You already have the tallest dog breed in the world—so why would you need a Great Dane growth chart?

However, if you’re a first-time owner of this type of dog, you might have the question, “When do Great Danes stop growing?”. This is totally normal! Especially as puppies, their impressive, quick growth spurts can mislead you.

However, knowing a bit more information about when a Great Dane will stop growing can help prepare you for what’s to come so you can help control their diet and exercise.

In this article, we’re going to go over some pretty important sub-topics.  

When Do Great Danes Stop Growing 

When Do Great Danes Stop Growing

Fortunately, if you get a Great Dane as a pup, you’ll be able to monitor their growth through a specific growth schedule so you can ensure everything is going as it should be!

But for the answer to the most important question—when do Great Danes stop growing? Well, this “puppy” typically slows down with his or her growth around 18-24 months, both in height and in weight.

Full height is typically reached around a year and a half, while the pup can still pack on the pounds well into his or her second year.

Great Dane Weight Chart and Height Chart 

We’ve included a Great Dane weight chart that you’re now able to access so you can monitor your Great Dane’s weight more carefully. This can help you see whether or not your dog is growing and developing as he or she should!

When your dog goes to visit his or her vet, they’re going to be measuring the height and weight of your Great Dane anyways—however, it’s always a great idea to do so at home to have a record.

For the weight and height chart below, you’re able to see the column on the left, solely dedicated to the age of your Great Dane. As you move across the Great Dane growth chart, you’ll then be able to estimate how heavy they should be at the stage and how tall they should be as well.

Most adult Great Danes reach their full height at one year old. Although they technically tend to gain weight long after that first birthday, you’ll be happy to know that they’re not going to grow any taller! However, as their insides solidify and get more and more structurally sound, the weight will most likely shift.

You might notice that your Great Dane will get just a bit taller during this time—this is normal! However, don’t expect them to have any major growth spurts after the first year.

Please use the chart below to monitor the development of your Great Dane.

How Height Is Measured For A Great Dane 

Especially due to your dog’s large size, you might not be able to measure your dog’s height with a ruler or in the same way you would with a tiny pup.

When your dog is quite small, keeping them in one place hard enough to be able to measure their height. However, fortunately, weight is much more important than height to track the development and progress.

So, how do you do it? You might have heard that the Great Dane is measured from the bottom of their paws up to the tips of those perky ears. However, the right way to do is to measure from the bottom of their paws to the highest peak on the shoulder blades. 

If you’re trying to measure the height of your Great Dane on your own at home, you can get an accurate reading similar to how you would do it with your human child—by having him or her stand against a blank wall. The important thing here is that your pup stays still—which can be prompted with treats.

Make sure the measurement is taken at the top of the withers, which is the ridge between the shoulder blades—which is considered the tallest point of the body of a dog or a horse. Once you make that mark, you can measure from the floor to that mark—and you’ll have your height measurement!

Great Dane Growth Chart – What to Expect 

As your pup grows, there are certain things to expect in every stage of development. 

Great Dane Growth Stages

Stage 1: Birth – 2 months

At the newborn stage, your Great Dane is going to be a pretty cute—but pretty big “puppy”. At this stage of development, you can expect your puppy to reach up to 42 cm in height, which is almost 17 inches!

Although you might feel like you’re missing out on the puppy stage here since you have a rather large dog breed, they’re still going to be pretty darn cute with those big paws and ears to grow into!

You can also expect your pup to weigh around 39 lb all the way up to 57 lb—or 18–26 kg!

Stage 2: 2 months – 5 months

Once your Great Dane reaches five months, he or she should be at around 50 percent of their full height and weight. You can expect them to be around 27 inches in height (over 2 feet!) and weigh up to 80 lb in weight!

Stage 3: 5 months – 8 months

At this stage, your Great Dane will be almost at full growth, around 80 percent of his or her height and weight.

You may feel like you have a human child at this point—since they should be weighing around 58 kg, which is about 127 lb. They should also be as tall as 75 cm, which is around 29 inches—not much taller than where they were a few months ago in Stage 2.

Stage 4: Adult

As a fully-grown adult, your Great Dane should be around 80 cm or 31 inches tall and can weight up to 70 kg or up to 154 lb! Like we mentioned before, this is going to be a big dog—so be prepared!

What If My Great Dane Is Too Small

If this is your first time owning a Great Dane or if you’ve noticed that this particular puppy isn’t hitting those height target points when it comes to their height, then don’t be alarmed!

Speak to your veterinarian if you do have extra concern. However, when it comes to height, your Great Dane is most likely pre-determined by their parental lineage. If you do have information available about your pup’s fur-parents, this can help ease any concern you may have about how tall he or she is going to grow.

There are some specific foods you’re able to give to your dog to help them reach their full height—however, if this “full” expected height is on the shorter side, there’s generally nothing you can do!

Great Dane Genetics And Common Health Problems

With a dog this large, you can often expect for your pup to have some risks when it comes to some genetics or common health problems.

For a Great Dane, you can expect your dog to be at risk for bloat, which is actually a fatal condition where the stomach twists and can cut off blood supply. Your Great Dane is also at risk for cardiomyopathy, which is where the heart becomes unnaturally enlarged.

Your dog also might experience some sort of joint and bone disease, especially due to their large frame. This sort of risk can be minimized with supplements for the dog’s joints and bones.

A Great Dane is also at risk for thyroid issues, like hypothyroidism.

Factors That Affect Great Dane Growth 

Although the height of Great Dane is often predetermined through genetics, the growth of your Great Dane can also be affected by nutrition and exercise, which are two things that you can control.

Great Dane Growth

 Genetics

Just like any creature in the animal kingdom the genetics and family history of your Great Dane play a huge role on your dog’s height, weight, and their growth rate.

Neutering

By neutering or spaying your Great Dane, you can also expect that to affect their growth rate and overall height. Speak to your veterinarian about your choices and how it can or will affect your pup and when it will be best to neuter or spay.

Feeding

You might be thinking, if you have a big dog, the more you feed them, the more this will amp up their growth. However, Great Danes tend to grow at their own pace, no matter how much you pump them with nutritional food.

If you are trying to amp up their height or weight with higher protein percentages, all you’re going to actually be doing is increasing their risk for health complications, which we bet isn’t something you want to mess with!

For feeding recommendations, speak to your veterinarian about the quantity and frequency of feeding. With a dog breed of this size, you’ll most likely be recommended a very specific puppy food.

When it comes to feeding, as your dog grows in height, you’ll also need to pay attention to their food bowl, as it should be arranged at a height where they are not straining their neck and back to eat.

How Long Are Great Danes Pregnant?

The gestational period of a Great Dane tends to be around 2 months or anywhere from 55 – 66 days. The perfect pregnancy of a Great Dane would be 63 days. Your veterinarian should be able to help you tell if your Great Dane is pregnant, but the breed tends to show around four weeks with a firmer belly than before.

How Many Puppies Do Great Danes Have?

If you own a pregnant Great Dane, you’ll want to inform yourself before she delivers to prepare yourself for the litter! With this breed, you can expect your Great Dane to deliver around seven to eight puppies.

Knowing this information can help you prepare—emotionally, mentally, and physically for the birth of (possibly your fur-grandbabies) or potential presents for your loved ones.

What If My Great Dane Is Not The Right Weight Or Height

If you’re noticing that your Great Dane is not meeting the height or weight standards on this chart, then it might be time to speak to your dog’s vet!

Although it’s normal for your Great Dane to miss the weight by one or two pounds or inches, if there is a large overweight number or underweight number, then you’ll need to have your dog checked for any underlying issues.

A weight or height problem in their development can also be due to exercise and diet management. Check with your vet about these possibilities to see if you need to be changing anything in their lifestyle.

What Is The Life Expectancy Of A Great Dane? 

Due its extremely large size, the Great Dane can be expected to live from 6-8 years, typically (which is quite short)! Especially since the Great Dane is large in nature, this breed is going to be prone to getting bloat, hip dysplasia, and even inherited heart diseases, like dilated cardiomyopathy.

How Much Does It Cost To Own A Great Dane?

If you’re into big dogs, you’re going to also be okay with big prices. When it comes to a Great dane, you can definitely expect to pay the big bucks.

With the initial costs, you can expect to pay adoption or breeder fees, vet care, food (a lot of it!), bed, and toys, among other accessories (depending on how much you want to spend spoiling your dog). You may also be paying some extra cash for grooming, boarding, and spaying and neutering.

For the first two years with your healthy Great Dane, you’ll most likely be spending anywhere from $3,000–$10,000.
