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

He who kept a dog other than one meant for watching the herd or for hunting would lose every day two qirat of his good deeds. 'Abdullah and Abu Huraira also said: Or dog meant for watching the field.
