About the Great Dane
The Great Dane is a muscular, elegant dog of enormous size, with a long, rectangular head and a friendly expression. It is known as a gentle giant: kind, loyal and affectionate with its family, and often convinced it is a lapdog.

Despite the name, the breed comes from Germany, where it has also been known as the German Mastiff or Deutsche Dogge. Its ancestors were heavier, more mastiff-like dogs used in the Middle Ages as high-status hunting dogs that hunted wild boar in packs.
The modern Great Dane developed in the 19th century, becoming taller and lighter, possibly with Greyhound or other large hounds added. Its nobility has earned it the nickname the Apollo of dogs. Although it has worked as a guard dog, today's Great Dane was bred for a gentle, docile nature.
Great Dane temperament
Great Danes are typically loving, playful and gentle, and they form strong attachments to their families. They can also be sensitive and may not adapt well to new situations, so early socialisation with different people, dogs and experiences matters.
They are not known for being excessive barkers, but they are quick to alert the family to strangers and can be territorial with unfamiliar dogs. With the right socialisation they usually get along with other dogs. A Great Dane raised with a cat should be fine with it, but the breed has a fairly strong prey drive, so introductions need care and they should never be left alone with smaller pets.
Great Danes love company and can struggle even with short periods alone. A lonely, anxious Great Dane may chew furniture and belongings.
Size and appearance
The Royal Kennel Club classes the Great Dane as extra large, and it is often described as the largest breed of dog. Adults typically stand 71–76 cm or more at the shoulder, with males reaching about 86 cm, and weigh around 46–54 kg.
The coat is short, sleek and dense. Breed standard colours are black, blue, brindle, fawn, harlequin and mantle. Merle is not a breed standard colour.
How much exercise does a Great Dane need?
Great Danes need at least two hours of exercise a day, spread across the day with walks and off-lead time in a secure area, plus free time in a large garden and training sessions. They also enjoy relaxing in front of the fire.
Puppies grow very fast, and too much exercise during growth can harm their bones and joints, so exercise must be limited while they are young. Great Danes need a lot of space indoors and out, do not suit flats or small homes, and need a large, securely fenced garden.
Training a Great Dane
Great Danes are intelligent and eager to learn, and are fairly easy to train for people who know the breed, although some can be a little strong-willed. Training matters because of their size.
- Start positive, reward-based training young and keep it consistent throughout their life.
- Teach good lead walking and a reliable recall early, as their size can intimidate people and other dogs.
- Train them not to jump up at people.
- Make socialisation a priority and keep it ongoing.
- If you are new to the breed, consider help from an accredited trainer.
Great Dane grooming
The short coat is low maintenance. A weekly brush, for example with a rubber grooming mitt, is usually enough to remove loose hair, with a little extra grooming in spring and autumn when shedding may increase. Great Danes are known for drooling, so they are not the best choice for very house-proud owners.
Living with a Great Dane
Great Danes can be tolerant, loving family dogs with the right training and suit active households. Because of their size, strength and powerful tail, they are not recommended for homes with younger children, as they can easily knock them over by accident.
Whatever the breed, dogs and young children should never be left alone together, and an adult should supervise every interaction.
Children
Usually better with older, calmer children.

Great Dane health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
Like many pure-bred dogs, Great Danes are at risk of certain breed-related conditions, and their lifespan is usually under 10 years. The Royal Kennel Club lists the breed in Breed Watch Category 2 for points of concern, and it also has a breed club health scheme. Knowing about these conditions helps you ask a breeder the right questions; it does not mean every dog will be affected.
Gastric dilatation volvulus (bloat)
The stomach twists. It is an emergency that needs urgent veterinary attention.
Hip dysplasia
The hip joint does not fit together properly, which eventually leads to arthritis. The Royal Kennel Club recommends hip scoring under the BVA/KC Hip Dysplasia Scheme.
Elbow dysplasia
The elbow joint does not fit together properly, which eventually leads to arthritis. The Royal Kennel Club recommends elbow testing under the BVA/KC Elbow Dysplasia Scheme.
Dilated cardiomyopathy (DCM)
A type of heart disease in which the heart becomes larger than it should be and does not work properly.
Inherited myopathy of Great Danes (IMGD)
A muscle-wasting disease seen in the breed. A DNA test is available, and the Royal Kennel Club recommends it before breeding.
Wobbler syndrome
Instability of the bones in the neck, which causes weakness in the back legs and an abnormal, wobbly gait.
Eye conditions
Great Danes can have eyelids that turn inwards or outwards (entropion and ectropion), glaucoma and cherry eye. The Royal Kennel Club recommends eye testing under the BVA/KC/ISDS Eye Scheme.
Cancers
Certain cancers are seen in the breed, including osteosarcoma, a serious bone cancer.
What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Great Dane home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Great Dane cost to own?
There are two costs: bringing a Great Dane home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically up to 10 years, not just the first year.
Buying a Great Dane
If you have decided the Great Dane suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Great Dane
Great Danes do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
