Rottweiler Puppy Growth Chart – Male and Female

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 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!

Should I Be Worried About My Pup’s Weight?

I get many, MANY emails and submissions from Rottweiler owners who are much too concerned about their pup’s 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 a unique individual and the product of their genes. Chances are they won’t ever match the ‘average’ figures on this chart, so please don’t obsess over it, or worry that they are too small, too tall, or that their 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.

If course if you think your Rottweiler puppy is too skinny then it’s worth finding out more information to ensure they are healthy.

Rottweiler Puppy Growth Chart (Weight) – Male and Female

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.

These are just puppy weight estimates.

Full Grown Rottweiler (How Much Do Rottweilers Weigh?)

Rottweilers are well-known for how big they grow, and you may be wondering how big your dog will get in the long run. Male Rottweilers are usually taller and weigh more than female ones when fully grown.

 If you have a male dog, you can expect the animal to weigh anything between 100 lbs to 130 lbs when fully grown. Also, your dog should be about 25 to 29 inches tall at the shoulder. 

Female Rottweilers that are full grown usually weigh about 85 lbs to 105 lbs and are about 23-26 inches tall at the shoulders. Since these figures are only estimates, your dog might be slightly smaller or bigger than the figures given above.

Rottweiler Growth – a Closer Look

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.

Are Male Rottweilers Always Bigger Than Female Ones? 

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.
