As a mixed-breed dog, the Border Aussie has a higher probability of having blue eyes than pure breeds. Mostly, Aussies with the desired colored eyes have a merle-patterned coat.
Border Aussies are a cross between Australian Shepherds and Border Collies. If both of its parents have blue eyes, the chances of the offspring having blue eyes is increased significantly, When only one of its parents has the said color eyes, there is around 25% to 50% probability of their puppy possessing blue eyes.
The Shepherd-Collie cross can also be found in coats of different colors, including red, tan, liver, tricolor, and merle.
