Stages of the German Shepherd’s Growth

The Neonatal stage

The first stage of a dog is the neonatal stage which starts from the second it is born till when it is 3 weeks old. It is the most vulnerable period for the German Shepherd, where the puppy needs a lot of care and pampering. At this stage, the German Shepherd puppy develops his sense, opens his eyes for the first time, listen to sounds, and learn how to walk and crawl. These little pups are completely dependent on their mothers, who keep them warm.

German Shepherd Puppyhood

The puppyhood of a dog lasts for about 5 to 6 months and includes the neonatal stage. Mostly, German Shepherds finish their puppyhood by six months, and in these six months, your Shepherd pup is going to experience stages like the neonatal stage, socialization stage, Juvenile period, etc.

A healthy German Shepherd puppy will gain a consistent weight of 5 – 10 % and will double its birth weight during the first week of its life. They reach physical maturity by 12 – 18 months, and their growth rate slows down at six months. Right after the neonatal stage which ends at the 3rd week, your pup will begin to discover the world with its newly developed senses.

The Socialization Stage

The socialization stage of the German Shepherd begins right after the 7th week of its birth and lasts till the 12th week. In this stage, the puppy introduces itself to different kinds of people and socializes away from their family. They will begin to interact with other humans and other dogs around them. At the same time, they will be developing the ability to bark, and their ears will stand up. They can even become prone to developing trauma, so make sure you keep them safe.

The Puppyhood Seniority Stage

This stage begins at the 12 weeks of the puppy’s life and lasts till 16 weeks. In this period, you need to train your puppy as they might try biting or nipping you during this stage. At the same time, they will play competitive games with other dogs.

The Juvenile Stage

The Juvenile stage is the last stage of puppyhood which starts from 3 months after the puppy’s birth and lasts till six months. In this stage, the puppy becomes stubborn. They might not listen to you, but be patient because only patience can help them become obedient dogs. The German Shepherd would easily eat and interact with others in this period and will also lose their milk teeth.

The Stage of Puberty

The stage of puberty, also known as the adolescence or the sexual maturity stage of a German Shepherd, begins from the 6th month and lasts till the 16th month. You would be able to see many physical changes during this period, but they will go through different hormonal changes. You can keep your dog spayed or neutered during this period. Your dog can also experience fear and breakdowns. For example, they might forget how to perform basic tasks. The German Shepherd may also become aggressive at this stage. However, these hormonal changes would get better with time.

The Stage of Adulthood

After the stage of puberty, the German Shepherd will enter adulthood. It begins from 1 year and lasts till three years. In this stage, your dog would be fully grown to a normal German Shepherd size. Your dog would adopt more matured and calmed behaviors and will continue to grow until 36 months, where most will be done by 24 months. The dog is going to be more active and will require more exercise. You can switch to adult food at this stage to fulfill their nutrition requirements as they will be moving towards seniority.

The Final Seniority Stage

The final seniority stage is the last stage of growth. It occurs after your German Shepherd has reached the age of 6 – 10 years. They are now no longer adult dogs and are now senior dogs. They will need a lot of care as senior dogs can develop different health issues like joint pain, hip dysplasia, etc.
