Why Dog Meat is Forbidden in Islam

Dog meat is haram in Islam because dogs are considered as carnivorous animals that have fangs, and the Prophet (peace and blessings of Allaah be upon him) said: “Every animal that has fangs is haraam.”

‏ ‏ أَكْلُ كُلِّ ذِي نَابٍ مِنَ السِّبَاعِ حَرَامٌ 

Sunan Ibn Majah 3233

Dogs are considered impure animals by the majority of the scholars, and their saliva requires purification if it touches a container.

 Shia opinion on dog meat is similar to the Sunni opinion, which is that it is not permissible to eat.
