Keep dogs for hunting or herding purposes; wash utensils licked by a dog seven times; rub with earth once after washing; maintain cleanliness standards according to Islamic teachings .

The Prophet Muhammad (sal Allaahu alayhi wa sallam) taught us about keeping dogs for hunting and herding purposes. He ordered the killing of dogs, but granted permission to keep them if they were used for these two activities. He also instructed that if a dog licks a utensil, it should be washed seven times and rubbed with earth the eighth time in order to purify it from any impurities or germs that may have been transferred from the dog's saliva. This hadith teaches us about cleanliness as well as how we can use animals such as dogs in beneficial ways while still maintaining our religious obligations.
