The children's books that I write about Gus and Gunther are based on true stories about my puppies. This is the first coloring book of a series. We have our first picture book out The Adventures of Gus and Gunther how they met and will soon have a second picture book out of their first motorcycle ride. I got the idea of a coloring book from a little girl who read the first book and how she would love to color Gus and Gunther.
