context: There have been dogs like the Danish dog for millennia. In the territory of present-day Germany, large and strong dogs are known to have been kept since the 1960s. They have been used for war dogs and large game hunting, and later as protection and companion dogs for the Highlanders. The Danish Doggie's breeding is based on both old bullen beagles and wild boar hunting dogs. Originally, the word doggi was used to refer to a large and strong dog that was not necessarily of any breed. The show was first attended by doggies of this type in 1863 under the names 'Dänische Dogge' and 'Ulmer Dogge'. Most doggies at that time were blue, but there were also some isabella-colored and spotty harlequins. In 1878, breeders interested in the breed gathered in Berlin and named the breed 'Deutsche Dogge', or German Shepherd Dog. The breed's definition of race was confirmed at a meeting of judges in Germany in 1880. Eight years later a race organization, the 'Deutscher Doggen Club 1888 e.V. (DDC). "
