The Eskimo dog is of medium size, and squarely built; in fact, he is a reclaimed wolf, and exhibits that variety of colour which, after a few generations, generally characterizes tame animals. Gray, which is often seen, was probably at one time the predominating colour. Some of the dogs are black, with white breasts; some are wholly white; others are reddish or yellowish; but, indeed, almost every shade may be seen amongst them. Their skin is covered with a coarse, compact fur, and is much valued by the natives for the purposes of clothing. In the form of the animals the variety is considerable; but the general characters would seem to be a pointed nose, short ears, a cowardly, treacherous eye, and a hanging tail. But exceptions occasionally occur, and one figures in Dr. Hayes’ narrative under the name of _Toodlamik_, or, more briefly, _Toodla_. He differed from his kind in having a more compact head, a less pointed nose, an eye denoting affection and reliance, and an erect, bold, fearless carriage. Dr. Hayes, however, expresses some doubt as to his purity of blood. From the beginning to the end of the cruise he was master of all the dogs that were brought to the ship. In this connection it is worthy of remark, that in every pack one dog invariably attains the mastership of the whole--a kind of major-generalship; and in each team, one who is master of his comrades, a general of brigade. Once master, always master; but the post of honour is gained at the cost of many a lame leg and ghastly wound, and is held only by doing daily battle against all comers. These could easily gain the ascendancy in every case, but for their own petty jealousies, which often prevent their union for such a purpose. If a combination, however, does happen to be brought about, and the leader is hopelessly beaten, he is never worth anything afterward; his spirit is completely prostrated, the poor fellow pines away, and dies at last of a broken heart.
