Great Dane Growth Chart

This is a complete guide on Great Dane growth. I am going to be sharing the average growth, weight and height charts that are expected for your pooch.

Here are some of the topics that we are going to cover in this guide:

So without further ado, let’s get started.

Great Dane Growth Chart

This section covers the average and expected growth rate of a Great Dane. However, you should remember that there are so many factors that influence growth and your own dog might slightly deviate from these averages even though they are healthy.

Here is a detailed chart showing the expected growth, weight and height of a Great Dane at various stages of their life:

1 year95-140 lbs29-36 inches
Adult (Male)135-170 lbs33-36 inches
Adult (Female)110-145 lbs30-34 inches

From birth, a Great Dane will continue to mature until the of 2 to 3 years old. Other Great Danes may be slightly taller over the second and third year and there are others that will pick up body weight during this stage.

So if your Great Dane slightly deviate in either direction from the average values provided in the chart you should not be worried. The final size of your Great Dane is dependent on many factors like genetics you may not be in full control of. Other factors like diet and nutrition also play a major role in determining the final size of your Great Dane.

It is important to provide a nutritionally balanced diet for your Great Dane if you want them to maintain the desired slow and steady growth.

The keyword is balanced nutrition. Undernutrition can lead to your dog having a low body weight and other diseases that are related to nutrient deficiencies. On the other hand, according to a study on the relation between nutrition and bone growth in large and giant dog breeds like Great Danes concluded that overnutrition in dogs from the larger breeds exaggerates this tendency to create osteopenia by increasing the rates of skeletal growth and remodeling of the newly formed cancellous bone.

The next sections will cover more about Great Dane weight, height and some of the factors that influence growth.

How Big Does A Great Dane Get?

Adult male Great Danes usually grow very big and can get to an average height of 33 to 36 inches and weight of 135 to 170 pounds. On the other hand, female Great Danes usually grow smaller than males and can get an average adult height of 30-34 inches and weight of 110 to 145 pounds.

As mentioned earlier, there are many factors that influence the final size that your Great Dane can get so you may find yours slightly deviating in either direction from these averages. The real problem and a reason for concern is when your dog is deviating from these averages by much bigger margins.

Great Danes usually grow very big and this is one of the reason why they were originally bred for hunting. A study on Great Dane history suggests that the breed was always large but what really changed was their aggressive temperament to become a gentle family dog.

When Do Great Danes Stop Growing?

Great Danes are mostly considered fully grown between the ages of 18 and 24 months old. A good number of Great Danes usually reach their full height by 18 months old and continue adding muscle and picking up more weight until they are 24 months old.

Factors like genetics, gender and nutrition greatly influence the final size of your Great Dane but many dogs across the breed will stop growing between the ages of 18 and 24 months old.

When a Great Dane is fully grown a male should not be less than 30 inches at the shoulders, but the preferred size is 32 inches or more and the shoulder size should be well proportioned to his height. The female shall not be less than 28 inches at the shoulders, but it is preferable that she be 30 inches or more, providing she is well proportioned to her height.

How Much Do Great Danes Weigh?

The average weight of a male adult Great Dane is between 135 and 170 pounds whilst an adult female Great Dane will usually weigh between 110 and 145 pounds.

There are different body-weight changes in puppies and dogs of different breeds. Here is an average chart showing the expected average weight of a Great Dane at various stages of their growth:

There are so many factors that will affect the final weight of your Great Dane but the major ones are genetics, gender and nutrition. If your dog slightly deviates from the averages in either direction then there is no need to worry. The real reason for concern is when your Great Dane is overweight or underweight.

If your Great Dane is underweight this might be a symptom of an underlying disease or condition so you will need to work closely with your veterinarian to determine the root cause. Here are some of the reasons why your dog might have a low body weight:

  • Exocrine Pancreatic Insufficiency.
  • Inflammatory Bowel Disease.
  • Diabetes.
  • Intestinal parasites.
  • Surgery.
  • Illness.
  • Thyroid Problems.
  • Anxiety.
  • Liver Disease.
  • Dental Problems.

Here are some of the signs of an underweight Great Dane:

  • Obviously visible ribs, hips or shoulders (note that some breeds typically have low fat reserves in these areas)
  • A reduced energy level and lack of enthusiasm.
  • Poor coat condition or reduced shine.
  • Depression.
  • Poor eating habits.

If the underweight problem is not being caused by an underlying condition or disease then poor nutrition might be the root cause. There is dog food designed for weight gain in large breeds like Great Danes and there are also dog supplements that can help your Dane to gain weight.

However, you should remember that puppies often take some time to start gaining weight and trying to make your puppy grow more quickly is never a good idea. It is greatly encouraged that puppies gradually grow at a natural rate for proper skeletal development.

One of the best dog food formulas for a Great Dane puppy is the Rachael Ray Nutrish Natural Beef that is made from natural ingredients with added vitamins and minerals for a complete and balanced nutrition. There is also natural prebiotics included to support a healthy digestion for your Great Dane puppy.

If your adult Great Dane is underweight the best option to help them gain more weight can be dog supplements. One of the best weight gain supplements for Great Dane dogs is the Dyne High Calorie Liquid Dog Supplement:

Obesity is also another problem for large breed dogs like Great Danes. In North America, 25-30% of the general canine population is obese. According to a study on the subject, obesity in dogs is attributed to several factors, including genetic pre-disposition, reproductive management and dietary/exercise (human) management.

The best way to reduce the risks of obesity and avoid your Great Dane being overweight is to provide a nutritionally balanced diet and regular exercises for the dog.

How Tall Do Great Danes Get?

The average height of an adult male Great Dane is between 33 and 36 inches whilst an adult female Great Dane can have an average height of between 30 and 34 inches.

Great Danes are one of the tallest dog breeds and the are many factors that affect their final height. Genetics, gender and diet seem to be the most contributing factors. Here is a chart showing the average height of a Great Dane at various stages of their life:

The best way to get your Great Dane to grow to their ideal height is to provide a nutritionally balanced diet that provides all the required nutrients for growth and a healthy lifestyle.

Biggest Great Dane Ever

The biggest Great Dane ever recorded was one named Freddy. Freddy held the tallest living dog for the male category before he passed away with 8 and a half years old.

According to the Guinness World Records, When measured by a vet and Guinness World Records’ Editor-in-Chief Craig Glenday, Freddy was a towering 103.5 cm (3 ft 4 in) from foot to withers. Standing on his hind legs – not a measurement that GWR officially counts – his height was an imposing 226 cm (7 ft 5.5 in).

Factors That Influence Great Dane Growth

As mentioned earlier, the final size of your Great Dane is affected by many factors. This section is going to cover a few factors that great influence Great Dane growth. They are:

Gender

Male Great Danes tend to grow much bigger than female Great Danes. This has a lot to do with the differences in hormone levels between male and female dogs. Other biological differences between male and female dogs will also affect the final size of the dog.

Genetics

Genetics is another factor that greatly contributes to the final size of your Great Dane. Every dog inherits certain qualities from their parents so ancestral history can also affect how big your Great Dane gets.

Diet

Diet or nutrition will also affect the final size of your Great Dane. It is important to provide your dog with a nutritionally balanced diet if you want them to reach their ideal breed size. A healthy Great Dane diet should have a high amount of proteins, moderate fats and low calories.

A study on the relation between nutrition with growth and skeletal development in dogs concluded that energy, protein, and calcium are nutritional factors of great importance to (skeletal) growth. However, it is important to provide an optimum amount of these nutrients as too little or too much can cause great harm to your Great Dane.

Another study on the growth and skeletal development of Great Dane puppies also concluded that feeding a dog of a large breed with a diet exceeding the National Research Council (1974) recommendations for energy, protein, calcium, phosphorus and vitamin D may result in disturbances of skeletal development.

It is important that Great Dane owners provide a balanced diet with the optimum amounts of nutrients if they want their dogs to experience a slow steady growth and reach their ideal size without any harm caused.

Summary

Great Danes are naturally large dogs that grow bigger. Adult male Great Danes can naturally grow to a height of 33 to 36 inches with an average weight of 135 to 170 pounds. On the other hand, adult female Great Danes are expected to have an average height of 30-34 inches with an average weight of 110 to 145 pounds.

There are many factors that affect Great Dane growth but the ones that greatly contributes to size are genetics, gender and nutrition.

The other two are mostly outside human control but Great Dane owners can significantly contribute to their dog reaching its ideal size by providing a nutritionally balanced diet with the necessary nutrients required for growth and maintaining a healthy lifestyle.

Great Danes normally require a diet with a high amount of proteins, moderate fats and low calories.
