عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَمَرَ بِقَتْلِ الْكِلَابِ حَتَّى قَتَلْنَا كَلْبَ امْرَأَةٍ جَاءَتْ مِنَ الْبَادِيَةِ
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) ordered the killing of dogs (and we began to kill dogs) to the extent that we even killed the dog of a woman who came from the villages.
