حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَمَرَ بِقَتْلِ الْكِلاَبِ ‏.‏

Salim b. Abdullah reported on the authority of his father that Allah's Messenger (ﷺ) said

Whosover amongst the owners of the house keeps a dog other than one meant for watching the herd or for hunting loses two qirat of his deeds every day.
