There are many varieties of terrier including numerous celebrated breeds. The English, Scotch, Skye, Bull and Fox terriers being the best known. Innumerable stories of the intelligence and sagacity of the various breeds might be told if space permitted, but it must suffice to say that for sportsmanlike qualities, for general intelligence and sagacity, and for affection for his master, the terrier of whatever breed will hold his own against any other dog. Dogs are said to have natural antipathies, and that of the Bull-dog for the bull is an obvious illustration. An equal antipathy is shown by the English terrier for the rat and by the Fox-terrier for the cat, though the latter is perhaps as much a matter of education as of nature. Terriers are, however, among the best known of dogs and therefore need the less description.
