The Great Dane, also known as the Apollo of dogs, is a giant breed. The Dane is German in origin, not Danish. Great Danes descend from mastiff-like dogs that were bred by German nobility to protect country estates and hunt wild boar. In the 18th century, Great Danes were prestigious guardians of estates and carriages.

Great Danes are considered gentle giants. They are moderately playful, affectionate and good with children. They will guard their home. Great Danes generally get along with other animals, particularly if raised with them, but some individuals in the breed can be aggressive with dogs they do not know.

Cancer is another leading cause of death in Great Danes, particularly lymphoma and bone cancer. They are also prone to a number of other skeletal, vision and neurological problems, both major and minor. Great Dane vet bills, like the dogs themselves, tend to be very, very large.
