The Prophet (peace_be_upon_him) said: Were dogs not a species of creature I should command that they all be killed; but kill every pure black one.

Narrated Jabir ibn Abdullah:
The Prophet of Allah (peace_be_upon_him) ordered to kill dogs, and we were even killing a dog which a woman brought with her from the desert. Afterwards he forbade to kill them, saying: Confine yourselves to the type which is black.
