What Age Are Akitas Fully Grown? A Comprehensive Guide to American Akita Growth

Before we dive into the specifics of Akita growth, let’s take a moment to appreciate the traits and history of this remarkable breed. Akitas are known for their strength, loyalty, and protective nature. Originating from Japan, they were initially bred for hunting large game, such as bears and boars. Over time, they also became revered as family companions and guardians.

Factors that influence Akita growth

Several factors can influence the growth of an Akita, including genetics, nutrition, exercise, and overall health. Genetics play a significant role, as different bloodlines may have variations in growth rates and sizes. Proper nutrition and a balanced diet are crucial for healthy growth, while exercise and physical activity contribute to muscle development and overall fitness. Additionally, regular veterinary care ensures that any potential health issues are addressed promptly.

Baby Akita Growth Stages

Neonatal stage (Birth to 2 weeks)

During the neonatal stage, Akita puppies are solely reliant on their mother for nourishment and care. They are born blind, deaf, and unable to regulate their body temperature. Their main focus during this stage is to nurse, sleep, and grow rapidly.

Transitional stage (2 to 4 weeks)

As Akita puppies enter the transitional stage, their eyes and ears begin to open, and they become more aware of their surroundings. They start to interact with their littermates and take their first wobbly steps. This is an exciting time as they start exploring their environment and developing their senses.

Socialization stage (4 to 12 weeks)

The socialization stage is a critical period in an Akita puppy’s growth. During this time, they learn valuable social skills, such as how to interact with humans and other animals. It is important to expose them to various stimuli, environments, and experiences to help shape their behavior and confidence as they grow older.

Introduction to solid food (8 to 12 weeks)

Around 8 to 12 weeks of age, Akita puppies are typically weaned from their mother’s milk and introduced to solid food. This is an essential milestone in their growth journey as they transition to a diet appropriate for their age and nutritional needs.

Akita Growth During Puppyhood

Months 3-4

During months 3 to 4, Akita puppies experience rapid growth. They may gain several pounds and increase in height. This is a crucial time for bone and muscle development, so providing a balanced diet and regular exercise is essential.

Months 5-8

Between months 5 and 8, Akita puppies continue to grow but at a slower pace compared to their earlier months. Their body proportions start to change, and they may experience some awkwardness as they adjust to their growing size.

Months 9-12

By months 9 to 12, Akita puppies are nearing their adult size. However, they may still have some growth spurts, particularly in terms of muscle development. It’s important to continue providing them with proper nutrition and exercise to support their physical development.

Akita Growth During Adolescence

Months 12-18

During adolescence, which typically occurs between months 12 and 18, Akita dogs continue to mature both physically and mentally. They may fill out and gain muscle mass, particularly in males. This is also a time when their energy levels may peak, so it’s important to provide them with outlets for physical and mental stimulation.

Months 18-24

From months 18 to 24, most Akita dogs have reached their adult size. However, individual dogs may continue to develop and mature at different rates. It’s crucial to monitor their growth and adjust their diet and exercise accordingly to maintain a healthy weight and overall well-being.

Months 24+

Beyond the age of 24 months, Akita dogs are considered fully grown. While they may not experience any significant changes in size, it’s important to note that their growth and development continue throughout their lives. Providing them with a balanced diet, regular exercise, and proper veterinary care ensures their overall health and longevity.

Factors Affecting Akita Growth

Genetics and Breed Lines

Genetics plays a significant role in determining an Akita’s growth and size. Different bloodlines may have variations in growth rates and overall appearance. It’s important to choose a reputable breeder who prioritizes the health and well-being of their dogs to ensure that your Akita has a solid genetic foundation.

Nutrition and Feeding

Proper nutrition is crucial for healthy growth and development. Feeding your Akita a high-quality diet that is appropriate for their age and size is essential. Consult with your veterinarian to determine the best feeding plan for your growing Akita and monitor their weight to ensure they are growing at a healthy rate.

Exercise and Physical Activity

Regular exercise and physical activity are important for an Akita’s growth and overall well-being. Providing them with opportunities to burn off energy, such as daily walks, playtime, and engaging activities, helps develop their muscles, maintain a healthy weight, and promotes mental stimulation.

Health and Veterinary Care

Regular veterinary care is vital for monitoring an Akita’s growth and addressing any health concerns promptly. Routine check-ups, vaccinations, and preventive treatments are essential to ensure their well-being. Additionally, addressing any health issues, such as orthopedic conditions, at an early stage can help prevent long-term complications.

Signs of a Fully Grown Akita

Physical indicators

There are several physical indicators that can help determine if an Akita is fully grown. These include reaching their breed’s average height and weight, having a well-defined musculature, and the closure of growth plates in their bones. Keep in mind that individual variations exist, and some Akitas may continue to develop slightly beyond the average breed standards.

Behavioral indicators

Behavioral indicators can also provide insight into an Akita’s maturity. As they grow, Akitas generally become more calm and settled in their temperament. They may display increased confidence and self-assurance, while still retaining their protective instincts.

Reproductive maturity

For male Akitas, reaching reproductive maturity is another milestone in their growth. Typically, male Akitas become sexually mature around 6 to 9 months of age. However, it’s important to consult with your veterinarian regarding the appropriate age for neutering to prevent unwanted litters and potential health issues.

Caring for a Growing Akita

Diet and nutrition

Providing your growing Akita with a balanced diet that meets their nutritional needs is crucial. Consult with your veterinarian to determine the appropriate food type, portion size, and feeding schedule for your Akita’s age and activity level. Be mindful of their calorie intake to prevent excessive weight gain, which can negatively impact their growth and overall health.

Exercise and play

Regular exercise and playtime are essential for a growing Akita’s physical and mental well-being. Engage them in activities that are suitable for their age and size, such as daily walks, interactive games, and obedience training. Remember to provide them with a safe and secure environment for their exercise, and always monitor their interactions with other dogs and animals.

Training and socialization

Training and socialization play a vital role in shaping an Akita’s behavior and temperament. Start training your Akita from an early age, using positive reinforcement techniques to encourage good manners and obedience. Additionally, expose them to various people, animals, and environments to promote their social skills and confidence.


Understanding the growth and development of your Akita is essential for providing them with the care they need at every stage of their life. By considering factors such as genetics, nutrition, exercise, and veterinary care, you can ensure that your Akita grows into a healthy and well-rounded companion. Remember, each Akita is unique, and their growth may vary slightly. By observing their physical and behavioral indicators, you can determine when your Akita has reached their full potential. Enjoy the journey of raising and caring for your growing Akita, and cherish the bond you share!
