Books like Wild Trek

Wild Trek is the sequel to Snow Dog. I liked the story of both, but Jim Kjelgaard's world view is depressing, to say the least. All of his books are like Jack London's- very interesting and enjoyable, but ultimately depressing. The only point in life is to survive. I liked the dog, because that's basically what a dog's point of view should be. I didn't like Link Steven's view, because that's not what a human should think. His partner contemplated the meaning of life, but I feel the author was somehow mocking that kind of inquisitiveness. Since the world view was the only think I disliked about this book,I would have only knocked off one star. However, since the world view of evolution was more or less shoved down the reader's throat, I knocked off two. Chiri is very lovable, so as long as he was around, the book was enjoyable.
