Great Dane

Also called Deutsche Dogge, German Mastiff

A dog the height of a small pony that would rather lean on you than guard anything.

Great Danes are enormous, gentle and surprisingly low-key indoors. Their size shapes everything about owning one, from the car you drive and the food bill to how carefully a puppy has to be raised.

Life with a Great Dane

Everything starts with the measurements. A male Great Dane usually stands 76 to 86 cm (30 to 34 in) at the shoulder and weighs 64 to 79 kg (140 to 175 lb). In practice that means his chin rests on your kitchen counter without effort, he fills the entire back seat of an estate car, and his tail clears coffee tables at exactly wagging height.

The breed was built in Germany from mastiff-type dogs and fast hounds to catch and hold wild boar, work that demanded both speed and mass. By the 1800s, German nobles kept the most impressive specimens as estate guardians and bedroom dogs, and in 1876 the breed was named Germany's national dog. The name Great Dane has no link to Denmark; it came from a French label that simply stuck in English.

Modern Danes kept the presence and lost most of the ferocity. A typical adult is polite with visitors, affectionate with family and content to spend much of the day stretched across a sofa. Many lean their full weight against people they like, which is endearing with a sturdy adult and hazardous next to a small child or an unsteady grandparent.

Practical life needs planning. You will want a bed at least 120 cm (4 ft) long, an extra-large crate, a vehicle with a low loading height or a ramp, and a vet practice comfortable handling giant dogs, since anesthesia, medication and surgery all cost more by the kilo.

What stands out

Puppy growth

Great Dane puppies grow at a startling rate. A pup of about 7 kg (15 lb) at 8 weeks can pass 40 kg (88 lb) by 6 months and still be far from finished. Most of the height arrives by 18 months, while chest, muscle and head keep filling in until 2 or even 3 years old.

Great Dane questions

Why is it called a Great Dane if it comes from Germany?

The name is a historical accident. In the 1700s the French naturalist Buffon described the dog as the grand danois, possibly because he had seen examples in Denmark. English speakers adopted a translation of his term and it stuck. In Germany the breed is the Deutsche Dogge, and most other European languages use a version of that name instead.

How tall is a Great Dane standing on its hind legs?

A large male on his hind legs often reaches around 2 m (6 ft 6 in) from paws to nose, which is why an enthusiastic greeting can knock a person flat. Females are usually a little shorter. Teaching a reliable four-paws-on-the-floor greeting from puppyhood is essential for safety, especially around children and older visitors.

Is harlequin a rare Great Dane color?

Harlequin, a white coat with torn black patches, is an accepted color but less common than fawn or black. It results from combining the merle gene with a separate harlequin gene, and pairing two merle carriers can produce puppies with deafness or eye defects. Choose a breeder who explains their color genetics openly and does not charge extra for pattern alone.

Can a Great Dane live in a small house?

Many do, because adults are calm indoors. What matters more is clear floor space for a big bed, a route to the car and garden without steep stairs, and furniture that survives a swinging tail. A ground floor flat beside open green space can work better than a large house surrounded by busy roads with nowhere to walk.

Why do Great Danes lean on people?

Leaning is usually a sign of comfort and attachment. A Dane presses its body against someone it trusts, rather like a hug. It can also appear when the dog feels unsure in a new place. It is harmless with steady adults, but teach a cue to step away so your dog does not topple a child or someone with poor balance.
