LED lights and a battery included, so it is ready to hang from a collar ring the day it is unwrapped. Add one to the stocking marked for the family dog, bring one for a friend whose pet is in every holiday photo, or put one on your own pup for the neighborhood lights tour.
