Albert Payson Terhune 
Bruce [PDF ebook] 

As a respected dog breeder whose famed collie line is still winning awards today, Albert Payson Terhune knew the value of a perfect canine specimen whose attributes were sure to win plaudits at the top shows. But as a tenderhearted dog lover, Terhune recognized that all pups — not just the pretty ones — offer something of value to their owners. This fantastically action-packed novel centers on Bruce, a collie that wasn’t blue-ribbon material, but whose loyalty and bravery mattered more.
