Mini Aussie Size and Growth Stages Explained

Mini Aussies are a beloved breed, and understanding their size and growth stages is essential for any potential owner. They typically weigh between 13 and 18 pounds and stand between 12 and 14 inches tall.

Their small stature is one of the many reasons people adore them. Mini Aussies are a toy version of the Australian Shepherd breed.

As they grow, Mini Aussies go through several distinct stages. They're born weighing around 8 ounces and measuring 6 inches in length.

Mini Aussie growth is a unique process that can be hard to predict.

These dogs tend to grow at a decently fast rate, almost reaching their full size by six months.

However, because they're smaller dogs, they don't grow as fast as larger breeds.

You can expect them to stop looking and acting like puppies around six months, but some may continue their mental and physical growth beyond that.

The weight and growth speed of Mini Aussies can vary widely, making it hard to predict their adult size.

Dogs of all colors will grow at the same rate, so don't worry about that myth.

By six months, Mini Aussies usually weigh between 20-40 pounds, with most of their weight gain happening before this point.
