My Great Dane Is Small, Should I Be Concerned?

If you experience decreases like one or two inches or pounds or even the same amount of increase in your Great Danes growth, there is nothing to worry about.

However, if you experience any significant differences or if your dog isn't meeting the standards of this chart, then it might be time for a check-up.

Consult your VET and find the underlying issue; anything can be a factor for an increased or decreased growth, it might be due to lack of exercise, or it might be anything. 

Remember that Great Danes need at least two hours of exercise every day, so it's super important to keep up with it.      

At What Age Will A Great Dane Stop Growing?

Great Danes grow quick enough that you can't even tell the difference between a 2-year and 4-year old Great Dane.

A Great Dane will be fully grown at the age of 1.5 or 2 years. However, this depends, and every dog is different.

After this, they will start to build up muscles.

A fully grown Male Great Dane will stand up to 32 inches and put up a whopping 175 lbs (79.3 kgs).  

While a fully grown Female Great Dane will stand up to 30 inches and will weigh around 140 lbs (63.5 kgs). 

The above numbers are according to American Kennel Club Breed Standard For The Great Danes.

Keep in mind that these numbers can vary according to each Great Danes.

However, if you feel that there is a major difference in the numbers, it's better to consult your VET.

What Is Weight That Is Considered Healthy For A Great Dane?

This depends on the age and what weight your dog's in.

For Context: A fully grown Great Dane Should weigh around 140 to 170 lbs. 

If it's more than the above numbers, it is considered unhealthy.

Otherwise, if your Great Dane is 30 inches tall and weighs around 200 pounds, it is too high for the dog.

Things That Affect The Growth In Great Danes

There are many factors to consider when it comes to the growth of a Great Dane.

But the two main things that affect the growth of your Great Dane is, as I said before, exercise and nutrition, these two play a significant role in your Great Danes, and if you see a decrease in growth, it's because of this. 


When it comes to feeding the Great Dane, many people think that the more food, the faster the growth.

It isn't really that way; if you're thinking that you're helping your dog to grow faster, forget it.

All you're doing is putting them at significant risk; overfeeding can introduce major health issues to your dog.

Keep in mind that a Great Dane grows at its own pace, no matter how much you feed them.

Follow a feeding schedule and get some instructions from your VET about feeding.  


Genetics, too, plays a huge role when it comes to the growth of a Great Dane.

Genetics determine the height, weight and almost everything regarding growth.


When neutered, a Great Dane can reach heights that are way more than the average numbers; this is because when neutered, the growth plates remain open for a more extended period of time, resulting in a significant increase in height. 

Not only that, but it also affects the overall growth rate.

Consult with your VET and discuss the possible effects and concerns; he'll help you determine the right time to neuter your dog.    

Great Dane Health Problems

The Great Dane can be plagued with health issues that can influence its lifespan and quality of life. 

One possible health issue that can come up for Great Danes is skeletal dysplasia, where they have abnormal development on their bones or joints. 

This ailment can make it difficult for them to physically move around and can alter how they walk or even cause paralysis in some cases.

According to the American Kennel Club, Bloat in Great Danes are the most problematic health issue and the number-one killer of Danes.

Other issues like thyroid issues and cardiomyopathy are also a concern for the Great Danes.

Great Dane Life Expectancy

Sadly, When it comes to longevity, the Great Dane is on the dark side.

Typically, A Great Dane is expected to live just 8 to 10 years, with some just 6 to 7 years.

This is due to their health problems and especially bloat. 


Great Danes are fantastic dog breeds; they're lovely, extremely affectionate and caring.

Before buying a Great Dane, you should know what you're getting into. This is a large dog and grows extremely fast, too; you must be ready.

I hope this Great Dane Growth Chart helps you. This is everything you can expect in a Great Dane's growth, so if you're ready to get one for yourself, GO AHEAD!
