💙 Blue Eyes in the Harlequin Beauceron 💙
With another litter of harlequin puppies currently developing those unmistakable blue eyes, I thought it was worth taking a closer look at what the Beauceron standards actually say about them as well as what blue eyes do, and do not, tell us about a dog.
The FCI standard describes the Beauceron’s iris as dark brown, never lighter than dark hazel. However, it specifically states: “For the harlequin variety, wall eyes are admitted.” Its disqualifications likewise identify eyes that are too light or wall eyes as disqualifying except in harlequins.

The AKC standard follows the same basic principle: the eyes should be dark brown and never lighter than dark hazel, while walleye is acceptable in the harlequin. Walleye remains a disqualification in the Black & Tan.

An interesting detail is that neither standard specifies that only one eye may be a wall eye nor does either standard explicitly state that two blue eyes constitute a disqualification. The wording is simply that wall eyes are admitted in the harlequin. That is an important distinction from saying that the standard specifically requires one blue eye or expressly permits two.

So, what exactly is a blue eye?
Blue coloration occurs when there is little or no pigment in the iris stroma; the blue appearance results from the way light scatters through that tissue. It is therefore fundamentally a pigmentation characteristic, not a diagnosis of poor eyesight. Blue irises contain less pigment, but current evidence does not establish that healthy blue-eyed dogs experience clinically significant increased UV damage simply because of their eye color. Some blue-eyed dogs may lack a tapetum lucidum, which changes how their eyes reflect light and may affect low-light optics but that is different from being unable to tolerate bright sunlight.
Blue eyes in harlequin Beaucerons from a normal pairing with a black & tan should not be confused with a double Merle (harlequin) breeding that produces blue eyes. This is also where eye color and hearing should not be conflated. Pigment-associated congenital deafness can occur with certain pigmentation patterns and may be unilateral or bilateral. A puppy’s eye color alone cannot establish whether it can hear; when there is reason for concern, objective testing such as BAER is considerably more informative than observation.

As for the aesthetic question, my own preference remains firmly with the traditional dark Beauceron eye. I think that deep brown eye contributes to the breed’s characteristic frank, confident expression and complements the black-and-tan or harlequin coloring beautifully.
That said, there is no denying that a blue-eyed harlequin is striking. A friend once described the expression as having a “haunted Victorian child look” and I have never been able to unsee it.
Beautiful? Absolutely.
My preferred Beauceron eye? Still dark brown.
And perhaps the most interesting part is that the breed standards leave considerably more room for that unusual harlequin expression than many people realize.
