The Newfoundland is an excellent watch-dog; sagacious in discriminating between a friend and a foe, and with courage and strength to follow out his prompt and judicious conclusions. He is easily trained for the drover, to whom he is frequently a great assistant; and with a scent sufficiently acute to pursue game, he is readily broken in as a useful companion to the sportsman. He can also be made serviceable in the various duties of the farm: destroying noxious vermin, taking the cattle and horses to the field or water, drawing a light load, churning the butter, &c. It is true, he has not all the sagacity of the Poodle, whose intelligence approaches nearer to human reason than any other of the brute creation. But if he has not that quick apprehension, which too often leads, as in the case of forward children, to the attainment of every worthless accomplishment and the indulgence of every loaferish habit, he seems to have a sedate, well-formed judgment, which makes all his wit available for some useful purpose. He is unsurpassed as a water-dog; and his courageous efforts, wherever an opportunity has been afforded, in rescuing numberless human beings from a watery grave, together with his unswerving fidelity and devotion, commend him as the prince of the canine family. The Shepherd's Dog. This animal, of which we give a beautiful portrait on the next page, of the long-haired Scottish breed, belongs to the same family as the Newfoundland and Poodle, which embraces the most intelligent and useful of the canine species. There are two classes of these dogs, which differ widely in their size and characteristics. The larger is of great size and courage, and when protected by a stout leather collar studded with spikes, is a full match for the wolf. These are used by the Spanish and Mexican shepherds, on their wild sierras, as effective guards against the attacks of all marauders, and are essentially the same race as the far-famed dogs of Mount St. Bernard. They are not sufficiently gentle for guides, and the shepherds who employ them rely on some well-trained wethers or goats to lead the flock at their call. Some have been imported into this country, but on account of their headstrong and ferocious character, and occasional depredations upon the flocks, they have been found unsuited to our wants, except on the borders of the wilderness.
