Why Do Australian Shepherds Have Different Colored Eyes?
The main reason Australian Shepherd different colored eyes occur is the merle gene, which directly affects Australian Shepherd eye color and pigmentation.

- Brown eyes
- One blue and one brown eye
- Marbled or mixed eye colors
This is why no two Australian Shepherds look exactly the same.
