But, despite their large size, Great Danes have become quite popular among dog owners. So, if you’re thinking of bringing home a Great Dane puppy, then you should be prepared for how big this breed will grow up to be. So, read on to know more about how big do Great Danes get.


The Great Dane breed originated in Germany; however, most people think that they have their origins in Denmark. Great Danes are called “Deutsche Dog” in Germany, which means “German Dog”; however, the rest of the world calls them Danes. These dogs were bred by Germans for hunting, but over the years, Danes have become domesticated and are now found in homes.

The Great Dane is actually a very old breed, which has been around for over 400 years. The earliest descriptions of the existence of dogs that resemble the Great Danes of today very closely date back to 1121 B.C. to China.

Appearance and Temperament

The appearance of the Great Dane combines its huge size and well-formed, powerful and well-muscled body with elegance, dignity, and strength. This working dog is unique in its appearance and has a courageous and spirited disposition that is always friendly and reliable. The physical, as well as mental combination, gives the breed majesty that no other dog breed possesses.

Great Danes are playful, yet gentle and show a lot of patience around kids, making them excellent family pets. These dogs love to please people and make friends very easily. These dogs are brave, fearless and quite unflappable. They are very calm and quiet and don’t bark often.

The only thing about the Great Dane is his size and you must be willing to handle this giant with loads of energy. Also, because of their size, Great Danes can be quite clumsy and can knock things and kids over, which means that need to be supervised constantly and require socialization and training. Not to mention that when you have a Great Dane, you need plenty of room.

The thing that you notice first about Great Danes is that these dogs are really huge. In fact, they are among the largest dog breeds in the world.

On his hind legs, the male Great Dane can be more than 6 feet tall and some dogs can even grow to 7 feet.

Size of the Great Dane Over Time

Typically, Great Danes grow quite a lot and very rapidly in their first year and if your Great Dane pup is growing very quickly, then it is a good sign. In this section, we have discussed the growth of a Great Dane puppy in the 1st year and this will give you a general idea of how your pup will look like when he’s fully grown.

Great Dane Size

  • 1 Month: Height – n/a, Weight – 5 to 8 lbs
  • 3 Months: Height – 17 to 23 inches, Weight – 25 to 45 lbs
  • 6 Months: Height – 26 to 33 inches, Weight – 65 to 100 lbs
  • 9 Months: Height – 28 to 34 inches, Weight – 85 to 125 lbs
  • 12 Months: Height – 29 to 36 inches, Weight – 95 to 140 lbs
  • Full Grown: Height – 30 to 36 inches, Weight – 110 to 170 lbs

A puppy who is smaller in size during the growth period most likely will be a smaller dog as an adult and similarly, a larger puppy will grow up to be a large-sized dog as an adult.

Are Smaller Great Danes Healthy?

You may find that your Great Dane is smaller than the sizes we have discussed above. If your dog is marginally smaller, then there is not much cause to worry. However, small Great Danes, as well as mini Great Danes do exist. Mini Great Danes are generally mixed breeds, the runt of the litter or may be a dog that has dwarfism.

Generally, it is recommended that you don’t get a Mini Great Dane because these dogs suffer from several health problems. If you’re looking for a Great Dane that is smaller than 30 inches, look for a mixed pup. These dogs generally are healthier and do not have as many health problems.

Training and Socializing Your Great Dane Pup

Because your Great Dane is a big dog, it is a good idea to train him when he’s young. Usually, Great Dane pups respond well to reward-based, positive training. This will help him to grow to be a well-behaved adult. You must teach your puppy not to jump on people, especially because your cute lil’ pup will grow to 100 pounds at least. And, you don’t want your Great Dane to jump on people for fun as an adult. By his sheer size, he could injure someone seriously without meaning to.

Often, Great Dane owners worry that the size of the breed will translate into aggression. But you don’t have to worry that your Great Dane will be ill mannered or aggressive. They have a mild temperament and are not aggravated easily. They protect both their owners and their home but are not a risk to humans and other dogs, especially if they have been introduced to them properly.

Nevertheless, it is recommended that you socialize your Great Dane puppy and introduce him to new experiences from a young age. This will help to reduce his nervousness, fear-filled responses and separation anxiety.
