"Buff A Collie and Other Dog-Stories" by Albert Payson Terhune. Published by Grosset & Dunlap, copyright 1921.
The strange adventures which befell Buff and Michael Trent needed courage and strong faith to bring them safely through. And Buff was no whit behind his master, for the finest of two breeds centered in him, the keenness and beauty of the blue-blooded collie and, far far back, the fighting heart of an indomitable pit-terrier.
