The protagonist was born on another planet where he grew up fighting for survival. The cover pictured the dogs at shoulder high to a man and looking like a St. Bernard. It might have been a Science Fiction Book Club edition.
This is an omnibus of three novels all set on the planet Skaith: The Ginger Star, The Hounds of Skaith, and The Reavers of Skaith. Eric John Stark is the main character of each novel.
Stark was raised by non-human savages on Mercury, where he developed an extremely strong will to survive in an extremely challenging environment.
Also on Skaith are the Hellhounds, large beasts taller than a man, who are capable of telepathically projecting overwhelming fear onto intruders.
