This Dog “is probably an original breed peculiar to the British Islands.” It is larger than the Bull-dog, has a head of somewhat the same shape, with deep flews, but its ears are pendent, and it has none of the Bull-dog’s deformity. (See figure on p. 109.) From the Bloodhound it is distinguished by the shape of the head, which is rounder and shorter, and by the absence of the red ring round the eye. At the present day, the Mastiff is used chiefly as a house Dog, for which purpose his fidelity and strength make him thoroughly well suited. THE CUBAN MASTIFF is about intermediate in size between the Bull-dog and the English Mastiff; in appearance it closely resembles the latter. It is an extremely savage Dog, and was used in the days of slavery for tracking runaway negroes. It is now used as a watch Dog, and, by the Spaniards, for Bull-fighting. THE TIBET DOG. This magnificent animal is kept by the Bhoteas, a race inhabiting the table-lands of Tibet, who use it as a watch Dog. It is about the size of a Newfoundland Dog, but with a head more like that of a Mastiff, the “flews,” or pendent side-flaps of the upper lip, being of great-size. The hair is long, and the tail bushy and well curled. [Illustration: TIBET DOG.] Mr. Bennett says of some specimens kept in the Zoological Gardens many years ago, that they “were larger than any English Mastiff we have seen. Their colour was a deep black, slightly clouded on the sides; their feet and a spot over each eye alone being of a full tawny or bright brown. They had the broad, short, truncated muzzle of the Mastiff, and lips still more deeply pendulous.” In disposition they are--at any rate in their native country--“tremendously fierce, strong, and noisy; and while savage by nature, or soured by confinement, so impetuously fierce, that it is unsafe, unless the keepers are near, even to approach their dens.” This Dog was known to the Greeks and Romans, whose writers mention its fierce conflicts with the Aurochs, the Wild Boar, and even the Lion. THE ENGLISH TERRIER. This is a small Dog, with a good forehead, prominent eye, pointed muzzle, and usually short hair. The colour varies greatly--white and black-and-tan being perhaps the commonest hues; in the latter case, there is always a tan-coloured spot on the eye, a circumstance which it is interesting to remark, as a similar spot occurs in nearly all black Dogs with tan-coloured feet.
