A split second later, to his vast astonishment, he saw the fox streaking back toward that part of the forest from which it had emerged. Since no squirrel dangled from its jaws, it was evident that the fox had failed to catch its quarry. Then a dog appeared, a half dozen bounds behind the terrified and madly-racing fox. The dog was light tawny in color, with no dark markings. About thirty-two inches high at the shoulder and six feet from tip of its black nose to the end of its tail, it weighed well over a hundred pounds. It was short-haired, square-faced, long-legged, and its tail was curled over its back. Lean of paunch, its shoulders were massive and blocky. Even had it been standing still, instead of running, its great power and strength would have been evident.

Franz smiled. The dog, an Alpine Mastiff, was his own Caesar. Three years ago he'd found it, a whimpering puppy, on the refuse heap where Emil Gottschalk had tossed it to die. Inch by inch, he had nursed it back to health.

He had learned a little of its history, and its roots went very deep. Originating in Asia, probably Tibet, many thousands of years ago, Alpine Mastiffs were brought to Asia Minor by silk merchants. Some fell into the hands of the early Romans, who used them as war dogs. When the Romans crossed the Alps, they took a number of these mastiffs with them. Some became hurt, or a female might give birth to puppies. These were left behind, simply because the marching columns could not afford to be slowed by them. And so, after thousands of years, the Alpine Mastiff found in the Swiss Alps a land very like the Tibet of its forefathers.

Caesar had an almost uncanny ability to adapt himself to the mountains. His huge paws supported him where another dog would have been hopelessly mired. At the height of winter, with Franz on skis and Caesar trailing alongside or behind, the two went where they willed and always safely.

Should the snow be soft, Caesar plowed his own path with his tremendous shoulders and never experienced the least difficulty. Even when all the rest of his body sank out of sight, Franz could always tell where he was by looking at the tip of his tail.

Let the wind blow as it might, and alter the outward appearance of the snow as it would, Caesar still knew the safe trails. He had an inborn foreknowledge of impending avalanches and a feeling for unsafe ice. When the brothers Karsmin were caught in an avalanche and buried beneath seven feet of snow, Caesar found them when all humans failed. Franz was satisfied that the dog had heard their hearts beating.

For all that, Dornblatt had no extra food for dogs. Franz never would have been allowed to keep Caesar had the animal not proven his worth. When the snow lay too deep for any horse or ox to venture forth, it was Caesar who dragged in the firewood. His back could carry as heavy a burden as two strong men were able to bear, so, even though Franz was the only human who could handle him, Caesar earned his way.
