Is Black A Standard Color In Miniature Schnauzers?
Solid black is accepted by the AKC and the FCI for all Schnauzers.
What Does A Black Miniature Schnauzer Look Like?
Black Miniature Schnauzers are solid black.
Most of them have a dominant black pattern, but recessive black is also in this breed. Both patterns instruct pigment cells to produce only eumelanin which gives a solid black coat color.
It is normal for ” broken down pigment” or older puppy coat to show reddish shades in some areas. A small number of black Miniature Schnauzers might have a seal pattern or show graying.
The AKC allows for a small white spot on the chest while the FCI does not tolerate residual white.
“Ideally, the black color in the topcoat is a true rich glossy color with the undercoat being less intense, a soft matting shade of black. […] A small white spot on the chest is permitted [..].”
AKC Breed Standard
“Pure black with black undercoat.”
FCI Breed Standard
Black Miniature Schnauzer Nose Color
A dog’s nose gets its color only from its eumelanin pigment.
Dogs with a black-based pattern will always have a black nose. Also, any visible skin pigment like eye rims and lips and even the nails and paw pads will be black.
“[…] the nose must be solid black.”
AKC Breed Standard
“Well developed nose leather, always black“
FCI Breed Standard
Black Miniature Schnauzer Eye Color
Eye color is determined by eumelanin color and pigment density.
A black Miniature Schnauzer with its black eumelanin typically has dark brown eyes.
“Eyes – Small, dark brown and deep-set.”
AKC Breed Standard
“Eyes […] dark with lively expression.”
FCI Breed Standard
Black Miniature Schnauzer Coat Type
Miniature Schnauzers are double-coated with a wire-haired coat type.
Their topcoat is harsh and wiry with their leg furnishings a little longer and softer.
L/-
short-haired
F/F
furnished
N/N
non-curly
All Schnauzers are fixed for furnishings (F/F), they always have a beard and bushy eyebrows.
Some Miniature Schnauzers seem to be long-haired (l/l). And a few even have a curly variant (Cu/-).
“Coat: Double, with hard, wiry, outer coat and close undercoat. […]”
AKC Breed Standard
“The coat should be wiry, harsh, and dense. […] The hair on the limbs tends to be less harsh. […] Typical characteristics are the not too soft beard on the muzzle and the bushy eyebrows ...”

Black Miniature Schnauzer Genetics
Black Miniature Schnauzers typically have a black-based dominant black pattern.
But recessive black also occurs in this breed.
Basic Pattern
The A, K and E locus combined are responsible for a dog’s basic pattern. They tell pigment cells when and where to produce either eumelanin or phaeomelanin.
Most black Miniature Schnauzers have a dominant black pattern (E/- KB/-) .
But some of them are recessive black (E/- ky/ky a/a).

1) Dominant Black
A LOCUS
doesn’t matter
KB/–
dominant black
E/-
wild type
A Locus (Dominant Black)
Most traditional Mini Schnauzers have a aw/- or at/at genotype at their A locus.
However, dogs with dominant black do not express their A locus pattern so it doesn’t matter.
K Locus (Dominant Black)
A dominant black dog has at least one copy of KB.
K locus overrides a dog’s A locus pattern since it makes all pigment cells produce only eumelanin.
E Locus (Dominant Black)
At the E locus, there is either a wild-type E or sometimes a mask Em allele.
Both do not further affect a black dog’s color. What matters is that black Mini Schnuazers are never e/e.
2) Recessive Black

A Locus (Recessive Black)
Miniature Schnauzers with a recessive black pattern are a/a at their A locus.
K Locus (Recessive Black)
A recessive black dog can express his pattern (ky/ky).
E Locus (Recessive Black)
Both an E and Em do not affect a recessive black pattern.
What matters is that dogs are not e/e since this would override their solid black pattern.
Pigment Colors
Black Miniature Schnauzers have black eumelanin.
Some genes determine the actual colors in a dog’s pattern.

Phaeomelanin
A solid black dog does not produce phaeomelanin.
Eumelanin
Dogs with a B/- D/D genotype will produce black eumelanin.
Other Traits
Traditionally, Miniature Schnauzers do not have white markings or merle.
Some traits can modify a pattern by removing pigment or further modifying colors:

White Markings
Solid Miniature Schnauzers have a solid coat (S/S).
If they had piebald spotting (sP), they would be Parti Black & White.
Still, some black Schnauzers can have residual white markings.
“A small white spot on the chest is permitted, as is an occasional single white hair elsewhere on the body.”
AKC Breed Standard
Merle
Purebred black Miniature Schnauzers do not come in merle.
Seal
The FCI standards mentions “brown undercoat” as an off-color. Maybe this not only means rusting or sunbleaching but maybe refers to a seal pattern in black dogs?
Graying
Some Schnauzers in the US have progressive graying. This can produce an off-color in black dogs.
“The stripped portion is free from any fading or brown tinge.”
