ABUDAWUD 71:
from Aḥmad b. Yūnus —
The Prophet (sal Allaahu alayhi wa sallam) said: The purification of the utensil belonging to any one of you, after it has been licked by a dog, consists of washing it seven times, using sand in the first instance. Abu Dawud said : A similar tradition has been narrated by Abu Ayyub and Habib b. al-Shahid on the authority of Muhammad.

عن احمد بن يونس —
عَنِ النَّبِيِّ ﷺ قَالَ طُهُورُ إِنَاءِ أَحَدِكُمْ إِذَا وَلَغَ فِيهِ الْكَلْبُ أَنْ يُغْسَلَ سَبْعَ مِرَارٍ أُولاَهُنَّ بِتُرَابٍ
