Great Dane Growth Chart (with Pictures)

The Great Dane is one of the largest dog breeds on the planet.

Also known as Deutsche Dogge or German Mastiff, surprisingly the Dane doesn’t originate from Denmark – you guessed it, it’s German!

Assuming you already got your Great Dane puppy or are in the breach of deciding on buying one, it must certainly intrigue you how fast he/she is going to grow up.

You are in the right place because we are going to explain all the facts about Great Dane growth that might interest any Great Dane owner.

Why is it so important to know what to expect while your pup is growing up? – Simply because your dog’s health and well-being depend on the growth rate.

Great Danes are giant breed dogs. Like any other gentle giant, their bodies can experience episodes of extreme growth.

During those episodes, the muscular-skeletal segments might not properly align and thus different diseases occur.

Generally speaking, all big dogs are prone to hip dysplasia, elbow dysplasia, and hygroma.

The first two are hereditary diseases (although some other factors can worsen the symptoms), while hygroma occurs when the dog puts too much pressure on the elbows.

For now, let’s focus on what to look out for in your puppy.

The first and most important thing is never to compare your puppy to other puppies of the same breed.

There are always differences between two separate litters.

Moreover, there can even be significant height-weight fluctuations between individual puppies of the same litter.

A general recommendation is to buy a puppy from a reputable breeder that will let you meet your pup’s mom and dad.

Whatever the circumstances, juniors will have most of their physical traits.

As a buyer, you can ask for contacts of dog owners from previous litters and ask them about their own experience.

A responsible breeder will be more than happy to assist you in making the right decision and give you his views on the growth of the puppies.

Great Dane Growth Chart

The following growth chart shows numbers that are only estimates and can’t be taken as a single effective method in predicting the pup’s future.

They just tell you what the pup may weigh at a certain age.

If your dog is behind or ahead of these numbers, there is no need for concern.

All dogs are different and grow at different rates. Just continue feeding him quality food in carefully measured portions.

Also, keep in mind that there is a difference between American Great Danes and European Great Danes.

The American ones are smaller with narrow chests and smaller muscle weight.

European Great Danes are massive beasts. They have large chests and full, muscular bodies.

There have been some specimens that surpassed 240 lbs (108 kg) of body weight.

A certain height or weight goal is not something you need to strive towards but rather use as an approximate indicator.

If your puppy is stagnating with its growth don’t think that overfeeding or exercising too much can solve the problem.

Overfeeding can be especially harmful in giant breed dogs because obesity can trigger the health problems we mentioned before (hip and elbow dysplasia and hygroma).

Diet and exercise can spin the situation both ways.

Even though undernourishment is dangerous, fairly slimmer large and giant breed pups can avoid skeletal abnormalities in comparison to overweight pups.

During your dog’s life, you should only use quality food and follow strict feeding regimens.

The quantity of food, frequency of meals, and type of food change over time so make sure you know all the necessary facts.

Sometimes some puppies grow faster than others ultimately slowing their growth and ending up being the smallest of the litter.

If you have your eyes on a female baby you can expect her to be a bit smaller than her brother. 

For any concerns you might have your vet will help you either with a physical examination of the pup or just an informative talk.

Great Dane Growth Spurts

Great Danes grow in one year just as much as humans do in the initial 14 years of life.

Just like any other dog breed, they need to pass through growth spurts.

Keep in mind that during this period your GD pup might experience mild pain and also this is the time when dysplasia mostly develops.

The dog’s bloodline determines when the rapid growth phase will occur.

The biggest growth spurts are noted when your Great Dane is between 4 and 6 months of age.

Sometimes the spurts happen earlier, at about 3 months of age.

Remember when we said that a late bloomer doesn’t need to be the smallest dog from the litter?

That’s true because a growth spurt can start as late as 11 months of age.

Signs that your Great Dane is experiencing a growth stage are:

  • Frequent hiccup episodes
  • Sleeping more than usual
  • Painful reaction to touch
  • Loss of appetite
  • Fever
  • Weakness
  • Unexplained whimpering

Some symptoms are evident and some are not. For the most part, it’s nothing too serious to be worried about.

Because the Great Dane can gain 2 inches (5 cm) height within a week, his bones and ribs will become quite visible.

Diet can have a huge effect on the dog’s growth speed.

Feeding your Great Dane puppy food specifically for large breed dogs can assure they don’t go through massive growth spurts.

The good thing is that feeding your pup a large-breed puppy food won’t affect your dog’s adult size.

On the contrary, it can even promote it because the dog won’t go through all that stress and uncomfortable symptoms of rapid growth. 

Great Danes need a long time to fully develop. There are many classifications of their developing stages.

According to one, there are 4 stages of development based on the dog’s stature.

The first stage is the puppy stage (7-8 weeks).

The average height for female pups at this age is 14 inches (36 cm) and for males is 16 inches (41 cm).

They weigh between 18 and 23 lbs (8-10 kg) with females striving for the lower end.

During the first few months, the bones grow at faster rates.

The second phase is more for muscle growth and development. That’s why puppies are less muscular before they are sexually mature.

The second stage is when the dog already has half of the adult weight which is at about 5 months of age.

Males achieve a height of 27 inches (69 cm) and weight of 72 lbs (33 kg) and females are 24 inches (61 cm) tall and weigh around 62 lbs (28 kg).

8 months of age is the third growing stage in Great Danes. When they are this old they already have 80% of their adult body developed.

Between 5 and 8 months of age, the female puppies are expected to gain 24 lbs (11 kg) in weight and 5 inches (13 cm) in height.

For males, the growth rate is 28 lbs (12 kg) and 4 inches (10 cm) respectively.

The final stage is an adult Great Dane.

What Age are Great Danes Fully Grown?

Great Danes complete their physical development between 18 and 24 months of age.

Most dogs of this breed will already reach their top height at 18 months of age. Afterward, they continue bulking up with muscle until their second birthday.

How Big Will My Great Dane Get?

Full-grown adult female Great Danes weigh around 115 lbs (52 kg) and are 30 inches (78 cm) high. Male adults have 140 lbs (64 kg) of weight and around 32 inches (81 cm) in height.

As these numbers are average, some dogs can be above or below them. 

Some issues like shallow chest, straight legs, short muzzle, or roached back in puppies can reflect in their adult appearance, but that’s not a rule.

Some problems can also be medically treated so never miss out on consulting your vet if you have doubts about your puppies’ growth.

One method of prediction is to check the size of your pup’s paws and compare them to the rest of the body and the dog’s legs.

Oversized paws are considered a feature present in puppies that will have quite a growth ahead of themselves.

What is a Healthy Weight for a Great Dane?

The ideal weight for an adult Great Dane is between 115 lbs-140 lbs (52-64 kg).

The weight can only be ideal when it’s in correlation with the dog’s height.

For example, if an adult Great Dane male is 36 inches (91 cm) high, which is more than average, then 140 lbs (64 kg) is too little for the dog.

It’s important to acknowledge what lineage your Great Dane is coming from.

Does he have massive, bulky parents (and grandparents) or are they somewhat smaller?

Sometimes even big parents can produce somewhat smaller offspring.

Biological material, and in that manner genetic material, is a thing that constantly changes and adapts to new environmental conditions.

What you might see as an extremely large Great Dane or a Great Dane below the average proportions can simply mean that the dog is just a part of the next generation.

If you are concerned about your dog’s weight simply ask a veterinarian that has experience with giant breeds.
