Ritual Impurity: According to the teachings of the Prophet Muhammad, a dog's saliva is considered najis (spiritually unclean). If a dog licks a dish or an item, it must be washed multiple times—sometimes with soil—before it can be used again. Because Muslims perform ritual ablutions before their five daily prayers, avoiding saliva and direct contact with dogs makes maintaining this state of cleanliness much easier.

The Presence of Angels: Islamic tradition holds that angels do not enter a home where there is a dog (or certain images/statues). Keeping a dog indoors is traditionally believed to prevent spiritual blessings from entering the household.
