This book, originally published in 1925, narrates the adventures of the funny-looking purebred collie, named Wolf, who was somewhat an outsider with a matching personality. Describing in detail how he was raised at Sunny bank Kennels, it tells about his friends, how was trapped and rescued, his kidnappers, the mystery-show, and his last adventure. Wolf the dog himself became famous posthumously when his heroic death was recorded in nearly every paper in America.
