When Do German Shepherds Stop Growing?

When it comes to German Shepherd dogs, one question that is prevalent among owners of this wonderful pooch is when their dog will stop growing and be considered an adult.

In regards to when German Shepherds stop growing? Most times, a German Shepherd dog’s growth starts slowing down from when the pooch is one-year-old, and German Shepherds typically stop growing completely between the ages of two to three years.

Three years may seem like a lengthy period for a German Shepherd dog (GSD) to be fully considered an adult, but this is what is obtainable with most large dog breeds. To ensure your German Shepherd grows to become the best possible version of itself, appropriate feeding is essential during this developmental phase. And we’ve included tips on how to properly feed your GSD puppy, along with what is considered healthy weight for this dog at different stages of its life. Before we go into all this though, let’s take a look at the phases of a German Shepherd dog’s growth.

At What Age Is A German Shepherd Fully Grown?

Like most large dog breeds, German Shepherds are not regarded as fully mature until they are about 2 to 2.5 years old, with some even taking up to 3 years to mature! And no matter how big they grow in that period, German Shepherd dogs are typically considered to be puppies till they attain full maturity.

The stages of development and maturity in a German Shepherd dog, from the point of birth right up to when the pooch is a full grown adult, can be classified as follows:

The Neonatal Stage (0 To 2 weeks)

The neonatal stage marks the period preceding a German Shepherd puppy’s birth, and it typically lasts for two weeks.

GSD puppies are usually born blind and they are totally helpless during the neonatal stage. During this stage, the puppies spend most of their time eating and sleeping.

The Transitional Stage (2 To 4 weeks)

At this stage, the German Shepherd puppies have opened their eyes, and are aware of happenings in their surroundings. It is also around this time that the puppies will begin to walk, although their movements may still be a bit wobbly.

The Socialization Stage (3 Weeks To 6 Months)

The socialization stage of a GSD puppy’s life typically begins when the pooch can walk on its own without assistance, and it usually spans for more than five months.

During this stage, it is important to introduce GSD puppies to new people, animals and environments, as this will play a major impact in shaping the dogs’ future behaviour.

You can begin feeding soft dog food to the puppy during this period, and it is recommended that you housebreak the pooch when it is 8 weeks old.

The Juvenile Period (3 To 6 Months)

The juvenile period precedes the socialization period of a GSD puppy, and it is at this stage that the dogs begin to develop the urge to investigate their surroundings more.

It is also recommended that you begin training your GSD puppy during this juvenile stage. And by incorporating positive reinforcement and keeping training sessions short, you will get the best out of your pooch.

It is also worth noting that the teething process in German Shepherd puppies typically happens during the juvenile period. Also, by the end of this period, GSD puppies will have attained, at least, 70% of their expected adult height and weight.

The Adolescent Stage (6 Months To 2 Years)

The adolescent stage is undoubtedly the longest period of a German Shepherd’s road to full maturity. And this is typically the time when GSD puppies attain sexual maturity, with females going into heat and the males starting to display sexual behavior.

The German Shepherd also attains the peak of its physical development during the adolescent stage, but there usually remains aspects of the dog’s mental capacity to be worked on.

The Maturity Stage (2 To 2.5 Years)

The maturity stage sets in when a German Shepherd is considered to be fully developed, and has attained its peak physical and mental capacity.

Mature German Shepherds are fully grown in size and weight. And provided the GSD was properly socialized as a puppy, then you have a pooch that’ll make an excellent companion, and with which you can create lots of beautiful memories.

How Much Should A Young German Shepherd Puppy Eat?

How many cups of food you should feed a young German Shepherd puppy is dependent on factors such as the dog’s weight, growth rate, age and recommendations from your vet.

However, the generally accepted guidelines for feeding young German Shepherd puppies are:

  • From 8 weeks old to 12 weeks old – 1 to 1½ cup of food per meal
  • From 12 weeks old to 6 months old1½ to 2 cups of food per meal
  • From 6 months old to 12 months old2 to 3 cups of food per meal
  • 12 months old and above3 to 3½ cups of food per meal

How Many Times A Day Should You Feed Your Young German Shepherd Puppy?

The recommended frequency of feeding for a German Shepherd puppy is as follows:

  • From 8 weeks old to 12 weeks old4 times a day
  • From 12 weeks old to 6 months old3 times a day
  • From 6 months old to 12 months old3 times a day
  • 12 months old and above2 times a day

You can also feed your German Shepherd puppy snacks and treats in between meals, but the frequency with which you do this should reduce as the pooch grows older.

What Should You Feed A Young German Shepherd Puppy?

As earlier seen, German Shepherd dogs have several stages of development, and it is essential that you feed your dog the appropriate meals at each stage to provide the levels of nutrition that are required for healthy development.

That said, young German Shepherd dogs typically need to eat more than the adult pooches. And the young GSD’s meal should also contain a higher percentage of fat and protein compared to that of the adult dog.

From Birth To 8 Weeks Old

The period immediately after a German Shepherd’s birth is very crucial, and the puppy must be appropriately fed to ensure proper growth and development.

Puppies should be left with their mothers, for at least eight weeks after birth, so that they can be fed the nutrient-rich colostrum which contains antibodies necessary to fight diseases and infections.

If, for one reason or the other, the puppy has to be prematurely weaned, then the best thing to do is consult a vet for the prescription of a specific infant formula for the pup.

From 8 Weeks Old To 12 Weeks Old

Once the puppies are weaned – typically around eight weeks – they should be placed on a special puppy mush diet, which is usually prepared by soaking regular dog kibble in goat milk.

Adding goat milk makes the food easily digestible for the puppy, and by soaking the kibble, you’re making it easy for the young pooch to eat. For GSD puppies that don’t have teeth, you can add water to the mixture to make it even easier for the pooch to lap up.

12 Weeks Old To 6 Months Old

As the German Shepherd puppy grows older, you can decrease the amount of goat milk you add to its kibble, till you begin to feed the puppy dry, hard kibble. You can also add tiny amounts of fresh ingredients such as boiled eggs, unsweetened yoghurt and canned pumpkin to improve taste and flavour.

6 Months And Above

This phase is highly important and it marks the transition of the young German Shepherd from puppy to adult food. You can continue to feed the pup kibble, but you need to ensure the food is of the highest possible quality.

And if you will rather switch to wet dog food, then we suggest you pick one that is specially formulated for young German Shepherd dogs such as the Pet Plate.

German Shepherd puppies require a protein-rich diet to grow into the strong and athletic dogs they are designed to be, and the Pet Plate’s meat-based formulation caters adequately to this. Additionally, you have the option to submit your GSD puppy’s physical characteristics to Pet Plate to get a tailored food plan for the pooch.

Can You Overfeed A German Shepherd Puppy?

German Shepherd puppies, like all other dogs, are prone to weight issues; Hence, to prevent this from happening, you should avoid overfeeding a Shepherd puppy.

Sure, by overfeeding a German Shepherd puppy, you will be encouraging significant weight gain, and rapid growth. But this weight gain is highly unhealthy, and you’re only placing the pup at risk of suffering from health conditions such as hip dysplasia in future.

How Can You Tell How Big A German Shepherd Will Get?

Most German Shepherd dogs end up being medium-sized, but some can also grow to be fairly large. And you can tell how big a German Shepherd dog will grow to be, by monitoring its weight from birth, using values in the charts provided above, as a guide.

Factors determining the size of German Shepherd dogs include:


One way of telling how big a German Shepherd puppy will get is by taking a look at the size of its parents. And this is, most times, accurate, considering the fact that the German Shepherd dog is purebred.

If the puppy’s parents are on the large side, then you can expect the pup to grow to become a relatively large dog. And in the same vein, if the parent German Shepherds are medium-sized, they will most likely produce medium-sized puppies.


Knowledge of your German Shepherd’s gender can help you make a calculated guess on how big the pooch will grow to be.

That said, the average size for a male adult German Shepherd is between 65 to 90 lbs, while the female GSDs typically weigh between 50 to 70 lbs as adults.

When it comes to height, adult male German Shepherd dogs typically stand between 24 to 26 inches tall, while the females average between 22 to 24 inches in height.


The effects may not be as pronounced as those of the factors listed above, but what your GSD is fed while growing also plays a role in how big such a pooch will get.

German Shepherd dogs that are fed a high-quality diet that contains all the nutrients required for healthy dog growth are more likely to attain the weight standards expected of a GSD, compared to those that are fed nutritionally lacking meals.
