When is a Doberman Full Grown?

Dobermans are a big breed of dog, and they can grow quite large. Many people want to know when their Doberman will reach full maturity. This can depend on many factors, including the individual dog’s genetics and health. Most Dobermans will reach their full size by about two years old. However, some may take a little longer, while others may reach maturity sooner. So how do you know when your Doberman is fully grown? Every dog is different, but there are some things to watch out for that can help you determine whether your Doberman is done growing. Keep reading to learn more!

Two Major Growth Phases for a Doberman

A Doberman will go through two major growth phases in its lifetime.

  1. The first phase occurs between 0 and 12 months when the Doberman is a puppy. Puppies grow very quickly during this time, and their bones and muscles are still developing. As a result, they need a diet that is high in calories and nutrients to support their growth. 
  2. The second growth phase occurs between 12 and 24 months when the Doberman is young. The Doberman’s growth rate begins to slow down during this time, but it is still putting on weight and muscle. It is important to switch to a maintenance diet to avoid overfeeding at this stage. Understanding these two growth phases can ensure that your Doberman stays healthy and grows to its full potential.

However, it is important to note that every dog is different, and some may reach their full size sooner or later than others. A few other factors can affect a Doberman’s growth, including diet and health. So, while most Dobermans will be fully grown by two years old, there is a chance that your dog may take a little longer or reach maturity sooner.

Doberman Growth Stage

  • Birth: The Doberman is born with eyes shut and ears tightly creased. Doberman weights between 10-20 oz.
  • 3 Days to 6 Weeks: The Doberman’s eyes will open at three days old. Around the same time, they’ll start to teeth. They are weaned from their mother’s milk at six weeks old and begin eating solid food. Weights around 8-12lbs.
  • 6 Weeks to 7 Months: From six weeks to seven months old, the Doberman undergoes a rapid growth spurt. They’ll grow from an average weight of 30 pounds at six weeks to around 70 pounds by seven months old. 
  • 7 Months- 1 Year: The Doberman reaches its full adult size from seven months to one year old. However, it is not considered fully mature until around two years old. 
  • 1 Year- 7 Years: The first year is considered the puppy stage where they learn and grow. By the second year, they are adolescents. Around three years old, they reach full mental maturity. For the next four years or so, they are considered adults. After seven years, they are considered seniors.

As you can see, a Doberman will go through several growth stages in its lifetime. It is important to understand these stages to provide your dog with the proper care and nutrition. Now, we will look in detail at each stage by type so that you know what to expect and how to care for your Doberman at each stage of life.

Nursing and Weaning

  • The Doberman puppy’s eyes are shut for the first three days of life, and its ears are tightly creased. They weigh between 10-20 ounces and are completely dependent on their mother for food. 
  • After three days, the Doberman’s eyes will start to open. Around the same time, they’ll start to teeth. 
  • The Doberman is weaned from its mother’s milk at six weeks old and begins eating solid food. However, it is important to note that the Doberman’s diet should still consist mostly of puppy food during this time. 
  • As the Doberman starts to eat solid food, you may notice that it has a lot of energy and is always on the go. This is completely normal and is just a result of the Doberman’s high metabolism.

Cropping of Ears and Tails

One of the most distinctive features of the Doberman is its cropped ears and docked tail. This procedure is done when the Doberman is between two and four months old in most cases. 

The cropping of ears and tails is a cosmetic procedure that is purely optional. However, many people choose to do it as it is thought to give the Doberman a more intimidating appearance. 

If you decide to have your Doberman’s ears and tail cropped, it is important to find a reputable vet who has experience with the procedure. 

The cost of ear cropping and tail docking can vary depending on the vet and your region. You can expect to pay between $150 and $600 for both procedures.


Around the same time that the Doberman is weaned from its mother’s milk, it will start to teeth. This process usually starts at around twelve weeks old and can last until the Doberman is three months old. They will lose their baby teeth and get their adult teeth. It’s common for them to swallow their baby teeth.

You may notice that your Doberman is chewing on many things during this time. This is normal behavior and is just the Doberman’s way of dealing with teething discomfort. 

To help your Doberman through this process, you can give them chew toys or rawhide bones to gnaw on. This will help relieve some of the discomforts and prevent your Doberman from chewing on things that it shouldn’t. 

If you notice that your Doberman has trouble teething, you can talk to your vet about giving them pain relief medication.

  • During the first few weeks of life, the Doberman puppy grows rapidly. They gain around 10-20 ounces each week and double their birth weight within two weeks. 
  • The Doberman puppy is usually around 8-12 pounds by six weeks old. This is when they are weaned from their mother’s milk and eat solid food. 
  • Doberman’s growth will slow down from six weeks to six months. They will gain around 5-10 pounds each month. 
  • The Doberman will reach its full adult height at around twelve months old. However, they will continue filling out and adding muscle mass until they are around 18 months old. 
  • The Doberman will reach full adult weight by around 18-24 months old. However, it is important to note that males generally weigh more than females. 
  • Males usually weigh between 75 and 100 pounds, while females weigh between 60 and 90 pounds. 

Doberman Height

  • The height of a Doberman can vary depending on its sex and breed. In general, male Dobermans are taller than female Dobermans.
  • Males usually grow to be around 26-28 inches tall at the withers, while females grow 24-26 inches tall. However, there is some variation between different breeds of Doberman.

Behavior Changes

Doberman Pinschers are well-known for their loyalty and intelligence, but they can also be headstrong and stubborn. Fortunately, with the right training, they can be excellent companions.

Here are some things to keep in mind when training a Doberman:

  • At 12 weeks old, puppies are just starting to learn about the world around them. This is an ideal time to start socialization training, which will help your dog become comfortable with new people and situations.
  • By six months old, most Dobermans are near the end of their teething or puppy nipping and are ready to start schooling. However, they are still considered puppies at this stage and may behave accordingly. Be patient and firm with your training, and don’t give in to begging or other bad behavior.
  • At one year old, your Doberman is starting to reach adulthood. This is a good time to continue socialization training and begin obedience training. Teaching your dog basic commands such as “sit” and “stay” will help you establish yourself as the alpha leader of the pack.
  • By two years old, your Doberman should be fully grown and well-trained. If you’ve been consistent with their obedience training, they should be able to follow commands and behave appropriately in most situations. However, they may still have moments of puppy-like behavior, so be patient and firm.

A Doberman can be a loyal and loving companion with the proper training for years to come.
