What is a miniature Australian shepherd?

A miniature Australian Shepherd is a dog that is the same species as an Australian Shepherd but smaller.

The Australian Shepherd was originally bred in California to herd sheep—a job it does very well. This breed is smart and independent, and it can be difficult to train them. They are also known for being territorial, so they make excellent guard dogs.

While these lovable dogs are smaller than their standard Australian Shepherd counterparts, their size can still vary slightly.

On average, a fully grown Miniature Australian Shepherd stands between 13 and 18 inches tall. It’s important to note that males tend to be slightly larger compared to females, although the difference is not significant.

In terms of weight, the average Miniature Australian Shepherd typically ranges between 20 and 40 pounds. Again, males may weigh slightly more than females, but this can vary depending on factors like genetics, diet, and exercise.

difference between a miniature Australian shepherd and a standard Australian shepherd

Size is the most apparent distinction between the two. As their names suggest, the Miniature Australian Shepherd is smaller than the Standard Australian Shepherd. While the Standard Australian Shepherd can reach a height of 18 to 23 inches at the shoulder and weighs around 40 to 65 pounds, the Miniature Australian Shepherd stands at a shorter height of 13 to 18 inches and weighs between 20 and 40 pounds.

Coat length can also set these two breeds apart. The Standard Australian Shepherd has a medium to long coat. In contrast, the Miniature Australian Shepherd has a similar coat but is slightly shorter in length, which may require less grooming and maintenance.

Growth patterns of miniature Australian shepherds

Puppy Stage

Like any other breed, Miniature Australian Shepherds start as adorable puppies. During this stage, they experience rapid growth and development. Puppies typically double their birth weight within the first week and continue to grow at a steady pace throughout the first few months of their lives. Providing them with proper nutrition, regular veterinary check-ups, and a safe environment to support their healthy growth is essential.


As Miniature Australian Shepherds enter their adolescence, usually around 6 to 12 months, they undergo significant physical and behavioral changes. This stage is often referred to as the “gangly” phase, as their body proportions may seem a bit awkward. They may experience uneven growth spurts, where some body parts grow faster than others. Rest assured, this is completely normal and part of their development process.


When Miniature Australian Shepherds reach 12 to 18 months, they start approaching their full-grown size. However, it’s essential to remember that individual dogs may continue to grow and fill out until they reach around 2 years of age. During this stage, it’s crucial to provide them with balanced diet, regular exercise, and mental stimulation to support their overall well-being and help them reach their full potential.

Factors that can affect the size of a miniature Australian shepherd

Here are some factors that can affect the size of a Miniature Australian Shepherd:


Genetics play a significant role in determining the size of a Miniature Australian Shepherd. The size of their parents and ancestors can influence their growth patterns. If both parents are smaller in size, likely, their offspring will also be smaller. It’s always a good idea to inquire about the size of the dog’s parents when considering a Miniature Australian Shepherd puppy.


Adequate nutrition is crucial for any dog’s healthy growth and development, including Miniature Australian Shepherds. It is essential to provide them with a high-quality, balanced diet that meets their nutritional needs. Proper nutrition supports healthy bone and muscle development, which can contribute to their overall size. Consult your veterinarian to determine the appropriate diet for your Miniature Australian Shepherd at different life stages.

Exercise and Activity Level

Regular exercise is vital for the physical development of Miniature Australian Shepherds. Appropriate exercise helps them maintain a healthy weight and build strong muscles. However, excessive exercise or activities that put excessive strain on developing joints can affect their growth. It’s essential to strike a balance and provide them with age-appropriate training to support their growth and overall well-being.

Health and Veterinary Care

Health issues can sometimes impact the growth of Miniature Australian Shepherds. Certain medical conditions or genetic disorders may affect their growth rate or overall size. Regular veterinary check-ups and preventive care are crucial to assess their health and address any potential concerns that could impact their growth.

Spaying or Neutering

The timing of spaying or neutering can influence the growth of Miniature Australian Shepherds. Early spaying or neutering before reaching maturity can affect their final size. It’s a good idea to discuss the appropriate timing for spaying or neutering with your veterinarian, considering the specific needs of your Miniature Australian Shepherd.

How to care for a miniature Australian Shepherd


Regular grooming is important to keep your Miniature Australian Shepherd looking and feeling their best. Their medium-length double coat requires regular brushing to prevent tangling and matting. A weekly brushing session will help manage shedding and promote a healthy coat. Pay special attention to regular dental care, nail trimming, and ear cleaning to maintain hygiene and prevent potential health issues.


Proper socialization is crucial for Miniature Australian Shepherds to develop into well-adjusted and friendly companions. Gradually and positively expose them to various environments, people, and other animals from a young age. Enroll them in puppy classes or obedience training to enhance their social skills and reinforce positive behaviors. Regular socialization experiences will foster their confidence and ensure they become a well-rounded member of your family.


Like any other dog, Miniature Australian Shepherds should receive regular veterinary care. Schedule routine check-ups to monitor their health, update vaccinations, and address any concerns. Your veterinarian may recommend specific preventive measures to protect against common health issues such as hip dysplasia or certain eye disorders. Ensure they are up to date on parasite prevention, such as flea and tick control, to safeguard their well-being.

Love and Companionship

Miniature Australian Shepherds thrive on love, attention, and companionship. They are known for their loyalty and dedication to their family members. Spend quality time with your furry friend, provide them with plenty of affection and positive reinforcement. They will appreciate being included in family activities and being treated as an integral part of your life.
