Holiday outings do not have to leave the dog behind. Tail of Lights turns Lakeline Park into a pet-friendly evening of seasonal music, glowing pathways and pictures with Santa Paws. Dress your four-legged companion for the costume contest, browse pet-related vendors and enjoy yappy-hour treats while meeting other local dog lovers. The illuminated walking path gives the gathering a relaxed pace, with plenty of reasons to stop along the way. Join the Cedar Park celebration from 6:30 to 8:30 p.m.
