The 10 Facts About Great Danes

1. Great Danes Are a German Dog Breed

Great Danes are a German breed with ancestors that have been around for centuries. They descended from Mastiff-type dogs that were imported into continental Europe primarily from England. These ancient dogs were not a recognized breed and were known as “English dogs”. They were used to hunt bears and wild boars with the help of a huntsman. Their name was changed in the 19th century to “Deutsche Dogge” (German Mastiff).

Due to political tensions, their name changed to “Great Dane,” which was taken from their French name Grand Danios, or “Big Danish”. However, Great Danes are called “German mastiffs”; “Deutsche Dogge” in Germany. Great Danes were used by German Nobles who trained them to protect their country estates from intruders.

2. Great Danes Are Not a High-Energy Breed

You might expect such a large and intimidating dog breed to be very active. However, Great Danes are often fondly described as lazy and laid-back. Although their “lazy” disposition is normal for their breed, they still require regular exercise and playtime to keep busy. You don’t want your Great Dane to get too comfortable lounging around all day.

It's important to encourage them to be active. Most Great Danes have no problem snoozing for about 12 to 16 hours a day, especially if they have nothing better to do.


3. Harlequin Great Danes Are Incredibly Rare

Great Danes are available in various colors and patterns, with some being rarer than others. The harlequin pattern is caused by the interaction of the merle (M) gene with harlequin-specific genetic modifiers, resulting in distinctive cow-like markings.

According to the AKC breed standard, the Harlequin Great Dane's base color is white with torn black patches throughout. The breed standard mentions that merle patches are normal.1 There are also several mismarked Harlequin Great Danes, such as merle-patterned harlequins, blue-based harlequins, and so-called “merlequin” dogs, which are not recognized by the AKC breed standard.

4. They Were Believed to Repel Evil Entities

During the Middle Ages, Great Danes were believed to ward off evil entities. This is likely because of the protective nature that made them excellent guardians over the German nobility's estates. There was a belief that these dogs could sense supernatural entities and protect their owners from them. Some Great Dane owners would sleep close to their dogs to protect them from nightmares, too.


5. Great Danes Were Standardized as a German Breed

With their tall and muscular frames, gentle nature, and German origins, it's clear why Great Danes are closely associated with Germany. These noble dogs originate from Germany, and one of their original names, Deutsche Dogge, or “German mastiff,” is still used there. In 1878, a committee in Berlin officially standardized the breed under the name Deutsche Dogge.

6. Great Danes Naturally Have Floppy Ears

If you are used to seeing Great Danes with short ears, you might be surprised to know that their ears are naturally floppy. Their ears were historically cropped short when they were used as hunting dogs, as their ears were considered more vulnerable to injury when hunting wild boars. Cropping their ears helped prevent the wild boars from biting at them, and wasn’t for aesthetic purposes.

Although you might find some Great Danes have cropped ears nowadays, it isn’t as popular as it was decades ago.


7. Scooby Doo Is a Great Dane

The popular television show Scooby-Doo features a Great Dane as the main character. Production designer Iwao Takamoto was the one to design Scooby-Doo’s character in a similar way to Great Danes. Takamoto made sure to get the traits right by taking notes from a Great Dane breeder.

Scooby-Doo has a tall size, bowed legs, a sloped tail, and a sloping chin inspired by Great Danes.

8. Great Danes Are the Official State Dogs of Pennsylvania

In 1965, Great Danes were declared the official state dogs of the Commonwealth of Pennsylvania. They earned this title because of their historical presence in the state, where they were kept as estate guard dogs and companions by early settlers and prominent families. Great Danes have a noble history in Pennsylvania and were even depicted in the Governor's reception room painting.


9. Great Danes Are Found in 7 Official Colors

Great Danes are available in seven official coat colors recognized in the AKC breed standard. The AKC does not recognize additional colors, such as white and gray, as official colors or patterns.

10. They Are the Tallest Dogs in the World

Great Danes, as a breed, are among the tallest in the world, with Irish Wolfhounds typically slightly taller on average. However, the tallest dog on record was a Great Dane. The average Great Dane stands at a whopping 28 to 32 inches tall at the shoulder and can weigh up to 175 pounds. The tallest dog in the world was Zeus, a male Great Dane from Texas. Zeus stood at a staggering 41 inches (3 feet 5.18 inches) tall at the shoulder, according to Guinness World Records.
