If you've spent any time researching Australian Shepherds, you've probably stumbled across terms like Mini Aussie, Mini American Shepherd, and Toy Aussie and wondered...

"Wait...aren't these all the same dog?"

Short answer: they share the same Aussie roots, but the names and classifications depend on the registry. 

Mini and Toy Aussies were developed by breeding smaller Australian Shepherd lines—not by creating a designer crossbreed. AKC recognizes the Miniature American Shepherd as a separate breed, while registries such as ASDR recognize Standard, Miniature and Toy Australian Shepherd size divisions.

But genetically speaking, they are ALL the same, just different sizes.

First, What Do They All Have in Common?

Before we list off any differences, let's get the similarities these dogs have:

✅ They're incredibly smart.

✅ They're loyal to their people.

✅ They're athletic.

✅ They learn quickly.

Energy Level and drive are NOT based on size; they come from the parents. We are more like our mom than we want most days, LOL. Our dogs are the same.

How Big Do Toy Aussies Get Compared to Mini Aussies?

ASDR's published standard puts Toy Australian Shepherds at 10–13.99 inches and Miniatures at 14–17.99 inches.

What's the Difference Between a Toy Aussie and a Standard Australian Shepherd?

ASDR places Standard Australian Shepherds at 18–23 inches, Miniatures at 14–17.99, and Toys at 10–13.99. AKC's Australian Shepherd range is 18–23 inches depending on sex, while its Miniature American Shepherd range is 13–18 inches depending on sex.

Things to Consider:

Mini Aussies thrive when they have jobs to do. As we say (a lot), if you don't give them one, they'll create their own!

In many organizations, such as UKC, ASDR, IBACA, and more, they have "Toy Australian Shepherds", "Mini Australian Shepherds," and "Standard Australian Shepherd"

AKC wanted the mini and the standard to be its OWN breed, so they call the mini a Mini AMERICAN Shepherd, versus the full size is called an "AUSTRALIAN Shepherd.

* In AKC, they do not separate out the "toy" Aussie; it is just included into the mini category.
