The Great Dane has been around for more than 3,000 years, dating back to ancient Greece. This breed was also found in Egypt and Rome.

Many sources suggest that the German Mastiff (Great Dane) was developed by crossbreeding Old English Mastiffs, Greyhounds, and Irish Wolfhounds.

Belonging to the Mastiff group (giant dogs), Great Danes possess incredible strength. They were once powerful enough to take down bears, wild boars, and other large animals. Originally, they were bred as guard dogs and draft dogs.

By the late 1600s, German nobles began keeping Great Danes as estate protectors.

In the 1800s, breeders continued refining the Great Dane, shaping it into the gentle and affectionate companion dog we know today.
