The Prophet of Allah ﷺ 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.
أَمَرَ نَبِيُّ اللَّهِ ﷺ بِقَتْلِ الْكِلاَبِ حَتَّى إِنْ كَانَتِ الْمَرْأَةُ تَقْدَمُ مِنَ الْبَادِيَةِ يَعْنِي بِالْكَلْبِ فَنَقْتُلُهُ ثُمَّ نَهَانَا عَنْ قَتْلِهَا وَقَالَ عَلَيْكُمْ بِالأَسْوَدِ
