Think I figured out trigger - however it may be to late to do anything about it. I'm really kicking myself. 11 year old son hadn't had significant tic waxing in nearly two years. After a year of consideration we recently brought a puppy into our home. My son has been waxing since we brought the puppy home. I'm so upset as I'm almost certain the puppy is the trigger. I will have to break his heart if I get rid of puppy. I feel so defeated. Thought we had this licked.
