The Great Dane is a dog which has at different times been called the 'boar-hound', the 'German Mastiff', and the 'Ulmer dog'. It first began to attract attention about 1870. The grand figure, the bold outlook, and the commanding appearance of the type commended it to certain enthusiasts; and when it was found to be faithful, and intelligent, and of unfailing courage, it soon came into favor. The latest development of the breed is a harlequin-colored or black and white dog, sometimes with a wall eye and mottled nose. The Great Dane stands 34 in. high, and weighs as much as 180 lbs.; though the bitch is considerably smaller and lighter.
