At this point, the owners are not supposed to handle the animals unnecessarily and concentrate on giving them a warm, clean and stress free environment.
2-4 weeks: The Transitional Period
At about two weeks old, there are exciting changes.
Puppies start to:
- Open their eyes
- Hear sounds

Puppies are curious and active during these weeks. They start to investigate the world around them and acquire the necessary social skills.
Key milestones include:

- Beginning house training
- Developing bite inhibition
- Receiving first vaccinations
- New friends and pets.

3-6 months: Accelerated Development and Learning
At this stage, German Shepherd puppies develop very rapidly.
They become:
- More independent
- Highly playful
- Quick learners
- Physically stronger

- Sit
- Stay
- Come
- Leave it
- Being on a leash.
Positive reinforcement and consistency develop a lifetime of good behavior.
6-12 Months: The Adolescent Stage
According to many owners, this stage is the teenage years.
Even though your German Shepherd might appear almost mature, they are still growing mentally and emotionally.
Common characteristics include:
- Increased energy
- Testing boundaries
- Strong curiosity
- Higher confidence

German shepherd males tend to keep increasing in height at this stage and females might be able to attain most of their adult height at an earlier stage.
Exercise is more and more significant, but at the same time, do not overdo high-impact exercises until the growth plates have matured.
12-24 months: Development of the Young Adult
In one year, most German shepherds have attained their adult size.
However, they continue developing:
- Muscle mass
- Chest width
- Strength
- Coordination
- Emotional maturity
Working-line German Shepherds can be very active at this age and can enjoy some advanced training exercises such as:
- Agility
- Tracking
- Obedience competitions
- Scent work
- Protection sports
This intelligent breed must be mentally stimulated as much as it is exercised.

At this age, they tend to possess:
- Fully developed muscles
- Strong bones
- Stable temperament

When well taken care of, most German Shepherds are still active in their old age.

Factors That Influence German Shepherd Growth
The rate at which your puppy develops and its success is dependent on several factors.
Genetics
The size, body structure, and growth rate of an adult dog is largely dependent on the parents of the puppy.
German shepherds that are used as working dogs tend to be leaner in their body structure whereas show line dogs can be wider-bodied.
Nutrition
Puppy food that is of high quality contains the necessary nutrients to develop healthy bones and muscles.
Find diets that include:
- High-quality protein
- Healthy fats
- Calcium
- Phosphorus
- DHA to develop brain.
Do not overfeed, because gaining weight too fast puts you at risk of joint problems.
Exercise
- German shepherds need to be active but not overly jumping or running long distances as their bones are still growing.
- Exercising according to age helps in keeping joints and muscles healthy.
Veterinary Care
Regular examinations enable the veterinarians to check:
- Weight
- Growth rate
- Vaccinations
- Parasite prevention
- Dental development
Many of the long-term health problems can be prevented with early intervention.
