Have you recently adopted a Rottweiler puppy? If so, you may be wondering how big your puppy will get and what he should weigh as he crosses important milestones during his first year!

If you’re in this situation, then you’re in luck! We’ve put together some weight and growth charts that show average weights and growth for Rottweiler puppies. And then we share important milestones your fur baby will go through on his way to becoming an adult. Let’s get started!

What is a Rottweiler?

Rottweilers are descended from an ancient dog breed called the Molossus, which was a mastiff-type dog. These dogs reached Germany with the Romans, who bred the dogs to herd and drive cattle. Experts believe the Molossus bred with native dogs, which resulted in starting completely new dog breeds, including the Rottweiler!

Rottweilers, also called Rotties, are loving, strong, large dogs. They originally came from Germany, where they were used to herd & drive call, pull carts for farmers and butchers, and more. These dogs are made for strong work, with their broad chests and muscular bodies. These dogs are built for endurance. While they may look fierce, Rotties are highly intelligent, alert, and loving with their families.

Rottweilers adopted from reputable breeders are usually calm and confident. While they are wary of strangers, these dogs will not show fear. They rather wait to see if the new person is to be accepted or not. This makes the Rottie a great watchdog. They sometimes work with the military, police and even perform customs work. However, Rottweilers also make wonderful family protectors.

These dogs have a natural instinct to protect their families and property. At times, the dogs will be fierce when protecting their loved ones. For this reason, it’s essential that Rotties are properly trained and socialized from a young age. Otherwise, these dogs can become dangerous dogs to have.

Rottweilers do best with pet parents who have a firm, gentle hand when training their fur babies. Pet parents must be dedicated to consistent training and socialization throughout the dog’s life.

Rotties usually stand between 22 to 27 inches and weigh between 85 to 130 lbs. They have a life expectancy between 8 to 11 years.

Facts About Rottweiler Growth

Rottweiler health and growth are determined by each dog’s unique genetics. That means each dog is an individual and will grow at their own rate. However, if you have a puppy, you may get an idea of how large he will grow by asking about the parents’ weight and height.

In addition, a Rottie puppy must have high quality dog food to grow up strong and healthy. In addition, these dogs need plenty of exercise. However, puppies should not be exercised too strenuously. It could hamper their growth and cause bone or joint issues as the puppy grows.

While there are some who say you can force your puppy to grow faster or larger, it’s not to your puppy’s benefit. These “experts” recommend feeding your puppy extra protein or food supplements to help them grow faster and larger. However, that can cause injuries and health issues in Rottweiler puppies.

If you ever have concerns about your Rottie puppy’s weight and growth, be sure to contact the vet. They have the knowledge and experience to help guide your puppy’s development to a happy, healthy adult dog!

Bear in mind that these weight and growth charts show only the average number of puppies at certain ages. That means some puppies may fall a little lower or be higher in weight and/or height at certain stages of growth. Most puppies will fall into these average numbers; however, each puppy is an individual and grows at their own rate.

Rottweiler Puppy Growth Stages

In this section, we’ll review the different Rottweiler puppy growth stages and milestones! Remember, these facts are based on averages. If your puppy seems to fall a little behind or be more advanced, it may only last for a short time, and soon he’ll be in the same range as other puppies of his age!

8 Weeks Old

By this time, a Rottie puppy is learning how to socialize with others. His mother will teach him the basics about being a dog and learn how to interact with his siblings. Puppies of this age also begin to learn how to interact with humans.

This is also the time many puppies are ready for their fur-ever homes. This is when the new pet parents take over the job of training and socializing their little Rottie puppy.

Three to Four Months

During this stage, Rottweiler puppies continue to learn how to socialize with humans and other animals. The puppy also starts to grow rapidly at this point. Now is a great time to enroll your fur baby into training and socializing classes meant for dogs this age.

By four months of age, your Rottie will begin to test boundaries. This is normal puppy behavior. The dogs try to determine who is the pack leader, what they can get away with, and more. This is similar to the terrible twos that some human children go through! Now is the time to enforce the rules your puppy has been learning up to now.

But remember, these dogs respond best to positive reinforcement training methods, with plenty of treats and praise.

Six to Nine Months

At this stage, it’s time to walk your fur baby outside on a regular basis. Be sure to introduce your puppy to new situations, humans, and animals as often as possible.

Now is also a great time to begin your puppy with agility training classes. This is a great way for him to learn how to behave around others (both dogs and humans) and put his energy to good use!

By the time your puppy is nine months old, he will be in his teenage period. Don’t forget that your Rottie has about 3 more months of growing ahead!

Your fur baby will have all of his adult teeth by this time and be sexually mature. He may also be shedding quite a bit. While he’s still playful, he will be starting to calm down a little bit.

12 Months

Your Rottie puppy has now developed into an adult dog! He’s finally reached his full height by this time, though he will continue to gain weight over the next year or so. Most Rottweilers continue to put on weight until they’re about three years old.

Summing It Up

So, there you have it! Now you’ll be able to tell if your Rottweiler puppy is at an average weight, too heavy, or a little behind.

Remember, any time you’re concerned about your Rottie’s growth and weight, be sure to contact the vet. They can do a checkup to make sure your puppy is developing normally. And the vet can offer recommendations on food, supplements, and more to ensure your fur baby grows up to be a happy, healthy adult Rottweiler!
