A mystical Rainbow Dog converts gray, dreary towns with unhappy townsfolk into happy, friendly, colorful villages with welcoming citizens. As she strolls down the depressing Main Street, various shop owners rush outside to meet her. Once The Rainbow Dog hugs them, rainbows bloom around their hearts which transforms them.  A tiny, dirty mutt takes advantage of the townsfolk while they are distracted by The Rainbow Dog. The Rainbow Dog works her magic on the homeless mutt, too. They remain companions as they travel to other colorless, forlorn places spreading rainbows to all. THE RAINBOW DOG is a picture book of 361 words for ages 3-7.
