The Great Dane is a German breed known for its impressive size and strength, making it one of the two largest dog breeds in the world, alongside the Irish Wolfhound. Historically, Great Danes were used for hunting large game, such as bears, wild boar, and deer. Their role also extended to being guardians for German nobility. Over the centuries, the breed has evolved, but it still retains its majestic presence and noble lineage.
The Great Dane's ancestry dates back to the Middle Ages, where early ancestors of the breed were employed in hunting and guarding. These dogs were selectively bred from a mix of mastiffs and sighthound types, imported from England and Ireland during the sixteenth century by European nobility.

This strong, hardworking heritage gave the Rottweiler its reputation for power, endurance, and intelligence.
By the mid-19th century, the rise of the railway system led to a decline in their use for herding and cart-pulling. However, the Rottweiler's natural protective instincts, intelligence, and trainability led to its adoption in roles such as police work, search and rescue, and guard duties.
