I was going to post this in the dog thread, but decided to post in this thread.
My daughter in law is a mobile dog groomer and she is in a 'pom' group in facebook. Every month or so they have an online dog coloring. This month's theme was woodstock, so the DIL decided on the Grateful Dead dancing bear. The coloring is vegetable based and is not harmful to the dog physically, but I am sure he is scarred mentally after each contest.
