The Australian Shepherd, endearingly known as Aussie, is loved heaps by pet parents and potential pet parents alike – around the world. They are famous for their charming looks, protective zeal, and stamina. On average, they tend to grow about 23 inches in height and weigh up to 65 pounds.

Nonetheless, when it comes to determining their growth chart, there are a variety of factors such as age and gender that can come into play.

The Four Stages of An Aussie’s Development

The growth of any dog is probably the first concern that comes to our minds when we decide to buy or adopt one. This holds utmost importance as most of us want to ensure we have ample space for our newest family member in our homes; and don’t want him/her to feel suffocated as they grows in size and love.

It is also pertinent to mention that Australian Shepherds come in two different sizes – miniature and standard. The miniature ones are known to become fully grown in just 12 months, while the standard aussie will take up to 16 months to grow fully. So, your puppy’s growth can also depend on which type of Australian Shepherd it is.

Besides that, before adopting any dog, it is also good to educate yourself on the different developmental stages they will undergo. This not only prepares you for what to expect going forward, but also equips you with the right information to be able to take care of your dog as he goes through each one. After all, he’s going to need you to look out for him!

Below, we discuss these stages in detail:


The first and foremost stage of an Aussie’s growth is puppyhood. This will last for anywhere between 4 to 6 months. During this time, your doggo slowly grows and develops his/her senses. Let’s walk through how this unfolds:

0-14 Days

Taste and touch will be completely developed in this stage of life, but the other senses will not have developed to that extent. This is because the puppy still relies on his mother for all basic requirements.

14-28 Days

This stage of puppy growth is known as the transitional stage. The faculties of hearing and smell will begin to grow, as well as the eyes and teeth. The puppy will start to stand, wag its tail, and bark. Also, it will begin to interact with its littermates more.

3-12 Week

This will be the stage when the eyesight of the puppy is fully developed. You can expect him to become more aware of his surroundings.

During this time, play becomes increasingly crucial since it is the first way for a puppy to learn important skills such as improving physical coordination, developing social boundaries, and learning the inhibited bite.

Furthermore, by the end of the sixth week, puppies should be weaned and begin eating 5-6 tiny pieces of puppy food throughout the day. Puppies are at the peak of their puppyhood at eight weeks and are ready to leave the breeder and join their new family.

A puppy’s senses are fully developed by the time it is 7 to 9 weeks old, and house training can begin.

This is also when the pup becomes aware of the “pack” hierarchy for the first time.

3-6 months

Around the age of 4 months, a puppy begins to resemble a dog rather than a puppy. This is still the best time to train.

Play progresses as teething and chewing begin. The puppy has reached full maturity and is ready to move on to the next stage of life.

When the puppy is five months old, you can take it on short walks with you, but don’t overdo it.

Furthermore, a 6-month-old Aussie puppy will have gained around 2/3 of its adult weight and enter the teenage stage.

Its adult coat will begin to grow, and it will become more independent but also fearful and disobedient. Please note that proper training and socialization at this stage are crucial.


This stage starts after the first six months of your Aussie’s puppyhood. It usually lasts between 7-12 months.

7-9 Months

It is the stage in which the puppy grows gradually and becomes bigger. You will also witness that the Aussie is maturing and finally starting to look like a big dog.

As a puppy grows and gains strength, it may challenge humans as it investigates its powers. It might begin to see the rank structure in a new light.

Furthermore, watchdog qualities, reserve with strangers, and authoritative conduct are common at this age. Owners should be informed that these traits can be very, shockingly strong during this time.

Dogs who were social as puppies may begin to avoid contact with strangers as they grow older. Dogs that had never been watchdogs suddenly become so, and they might be difficult to control while doing so.

A puppy will enter the second chewing phase at seven to nine months, and if it hasn’t been spayed or neutered, it will begin to experience the initial stages of sexual activity.

If you do nothing, the dog’s relationship with you will undoubtedly change. If you enhance your training and control, the dog will stay where it belongs: beneath you in the hierarchy, an eager and compliant partner.

9-12 Months

The adolescence stage comes to an end after the Aussie is one year old.

Around 10-11 months of age, Australian Shepherds reach sexual maturity. If you own a female pet, keep in mind that it may go into heat around this time.

You might notice some change in behavior due to the developed sexual behavior.


When the Aussies reach adulthood, they are usually very energetic. It would help if you trained this pooch in the earlier stages.

Adult Australian Shepherds who have been properly socialized and taught can usually manage almost any challenges. They are usually fully grown by this time and have completely developed senses. However, there are chances of them growing a little bigger.

Moreover, adult Aussies with watchdog qualities are common, but a well-trained Aussie should be able to tell when it’s appropriate to be a watchdog.

They belong to the herding dog category, so you must make sure that you take them for a walk. Your dog will thrive in competitive dog sports if you have the time and commitment.

Aussies require a job, and if they are not trained and stimulated, they will be dissatisfied. This is not a dog you can leave unattended in the backyard for several hours. So, make sure the exercise session is not missed.

You can try any kind of exercise you want but remember the goal should be to curb the stamina this pooch has during this stage of life.

Old Age

The last stage on our list is seniority. It is usually the time when your Aussie reaches 8-10 years. The Aussies have a lifespan of 14/15 years, and their health is majorly affected as they grow old.

There can be a variety of diseases that can affect the Aussie at this stage. You have to take proper care and make sure that it is safe. You might have to make frequent visits to the doctor and get your Aussie checked.

Some of the other changes are seen throughout these stages. Your Aussie will grow more or less like other dogs, but the significant difference will be their herding instincts.

You have to be very determined to train your Aussie. If you ignore their small aggressive moves, you will face difficulty in the future.
