No wood-dog, of any kind, has ever been known to attack man, and the hunter in the forest hears their bark in every direction without fear. It is, nevertheless, best to retire out of their way when charging sheep in packs, for they then seem seized with a blind fury, and some who have endeavoured to fight them have been thrown down and seriously mauled. But this has been in the blindness of their rush; no instance has ever been known of their purposely attacking man. These black wood-dogs will also chase and finally pull down cattle, if they can get within the enclosures, and even horses have fallen victims to their untiring thirst for blood. Not even the wild cattle can always escape, despite their strength, and they have been known to run down stags, though not their usual quarry. The next kind of wild wood-dog is the yellow, a smaller animal, with smooth hair inclining to a yellow colour, which lives principally upon game, chasing all, from the hare to the stag. It is as swift, or nearly as swift, as the greyhound, and possesses greater endurance. In coursing the hare, it not uncommonly happens that these dogs start from the brake and take the hare, when nearly exhausted, from the hunter's hounds. They will in the same way follow a stag, which has been almost run down by the hunters, and bring him to bay, though in this case they lose their booty, dispersing through fear of man, when the hunters come up in a body. But such is their love of the chase, that they are known to assemble from their lairs at the distant sound of the horn, and, as the hunters ride through the woods, they often see the yellow dogs flitting along side by side with them through bush and fern. These animals sometimes hunt singly, sometimes in couples, and as the season advances, and winter approaches, in packs of eight or twelve. They never attack sheep or cattle, and avoid man, except when they perceive he is engaged in the chase. There is little doubt that they are the descendants of the dogs which the ancients called lurchers, crossed, perhaps, with the greyhound, and possibly other breeds. When the various species of dogs were thrown on their own resources, those only withstood the exposure and hardships which were naturally hardy, and possessed natural aptitude for the chase. The third species of wood-dog is the white. They are low on the legs, of a dingy white colour, and much smaller than the other two. They neither attack cattle nor game, though fond of hunting rabbits. This dog is, in fact, a scavenger, living upon the carcases of dead sheep and animals, which are found picked clean in the night. For this purpose it haunts the neighbourhood of habitations, and prowls in the evening over heaps of refuse, scampering away at the least alarm, for it is extremely timid.
