I and a number of my friends all have a dog called Spot.  He is our white dog to protect us from the Black Dog.  We can carry him round with us not only as a protection but as a reminder that each of us has a Spot.  In times of anxiety, I have held Spot tightly in my hand and really felt that I had my friends with me so I wasn’t going it alone.  Something so simple but so comforting.
