When Does a German Shepherd Stop Growing?

German Shepherds are renowned for their intelligence, loyalty, and majestic appearance. As puppies, they capture our hearts with their adorable antics and boundless energy. 

However, like all dogs, German Shepherds don’t stay puppies forever. Many owners wonder, “When does a German Shepherd stop growing?” 

In this comprehensive guide, we’ll explore the stages of a German Shepherd’s growth, factors that influence their growth, and provide expert tips on caring for your furry friend throughout their development.

The Growth Phases of a German Shepherd

Understanding the growth phases of a German Shepherd is crucial for ensuring their well-being. German Shepherds go through several distinct stages of growth:

Puppyhood (0-6 Months): This is the most rapid phase of growth for a German Shepherd. They’ll double their birth weight within the first week and continue to grow rapidly. During this time, their bones, muscles, and organs are developing at an astonishing rate.

Adolescence (6-12 Months): As your puppy transitions into adolescence, their growth slows down, but they’re still developing. Their body will become leaner, and their bones will continue to strengthen.

Young Adult (1-2 Years): By the time they reach adulthood, your German Shepherd will have reached about 80-85% of their final size. However, their bodies are still maturing, and it’s essential to provide them with proper nutrition and exercise.

Maturity (2-3 Years): At this stage, your German Shepherd is considered fully grown. Their growth plates have closed, and their body has reached its maximum size. It’s crucial to maintain a healthy lifestyle to ensure they remain active and fit.

Factors That Influence Growth

Several factors can influence a German Shepherd’s growth:

Genetics: Genetics play a significant role in determining a German Shepherd’s final size. If you know the size of your pup’s parents, you can make a reasonable estimate of their eventual size.

Nutrition: Providing the right nutrition during the growth phases is critical. High-quality puppy food during puppyhood and transitioning to adult food at the right time can ensure proper growth and development.

Healthcare: Regular vet check-ups are essential to monitor your pup’s growth and address any potential health issues promptly.

Exercise: Exercise is crucial for muscle development and maintaining a healthy weight. However, it’s essential to strike a balance to prevent overexertion during the puppy stage.

Understanding Growth Plate Closure

One key aspect of a German Shepherd’s growth is the closure of their growth plates. Growth plates are areas of cartilage near the ends of the bones, and they’re responsible for bone growth. 

In German Shepherds, these plates typically close between 12 to 18 months of age. It’s essential to avoid excessive exercise and strenuous activities during this time to prevent injuries that can affect their growth.

Monitoring Your German Shepherd’s Growth

To ensure your German Shepherd is growing healthily, here are some tips for monitoring their growth:

Regular Weigh-Ins: Keep track of your pup’s weight. Sudden weight loss or gain can be a sign of underlying health issues.

Measuring Height: Measure your dog’s height at the withers (the highest point of the shoulder blades). This can help you track their growth progress.

Consult Your Vet: Your veterinarian is your best resource for tracking your dog’s growth and addressing any concerns.

Common Concerns About German Shepherd Growth

Growth Spurts: Just like human teenagers, adolescent German Shepherds may experience growth spurts. It’s normal for them to appear lanky and uncoordinated during these periods.

Weight Gain: German Shepherds are prone to hip and elbow dysplasia, so it’s essential to monitor their weight to prevent excess stress on their joints.

Slow Growth: If your German Shepherd’s growth seems slower than expected, consult your vet to rule out any underlying health issues.


Understanding when a German Shepherd stops growing is essential for providing them with the best care throughout their development. 

By monitoring their growth, providing proper nutrition, exercise, and regular vet check-ups, you can ensure that your loyal companion grows into a healthy and happy adult dog. 

Remember, every German Shepherd is unique, and it’s crucial to tailor your care to their specific needs. Enjoy the journey as your adorable puppy transforms into a majestic adult!
