The Iranian Ministry of Culture and Islamic Guidance issued a fatwa against pets in Iran and now places an immediate ban on all advertisements for pets, pet food, and pet products.
The Islamic faith believes dogs are not meant to be house pets because they are dirty, however guard dogs are allowed. Black dogs are viewed unfavorably and should be killed or taken to the closest animal shelter.
In June, Cleric Grand Ayatollah Nasser Makarem Shirza stated that "many people in the West love their dogs more than their wives and children." He referred to dog owners as "blindly imitating the West," and that owning dogs would only end up resulting in "evil outcomes."
Muslims, however are free to live with cats since cats are cherished animals. The Prophet Muhammad owned a cat called Muezza.
