The black dot on a German Shepherd Dog’s face is not a mole or a beauty mark, it is a genetic inheritance in coat appearance that often leaves a black circular patch of hair. Underneath it is a collection of nerves, and the thick hairs that sprout from it are whiskers called “vibrissae”. The vibrissae transmit sensory messages to a dog’s brain.
Almost all dogs have this area, but not all have the black mole-like circle. Belgian malinois are another breed which can have this black circular patch of hair.
An actual mole is a skin growth and usually lacks hair.
Vibrissae and whiskers are also found on a dog’s mouth, lower jaw, above their eyebrows and near their ears.
