Rottweiler Growth Chart: What to Expect

Rottweiler Development

Birth – 2 weeks

During a Rottweiler’s first two weeks, you can expect a lot of eating and sleeping—just like with human babies. They don’t generate their own body heat, therefore, rely on their mom to keep them warm. A Rottweiler weighs between 12 oz. and 3.7 pounds.

3 weeks – 12 weeks

During this stage, the puppy starts to open their eyes and their ears begin to function well. They develop their milk teeth at three weeks and can then consume solid foods. They also start wagging their tails and begin to socialize properly with the litter.

At these stages, the puppy is encouraged to interact with humans to avoid social problems. Their weight at this stage is between 3.7 pounds to 38 pounds.

4 Months – 6 months

This is a teenage stage where the puppy starts to know what they can do or cannot. Therefore, with good training, they will create good habits and not run wild.

Depending on the regimen, training can take up to 20 minutes per day. It will take almost 7 days for your puppy to comply and remember.

At this age, Rottweiler weighs 43 pounds to 70 pounds.

7 months – 9 months

Rottweiler Weight Chart

This will continue as he enters his teenage years. Closer to the end of this time is when you can expect your Rottweiler to begin changing his coat and entering sexual maturity. 

10 months – 12 months

The unique structure of the Rottweiler causes them to still gain weight, even though 12 months have passed. This period is just before growth plates begin to harden.

There are some Rottweilers that continue to develop until they reach 3 years old. This is because of their broader chests and muscles.


At this stage, you need to put more effort into training your puppy and getting them socialized better (especially with other dogs).

A Rottweiler will be matured at the ages of 2 to 3 years. As an adult, Rottweiler weighs between 105 pounds and 120 pounds.

Neutering or spaying your Rottweiler at an early age comes with a myriad of risks. There are a few reasons why you should wait until your Rottweiler is at least 2 years of age, which is the time that they usually stop growing on average.

The reason for this is that the sex hormones that are coursing through your Rottweiler’s system are associated with growth and development. This is why spaying or neutering can affect the development of your Rottweiler.

This wouldn’t be a problem within itself, but the maturity of your Rottweiler may affect the growth plates, leading to serious complications related to walking and running. 

However, spaying and neutering have certain advantages when done at the proper age such as the regulation of the pet population, prevention of certain diseases, and saving money.

Alternatively, spaying or neutering may cause your Rottweiler to be agitated, and there is also the risk associated with any type of surgery.

Rottweiler Weight BCS

The Body Condition Score (BCS) is simply the pet version of what humans use as BMI. It calculates body fat in pets. However, it can be a bit more complicated because there are a variety of dog breeds in many shapes and sizes.

BCS calculations are important because they help to standardize the weight of an animal and can be used as the foundation when it comes to recommending diet and exercise for your Rottweiler.

BCS calculations take place by looking at your dog’s silhouettes from the side and above, paying particular attention to the spine, ribs, waist, hip bones, muscle mass, abdomen, and overall fat covering.

You should be able to observe your dog’s waistline from above when they are at a healthy weight. When you observe them from the side, their abdomen should be tucked behind the rib cage.

It is also important to use your hands and feel because some dogs have thick and long fur which prevents objective observation. You should feel a thin layer of fat along the rib cage in a healthy dog.
