These dogs were initially bred for boar hunting and are known to be swift, alert, courageous, friendly, and dependable. The Great Dane is the tallest of the working breeds.

What does a Great Dane look like?

The Great Dane is a large working dog that originated in Germany over 400 years ago as a boar hunter. They are known to be swift, alert, courageous, friendly, and dependable dogs with a massive, square-jawed head and an elegant appearance. Great Danes have short coats that come in a variety of colors such as black, fawn (golden brown), brindle, blue-gray, harlequin (white with black patches), or mantle (white with a black "blanket" extending over the body). Fawn and brindle Great Danes usually have a black mask. As one of the tallest working breeds, Great Danes can stand 28–32 inches (71–81 cm) tall and weigh 110–175 pounds (50–79 kg).

What kind of temperament or personality do Great Danes have?

The Great Dane is often called a "gentle giant," which accurately describes its temperament. They are generally friendly and affectionate to family and strangers. Great Danes have a fairly low energy level and are playful but ready to stop after a short time. While not quick responders, they are easy to train. They make intimidating watchdogs and fair protection dogs. Great Danes are usually friendly toward unfamiliar dogs and get along well with housemates, and they do not bark without reason. Although their temperament makes them an excellent choice for people of all ages, a Dane’s size and strength can be too difficult for children or seniors to manage.

What are some common health concerns for Great Danes?

Great Danes, like other dogs, are susceptible to common ailments such as fleas and ticks and internal parasites. They are also prone to gastric dilatation volvulus (GDV), a bloating condition where the stomach twists, requiring immediate veterinary intervention. Cardiomyopathy and hip dysplasia are also common in Great Danes, with the latter being influenced by growth rate, exercise, nutrition, and hereditary factors. Additionally, merle dogs can have serious hearing and vision problems if bred together.

What should owners know about caring for a Great Dane?

Great Danes need a lot of space to stretch out and sleep, ideally on soft bedding to prevent calluses. Due to their size, everything from food to vet visits is more expensive. They aren't overly active but need at least one hour of interactive play or walking daily. Avoid runs until they are two years old to protect their developing bones. Great Danes enjoy games, hiking, and trick training. Weekly brushing is enough, but daily brushing is required during shedding season. The breed is prone to bloat, which can be fatal, and smaller meals throughout the day can help prevent this. Cardiomyopathy is also common. Great Dane puppies should be fed food that slows their growth to reduce the risk of hip dysplasia. They are friendly and affectionate, easy to train, and good watchdogs. However, their size and strength can be hard for children or seniors to manage.

Great Dane, breed of working dog developed at least 400 years ago in Germany, where it was used for boar hunting. The Great Dane is typically a swift, alert dog noted for courage, friendliness, and dependability. It has a massive square-jawed head and body lines that give it an elegant appearance. Its short coat is black, fawn (golden brown), brindle, blue-gray, harlequin (white with black patches), or mantle (white with a black “blanket” extending over the body). The fawn and brindle dogs have a black mask.

The Great Dane is the tallest of the working breeds. Its name was derived from one of its French names, Grand Danois (“Big Danish”), although there is no known reason to associate Denmark with the history or origin of the breed. In Germany, the breed is called the Deutsche Dogge (“German Mastiff”).

Did you know?: According to legend, Great Danes were the Ghostbusters and Scooby-Doos of the medieval world, reportedly set loose on properties to scare off evil spirits. A favorite breed in media entertainment, these gentle giants—one of the tallest dog breeds—have also had starring roles in the comic strip Marmaduke and in the Disney film The Ugly Dachshund (1966). The Great Dane is Pennsylvania’s official state dog.

Care and upkeep

The Great Dane’s size is the major challenge to its upkeep. The dog requires a large area in which to stretch out and sleep, preferably on soft bedding to avoid callouses. It also needs a big vehicle in which to travel. Owners should have an emergency stretcher or other plan in case they need to take an incapacitated Dane to a veterinarian. Everything costs more with a giant dog, including food, drugs, surgeries, boarding, and bedding. Many Great Danes also tend to drool a great deal, so they may not be the breed of choice for fastidious housekeepers.

The Great Dane requires an enclosed yard with a fence at least 6 feet (2 metres) high, although it is not a great jumper. Not excessively active, it still needs at least an hour of interactive playing or walking each day. To prevent damage to their developing bones, Danes should not be taken for runs until they are at least two years of age. The breed enjoys games of tug, running, hiking, and trick training. While some compete in agility competitions, a Great Dane’s size makes many of the standard obstacles very challenging. It prefers temperate weather, as it has little coat cover. However, because Danes are so large, they build up heat more quickly than smaller dogs.

Coat care is minimal, consisting of weekly brushing. However, during shedding season, brushing should be done daily. In countries where ear cropping is legal, the procedure requires considerable post-op care and taping to prevent infection and to train the ears to stand.

Danes do not live long, averaging only 7 to 10 years. The breed is prone to gastric dilatation volvulus (GDV), a bloating condition that is potentially fatal and can require immediate (and often costly) veterinary intervention. Many owners elect to have the dog’s stomach surgically attached to the abdominal wall in order to prevent the more severe complications associated with GDV. In addition, smaller meals served throughout the day can lessen the chances of developing the condition. Cardiomyopathy is also a common problem in Great Danes. Like puppies of all large breeds, Great Dane puppies should be fed a large-breed puppy food that slows the rate of growth, which has been shown to lower the risk of hip dysplasia.

Merle dogs (those born with the special gene that can produce unique patchwork dapple-spotted coats and even striking blue eyes) should never be bred to one another. The resultant “double merles” (homozygous merles) can have serious hearing and vision problems.

Temperament

While “gentle giant” may be an overused phrase, it aptly describes the Great Dane. Though large, it is generally friendly and affectionate to both family and strangers. Danes have a fairly low energy level, and, while playful, they are ready to quit and do something else after just a little while. The breed is easy to train but is not a quick responder. It is an intimidating watchdog and a fair protection dog. Great Danes are usually friendly toward unfamiliar dogs, and they get along well with housemates. The Great Dane does not bark without reason. Although its temperament makes it an excellent choice for people of all ages, a Dane’s size and strength can be too difficult for children or seniors to manage.

These are well established and widely accepted generalizations about the breed. Individual dogs may differ in behavior and temperament.
