As a giant dog breed, Great Dane puppies grow at an amazing rate. Use our Great Dane growth chart so that you’ll know what to expect – and have fun tracking your Great Dane puppy’s development.
We’ll track your Great Dane’s growth using height and weight as metrics.
Of course, this is based on averages, but it will help you to see what’s normal and help you to gauge whether you are feeding your young Great Dane the right amount of food.
It can be difficult to keep up with that growth curve – especially if you’re a first-time Great Dane owner.
When Do Great Danes Stop Growing?
You’ll be proud of your Great Dane’s size and presence, but you might be wondering when that phenomenal growth curve comes to an end.
It’s a question that you may find a little hard to clarify 100 percent in our Great Dane weight chart, so if that’s what you’re hoping to find out, we’ll answer that question separately right here.
Just like young people, Great Danes usually reach their adult height before they reach their adult weight.
After the gangly late adolescence, Great Danes begin to fill out until they reach their adult weight.
So, in this instance, we have to look at Great Dane height and weight separately. When do Great Danes stop growing?
If you’re thinking about their height only, we can say that the max height is achieved at an age somewhere between one year and eighteen months.
Bulk also counts, and in that case, you’re going to see (perfectly healthy) weight gain between the ages of one and two years as your Great Dane adds muscle to their frame.
Great Dane Growth Chart
Here’s how to use our Great Dane size chart. The first step is to check the height of your great dane as measured at the shoulder (not the head).
If your puppy won’t stand still, don’t worry. You only need a moment to measure your dog’s height against your own body, and then you can measure that instead of measuring a wiggly puppy.
While your Great Dane puppy is still small enough to pick up, you’ll easily be able to weigh him at home. Weigh. Yourself first.
Then, pick up your puppy and weigh the two of you together. Subtract your weight, and you’ll have your puppy’s weight.
Once your puppy is too heavy for you to pick up, you may have to drop by your veterinarian’s offices.
They’ll have a scale that’s made specially for weighing animals of all sizes, and they probably won’t charge you anything for using it.
Check our Great Dane growth chart carefully, comparing your dog’s age to the average height and weight to see how your dog is doing.
Do remember that females are a little smaller and lighter than males – that’s why they’re listed separately.

Great Dane Puppy Development Stages
Some things can’t be reflected in numbers on a chart. Puppy development stages can’t just be explained by looking at the figures.
Next up, we explore this topic in the kind of detail you’ll need to get a clear picture of your puppy’s development and what they’ll need from you.
Birth – 2 Weeks
A Great Dane puppy of this age needs nothing from you. All he needs is his mom.
The puppy is blind, deaf, and does little more than feed and sleep. He isn’t even socializing with his littermates yet, so he isn’t ready for you either.
If you’re in the rather terrifying position of trying to raise an orphaned litter of puppies, you’ll have your work cut out for you.
Partner with your veterinarian and your family members. It will take a team to succeed.
3 Weeks – 12 Weeks
At two weeks or soon after, a miracle happens. Your puppies; eyes open and they begin to hear. They start taking their first, faltering steps.
Mom is still the most important creature in their lives, though they’ll begin playing with littermates and be ready to interact with you from the age of about 3 weeks.
After 12 weeks old, they’ll become wary about things they haven’t experienced before, so this is the time to get them used to being handled.
Begin introducing them to other people and animals too – but supervise these interactions carefully.
Weaning begins at around four weeks, and your help will be needed. The puppies can, in theory, leave their moms at eight weeks, but it’s better to wait until they’re 12 or more weeks old.
Basic obedience training can begin at eight to twelve weeks, but don’t expect too much too soon. Attention spans will be short!
4 Months – 9 Months
During this time, Great Dane puppies are likely to have gone to their forever homes.
But they’re still babies. Socialization and obedience training should be frequent and ongoing. You don’t want to end up with an uncontrollable and reactive adult Great Dane.
Start taking your puppy for short walks. Attend puppy training classes where your baby Great Dane can meet other people and animals.
Pack in all the experiences you want your dog to be able to handle calmly when it is an adult.
Milk teeth will be replaced by permanent teeth and your Great Dane puppy will have a strong urge to chew things. It’s not naughtiness. It will be up to you to gently teach them what’s OK to chew, and what isn’t.
Whatever you’re trying to teach your puppy, keep the experiences positive. If they get scared during a social interaction, take them away from it without “punishment.”
Obedience training means rewards when they get it right, but no punishment when they get it wrong.
If you have a Female Great Dane, she will enter her first heat sometime after 6 months of age. If you haven’t spayed her at 6 months, don’t allow a pregnancy yet.
Her body isn’t mature enough. You may also consider neutering males between 6 and 12 months of age.
10 Months – 18 Months
Congratulations! You now have an adolescent Great Dane. Keep up the training and socialization. Lessons learned can be forgotten if they aren’t reinforced.
Although your dog is now big and beautiful, do remember that it isn’t ready for strenuous exercise until it is about 2 years old. Too much too soon will mean a danger of arthritis and hip dysplasia.
Somewhere between 18 months and two years of age, you can expect your Great Dane to be a young adult.
As time passes, he becomes less excitable, and if you trained your dog well, the lessons should be fairly well ingrained. Nevertheless, keep practicing!
How Big Do Great Danes Get?
How Tall Is A Great Dane?
We know that Great Danes are big dogs, but just how big is “big?” A male Great Dane will be around 32 inches tall at the shoulder and can weigh up to 175 pounds.
Females will be around 30 inches tall and weigh up to 140 pounds.
Can You Predict A Great Dane Puppy’s Size?
There’s some variability between “bigger” and “Smaller” Great Danes. Can you predict your puppy’s size?
That’s a bit difficult. You can look at the parents, but they also carry the genes of your puppy’s grandparents and great grandparents. So, although big parents usually mean a big puppy, that may not always be the case.
Your puppy weight chart might also indicate that your pup outstrips average height and weight. If so, it might be a big adult – or its growth might slack off later.
Remember that weight isn’t everything. An overweight puppy is just fat – not necessarily a “bigger” dog.
Although we often look at the paws, that’s not sure-fire either – a DNA test might give you a more precise answer if you really want to forecast your Great Dane’s size.
Will Neutering/Spaying My Great Dane Affect His Growth?
Of course, you’d like your Great Dane to reach its full potential. Will spaying or neutering or spaying prevent that from happening?
The good news is that it won’t. Research has shown that neutering or spaying don’t affect a dog’s physical development other than it’s hormonal and sexual characteristics.
So, if you don’t want the hassle of caring for females in heat or male dogs eager to go courting, go ahead and spay or neuter.
Spaying and neutering does seem to reduce the chance of certain cancers, so it could be a good thing for the health of your dog.
At the same time, timing is everything. Never neuter or spay a dog that is younger than 6 months old. Chat to your veterinarian about the best time for spaying or neutering for your specific pet.
So what factors do affect a Great Dane’s growth? Let’s look at that next.
Factors That Affect Great Dane Growth
Genetics & Gender
Female Great Danes rarely get as big as males do. On average, they’re 2 inches shorter and considerably more lightly built.
Genetic variability also enters the picture. As previously mentioned, big parents usually have bigger offspring – with possible variations based on the puppy’s parents’ ancestry.
No young living creature can reach its genetic potential without proper nutrition. However, it’s a delicate balance.
When puppies are allowed to be overweight, there’s a great chance of hip dysplasia later on. But an underweight puppy won’t grow to the full size it’s capable of reaching.
And, with your puppy growing by leaps and bounds, you’ll barely have the balance right when it will be time to adjust how much you feed them.
Of course, you needn’t reinvent the wheel. Others have gone before you’ll be able to get broad recommendations that worked for others.
Physical Activity And Health
Physical activity is required for your Great Dane puppy to build strong muscles and “bulk up.”
Health issues, like nutrition, can reduce your puppy’s potential to reach the size its genes allow for.
You’ll be keeping an eye on your precious Great Dane puppy’s health. If it seems “off color” or unwell get it checked out as soon as possible. Like children, puppies can go from being perfectly well to desperately ill pretty quickly.
Vaccinations are a must – don’t try to second-guess the dreadful doggie diseases that vaccination can eliminate.
How Much To Feed A Growing Great Dane Puppy?
A good commercial dog food should specify how much should be fed based on the weight of your puppy.
Before the age of 4 months, you should split the daily food allowance into three servings, and from the age of 4 months, you can transition to two servings.
Supposing that you’re using a good quality puppy food, your Great Dane puppy will need:
- Four to six cups of kibble per day from the age of four months
- Five to eight cups a day from 5 months old to 6 months
- Six to nine cups from the age of seven to eight months
- And 7 to 10 cups for the 9th and 10th month.
However, this is a very broad estimate.
What To Do If My Great Dane Isn’t The Right Weight?
You definitely don’t want an over or underweight Great Dane. But before you decrease or increase feeding, take a look at your dog.
If you check out the top view, you should see a waistline. If you don’t, your dog needs better diet control and more exercise.
Now, check out the rib cage area. You should not see ribs protruding through the skin, but if you run your hand over the ribcage, you should be able to feel the ribs under the skin.
Do Great Danes Experience Growing Pains?
Great Danes can experience “growing pains” during growth spurts. This condition is known as panosteitis and it involves some very painful inflammation.
Your dog will be very uncomfortable and your veterinarian can help with treatment.
It’s also possible that something else could be the matter. Don’t take it lightly if your puppy is in pain. But you wouldn’t, would you?
Great Dane Genetics And Common Health Problems
Hip dysplasia can develop over time,so getting a puppy who has been screened for hip dysplasia is not a guarantee that it won’t occur.
Nevertheless, it does mean a lower chance, and ethical breeders are usually willing to provide the necessary reports.
Like other large breeds, you need to be careful of bloat: a condition that can be fatal.
To reduce the chances of this happening, don’t feed your adult Great Dane one large meal a day – split it into at least two smaller meals.
You also shouldn’t feed your dog before exercise or feed him from a bowl that’s placed on a table or chair.
Bloat is the leading cause of death among Great Danes, so keep an eye on your dog.If you suspect bloat, get to a veterinarian as soon as possible. It’s an emergency!
Symptoms of bloat include a swollen tummy, the dog retching as if he wants to throw up, extra drooling, and restlessness since he can’t get comfortable.
Heart and thyroid issues can also be inherited. The latter needn’t be a huge problem for your Great Dane – as long as it is diagnosed and treated.
Be sure to take your pet for checkups at least once a year and visit your veterinarian if you notice anything odd about your Great Dane.
English Mastiff Vs Great Dane Size
It’s a close call between the size of Great Danes, Irish Wolfhounds, and English Mastiffs. The Great Dane generally wins on height, but a smaller Great Dane could be smaller than a large English Mastiff.
On average, however, English Mastiffs are fractionally shorter than Great Danes which are widely accepted as the tallest dog breed out there. However, Mastiffs are heavier, so it’s a point that could be argued.
The Great Dane is a truly spectacular-looking dog with a heart of gold. It’s unfortunate that big dogs don’t live very long, but the sheer privilege of having such a wonderful companion offsets that disadvantage.
With lots of love and the right care, you can maximize your chances of keeping your dog healthy and happy for as long as possible.
Since you’re doing your research and looking up the Great Dane height and weight chart, you clearly intend to be the best Great Dane parent ever.
We hope you’ll soon be turning heads in the local doggie park as you and your giant canine companion strut your stuff!
