Rottweiler Puppy Growth Chart

If you’re wondering if your Rottweiler pup is too small/too big or ‘just right’, this Rottweiler Puppy Growth Chart has the answers!

Rottweiler puppies are adorable little ‘butterballs’, but like any other breed they’re all individuals and can vary quite a bit in size, structure and personality. Although there’s no ‘one-size-fits-all’ formula for judging Rottweiler weight or growth, there are formulas that can help you reach some approximated puppy weight estimates.

You can use those as guidelines for evaluating your own pups’ development, and to get an idea as to whether or not he’s above (or below) the ‘average’….. but please remember there is no such thing as an average puppy.

Each and every one of them is unique and precious, how much they weigh is only important if there’s a health concern!


Puppy Weight Estimates & Average Puppy Weights

Rottweilers are big, powerful dogs, and many new Rottweiler puppy owners worry, fret, or even obsess, about their baby’s growth and weight gain……. usually needlessly.

This is when a having a Rottweiler puppy weight chart can really come in handy!

If you’re the proud owner of a new Rottie pup, it’s important to bear in mind that this is a large, slow-growing breed, and your little one won’t be considered ‘mature’ or fully grown until he (or she) is at least 18 months to 2 years old.

Some of these big dogs, especially the males, may not gain their full adult weight until they are 3 years old or even older.

It’s also very important to realize that there is NO HURRY for your pup to gain weight – in fact trying to make your pup ‘bulk up’ or trying to accelerate his growth often results in health issues such as bone/joint problems or even heart failure or disease.

Please remember that any puppy weight estimates are just that – ESTIMATES! And there is no such thing as an ‘average’ puppy (at least I’ve never met one), so use common sense and use the figures in the Rottweiler puppy growth chart below as a guideline – not the gospel!



I get many, MANY emails and submissions from Rottweiler owners who are much too concerned (read ‘worried’) about their pups weight, head size, height and so on.

They seem to get quite obsessed by how big their puppy, or dog, is and often that overshadows everything else. I always feel sad, and a bit frustrated, when I see this happening because a Rottweiler is so much more than just his size and/or outward appearance.

Rotties are absolutely awesome dogs and they have huge hearts, amazing personalities and are courageous, loving, goofy and totally loyal to their humans. These aspects of the breed should never be seen as secondary in importance to their size or ‘look’.

I think the hype surrounding Rottweilers is somewhat to blame for this obsession, but no one should ever buy a puppy of any breed solely for their ‘reputation’ or based on looks.

The Rottie you own is an unique individual, and the product of his genes. Chances are he won’t ever match the ‘average’ figures on this chart, so please don’t obsess over it, or worry that he’s too small, too tall or that his head isn’t big enough!

Just love him… and remember that this Rottweiler puppy growth chart is supposed to help you, not stress you out 🙂


Your Rottweiler Puppy Growth Chart (Weight)

At any given age there’s quite a wide range of possible weights, and your Rottweiler puppy could be on the lower end, the higher end, right in the middle, or even above or below the given figures.

Also realize they are not ‘sex specific’ and there can be a significant difference between the weight of a female and male pup at the same age. Females will generally be on the lighter end of the scale, males towards the heavier end. But not always, there are a lot of variables!

These are just puppy weight estimates.

Your Puppys’ Age

Average Puppy Weights

Birth 12 oz – 1.3 lbs
1 week 1.8 lbs – 2.6 lbs
2 weeks 2.9 lbs – 3.7lbs
3 weeks 3.7 lbs – 4.9 lbs
4 weeks 4.9 lbs – 6.5 lbs
5 weeks 6.5 lbs – 8.6 lbs
6 weeks 8.8 lbs – 11.0 lbs
7 weeks 10.2 lbs – 13.5 lbs
8 weeks 12.0 lbs – 15.8 lbs
3 months 33 lbs – 38 lbs
4 months 43 lbs – 50 lbs
5 months 53 lbs – 60 lbs
6 months 63 lbs – 70 lbs
8 months 75 lbs – 85 lbs
10 months 85 lbs – 95 lbs
12 months 90 lbs – 105 lbs
24 months 105 lbs – 120 lbs

If you’re concerned and want to keep a close eye on weight, get yourself a scale. They are relatively cheap and you can use it to make sure your dog maintains their weight throughout their life.

Rottweiler Puppy Growth Chart (Height)

Average puppy heights are also subject to a fair amount of variation, so these are AVERAGES only. Most puppies will not be average!

Female Rottweiler puppies usually weigh consistently less than male puppies but when it comes to height up until about four months the girls may be slightly taller than the boys.

Your Puppys’ Age

Average Puppy Heights

2 months 13 inches – 13.5 inches
3 months 18.5 inches – 19 inches
4 months 19.5 inches – 20 inches
5 months 21.5 inches – 22 inches
6 months 23 inches – 23.5 inches
8 months 24.5 inches – 25.5 inches
10 months 25 inches – 26 inches
12 months 25 inches – 26.5 inches
24 months 25 inches – 26.5 inches


Rottweiler Growth

If you want to know how big your precious little puppy will be as an adult, you’ll need to do more than consult the chart above!

There are all sorts of things that factor into the eventual size/weight/height of your dog.

These include his/her bloodlines (genetic component), the size of his parents, metabolic rate, diet, activity level and more.

If we are talking averages here, then you can generally expect your pup to ‘top out’ somewhere between the weight of his parents.

Male pups tend to be closer to the sires’ adult weight, and females to the Dams’ adult weight, but again there’s nothing written in stone, and every pup is different.

Although males usually tend to be bigger and heavier than females, it’s perfectly possible for a female from one set of parents to be bigger and heavier than a male from a different set of parents. Bloodlines and genetics play a big role.

The rottweiler puppy growth chart above shows a range of average puppy weights.


Sometimes puppy owners are so anxious to see their pup grow, that they are tempted to overfeed them in an effort to ‘speed things up’.

This is a very BAD IDEA, and can cause all sorts of long-term health problems (including damage to the bones/joints/ligaments, heart disease and other chronic illnesses)

If you compare a male and a female pup from the same litter, the male is likely to be towards the higher end of those figures, and the female towards the lower end.

But comparing pups from different litters/parents, could produce totally different results.

If you want to keep your Rottweiler pup healthy, it’s important to be patient and allow him to grow and develop at his own pace!

Remember – Rotties grow and mature slowly, and the eventual height/weight of your pup is determined mostly by genetics.

But, making sure that he eats a premium puppy food, in the right quantities, will help him reach his maximum potential, and keep him in tip-top shape.


Estimating Your Rottweiler Puppy’s Growth & Weight Gain

Do you want to know if your puppy is gaining weight at a ‘normal’ rate?

Or are you interested in learning additional methods for calculating puppy weight estimates?

Having difficulty converting your pup’s weight?

If so, there are a couple of other handy tips that you can use in addition to the Rottweiler puppy growth chart above.

Again, I must stress that these are ways of estimating rottweiler growth, and are based on average puppy weights.

So don’t expect them to be totally accurate, or get worried if your pup doesn’t seem to want to be ‘average’!

First, here are some interesting tid-bits about Rottweiler growth and development that you may not know….

  • Most rapid growth occurs between birth and 8 months of age
  • Your pup will gain his full height before he reaches his full weight
  • Most Rotties don’t mature until 18 months – 2 years old
  • Some pups (more often males) don’t finish growing until they’re 3 years old or more
  • During adolescence your pup might (probably will!) look awkward, even scrawny!

Here are some additional handy ‘rottweiler puppy growth chart tips’ to help you figure out how much weight your Rottie pup should gain as he grows.

  • ‘Average’ pups may gain between 4 and 5 oz per day for the first 6 months
  • An average weight gain of 10lbs per month up until 8 or 9 months of age is common
  • You can estimate the adult weight of your pup by doubling his weight at 4 months, and adding approx. 10lbs
  • By 6 months your pup may have reached almost two-thirds (66%) of his adult weight
  • At the same age he will likely have gained 75% of his adult height

This inequality in his percentage gain of weight v height accounts for the awkward, gangly ‘puppy uglies’ stage that many adolescent dogs go through!


Things Worth Remembering……

  • There is no such thing as an ‘average’ puppy, and these puppy weight estimates are just ‘ball park’ figures.
  • All puppies are different, and a lot depends on genetics and bloodlines.
  • Even healthy pups within the same litter can vary greatly in size/weight.
  • It’s important not to rush your puppy into gaining weight, or overfeed him. This can lead to health problems.

And finally……..

Enjoy your Rottweiler puppy while he’s small – believe me, he won’t stay that way for too long!

  1. Thank you i found it very informative and helpfull. I have 4 gorgeous registered rottweilers and they bring me more joy than life itself. A truly unique breed and i hope people take the time to watch them flourish with love patience plenty of stimulation and training

  2. I’m concerned about my rottie. He is 2 years old and just slightly bigger than my pit bull. At last vet visit he only weighed 77 lbs. I paid $1000 for him and he is papered. Was told he is a full blood German rottie. I’m felling a little screwed (sorry).

    • You cannot get a Rottie puppy and assume their growth potential. Whatever his size, they are the best breed on the planet. Consider if he is pure German, and you should have his pedigree, contacting a breeder that is interested in down-sizing, and maybe using him as a sire. Watch the Pit; we have a Frenchie that is hell-bent on proving dominance with our male rottie pup.

    • You should take into consideration that German rotties are smaller and more compact than their American variation. His smaller size does not necessarily mean he’s not pure bred.

    • I paid 2 grand for my female German rottweiler pup at 9 weeks old and she is 9 months old and weighs 66lbs..I’m guessing she will be between 90 – 100 lbs full grown ..her mother was 110 & her father 130 I’m hoping she’s going to be pretty big

  3. I have a 5 month old female Rottweiler, she is starting to yelp when she gets up from a laying position but not all the time. Could it be from her growing so fast, she’s very active, runs, plays and jumps. Her gait is good. Just started to bothering her about a week ago. She’s not over weight. She’s very active all the time. Could she be growing to fast and should I be worried about her? Could she play too much sand hard to get her hips hurting. She loves to run and jump when she goes outside.

    • Could be bad hips or too much protein in her diet. Yes too much protein is just as bad as none at all. I work with an owner that feeds his Shepard vertex for the added protein. His dog would yelp when it stood up, and have pains all the time. He lowered the amount of protein in the puppy’s diet and everything went back to normal. Still consult a vet is my recommendation, just added insight on what it could be.

    • Dear God! Please have her checked out for dysplacia. My husband had a female that did the same thing. He replaced her hips. A year at the vet healing and $20,000 later, she passed at four. Always buy an OFA certified pup!!! It’ll save you heartache and pay off in the long run.

  4. I agree with Mr. Ladd you may have gotten a mix 3 like you said for good bloodlines and guarantee temperament and hits you gonna pay at least 2027 $100 I just bought my baby girl and she cost me 1800

    • i’ve had rotties all my life, as companions only- no breeding or showing, and you are right. The lowest price you’ll ever pay will be around 1800, and that’s for a companion pup. That also usually means a spay/neuter contract(though not always), and no 1st, 2nd, 3rd pick of the litter choice. My current boy was bought as a comapanion animal with no spay/neuter contract, and the breeder gave me a 600$ discount for signing an optional spay/neuter contract to be enforced no sooner than 24 month old and no later than 30. I take it as a very good sign that she was far more concerned about the well-being of her pups than the cash they brought in.

  5. Hi, I paid top money for my pup he is gorgeous but I am a little worried about his size. He looks small to me at 14 wks he is 25 lbs people ask me if he is 8 wks old…..I was also told that not to worry he will grow. He has massive feet. We don’t want him growing too fast just a bit worried since we want to show him

    • Just like this page says don’t worry about their weight too much when they are puppies. Just feed them healthy and watch. My Rottweiler is small for his age also but I continue to feed him at a steady pace 4% of his current weight. He weights about 80lbs now at 19months and last check up with the vey says all is well. That’s with an echo, xrays, and full labs. He’s growing to his full weight slowly but surely

  6. I have a 10-month old female Rottweiler puppy and she weighs 102 lbs. Based on your chart, at her age, she should only weigh 85-95 lbs. And since she’s more than that, is there a need for her to be on a diet or is it just fine? Please advice me on this, thank you in advance.

    • My advice would be to take her to the vet and see if she’s overweight or just a big girl. With their straight legs and large bodies, rottweilers need to maintain a lean physique to avoin putting stress on their hips and joints.

    • You need to moderate the ammount she eats. A rottweiler needs to maintain a lean physique, or she will have hip and joint pr-oblems later on.

  7. I have a 6 month female Rottweiler. She is verry nice aggressive, loyal, obedient. She js now 16kg. Is it good her height is 19 inch right now. TELL some review about her. If anyone can assist me something plz tell..

  8. I have a male rotti he is 18.5” tall weights 43lbs I feed him blue wilderness I feed him the 4 cups a day like it says on the bag, he seems like he is still really hungry I paid 700 for him I saw both parents and the mom was a big girl but the dad was only 18 months and a 100lbs and looked small should I be concerned he isn’t full bred or is his size due to under feeding?

  9. We have a female rotti she is 10 months old, she comes from a great blood line, we feed her science diet, I give her 4 cups per day and I feed her from the table too, the last weight we got on her was about a week ago and they weighed her at 74 lbs. she is very much a puppy she is potty train well but she destroys something if we leave her home alone, she has chewed up 2 wicker baskets and she chewed a hole in the sheet rock !!! HELP

  10. What are some good dry food for Rottweilers? I have a 4 month old and I’m currently giving him Simply Nourish puppy food but I feel like it’s not good enough he likes it very well and I haven’t weighed him but if you have any recommendations for great food please respond

    • It can be pretty pricey but i use wellness large breed puppy. Its about 75 dollars for a 30 pound bag but my 11 month old male is already 110 pounds of muscle and 27 inches tall. I tried a couple other foods before including Taste of the wild and Blue wilderness both of which were horrible on his stomache.

  12. I’m 70 and have had n rotties since 20’s. My suggestion is investigate Bil-Jac food. I have fed my dogs it exclusively. I think,after much research, it is the very best food available bar none and regardless of price. I hope for the dogs sake you will research this yourself.

  13. I have a rott/lab mix she is 9 weeks old and I was just wondering what should she weigh. Her dad weighs 150lbs and her mom is a solid 80lbs

  14. My rotti had 13 pups, 9 female / 4 male, but only 3 survived, this was her first litter. I sold two of them. The one I kept is four months old, (51 lbs). His parents are (105 lbs) & (120 lbs), female is the biggest, but I think he’s going to be bigger than his parents. His moms parents are approximately 150 lbs each.
