Rottweiler Size By Age Predictions

Rottweiler is a medium to large sized breed. Although they can look intimidating to some, they are fun-loving goofballs with a confident mannerism, and affectionate nature. Rottweilers are completely devoted to their families and can become protective if needed. They’re blessed with high intelligence levels, and respond well to training. 

With proper training and early socialization, you can be sure that your Rottweiler pup will enjoy cuddling and maybe even try to fit onto your lap. Even though Rottweilers can be great guard dogs, they should be able to spend plenty of time with their humans. 

So how big do Rottweilers get? By the AKC breed standards, Rottweilers can weigh anywhere between 80 to 135 pounds, and stand at 22 to 27 inches tall at the shoulder. If we’d like to estimate a Rottweiler’s full size when grown up, the easiest way to do that is to look at the parent pups.

Of course, this is not always possible when adopting a puppy from a shelter. However, if you opt for adopting a furry family member from a breeder, they will be able to shed some light onto the size of the parent pups, and the size of puppies in each litter. 

Additionally, Rottweilers are at a risk of hip dysplasia and joint problems. Feeding your Rottweiler puppy a high-quality large breed puppy formula is a good way to support their proper growth and development, and reduce the risk of developing joint problems. 

Furthermore, for a puppy to grow into a healthy, full-grown adult dog, it’s important they get the right amount of food. Make sure to check out our article on how much your dog should eat. There you’ll also find our dog food calculator, to save you the work!

Are There Different Sizes Of Rottweiler?

When it comes to predicting a Rottweiler puppy’s full-grown size, their gender can make quite a difference in the outcome. Usually, male Rottweilers tend to be larger than females in both height and weight.

Let’s have a look at an average Rottweiler size chart for males and females:

Male RottweilerFemale Rottweiler
Weight95-135 pounds80-100 pounds
Height24-27 inches22-25 inches
When Full-Grown?18-24 months18-24 months

*A dog’s height is measured from their withers also known as shoulder blades.

As we can see from the Rottweiler size chart above, a full-grown male Rottweiler can weigh around 95 to 135 pounds, and stand at 24 to 27 inches tall at the shoulder. Female Rottweilers carry a bit less weight and typically stay in the range of 80 to 100 pounds. Female Rottweiler’s height ranges from 22 to 25 inches at the shoulder.

There’s also a rumor about the Mini Rottweiler size. However, there’s no such thing as a purebred Mini Rottweiler. The smaller Rottweiler pup can be either a runt or a puppy who is a result of two Rottweiler runts or have the dwarfism gene. Either of the options usually indicates a high risk of health problems. Therefore, responsible breeders won’t breed smaller puppies just for the sake of the looks. 

In addition, some ‘Mini Rottweilers’ or Pocket Rotties are in fact a mix of a Rottweiler and another, smaller breed. Often these mixes include a Rottweiler parent, and another parent breed like Beagle or Poodle. The Mini Rottweiler’s full size can fit anywhere between 30 to 60 pounds in weight. 

Rottweiler Size Charts & Growth Patterns

Like most other dog breeds, Rottweilers will go through the most rapid growth stages in the first 6 months of their life. From there on, their growth will gradually slow down, and they might finish growing around the time they’re 18 to 24 months old. Typically, smaller Rottweilers will reach their full-grown size sooner than larger Rottweilers. 

Additionally, this is why it’s particularly important that your Rottweiler puppy gets the correct nourishment he needs to grow that adorable little body into a healthy adult one. Check out these guides on best dog food for puppies here.

As we can see from the chart, Rottweilers usually reach most of their adult height by the time they’re 9 months old. However, you can expect your pup to reach their adult weight around the time they’re 2 years old. Moreover, some Rottweilers can take up to 3 years to fill out their chest and finish growing!

Is Rottweiler A Large Breed?

Rottweiler is a medium to large sized breed. However, they are more often referred to as a large breed. 

When choosing the best food for your Rottweiler puppy, we recommend you look for puppy formulas specially designed for large breed dogs. This will promote proper growth and development in puppyhood, and reduce the risk of health risks later on in life. 

How Big Is A Full-Grown Rottweiler?

Rottweiler is a large breed dog with the largest pups weighing up to 135 pounds as adults! Usually, male Rottweilers are larger than females. A male Rottweiler can weigh around 95 to 135 pounds, and stand at 24 to 27 inches tall at the shoulder. Female Rottweilers usually weigh around 80 to 100 pounds, and stand at 22 to 25 inches tall at the shoulder.

You can calculate their potential adult weight at 23 weeks by taking what they weigh at that age and multiplying it by two.

A different formula you could use is:

  1. Growth = current weight / current age in weeks
  2. Adult weight = Growth x 52 (number of weeks in one year)

So, for example, if your 12-week old pup weighs 18 pounds. You simply divide the current weight by their age in weeks and multiply the result with 52:

18/ 12 = 1.5
1.5 x 52= 78 pounds

78 pounds would be the expected weight of your adult-sized Rottweiler.

Although Rottweilers can look like a lot of work, they are actually very loving and devoted companions who will be loyal to you until the end of time.
