Planet of the Dogs - Planet of the Dogs, #1

Out in space, on the other side of the sun, is the Planet Of The Dogs. Dogs have always lived there in peace and happiness. One day many years ago, the council of the elder dogs learned that there were problems on Earth, the Planet of the People. Many people had forgotten how to love and had become mean and greedy. The good people of Green Valley were threatened by the warrior tribes of Stone City.
The council realized that they needed help. This is the story of the first time dogs came to planet earth to teach people about love and to bring peace to Green Valley.
