the trained dog, and you have pronounced the name of Allah over it, then eat,” and he did not instruct that the game be washed.

As for washing seven times, with one of those washings using earth, that ruling applies exclusively to the vessel when a dog has lapped from it or eaten out of it, whether the dog is a hunting animal or any other kind.

Food Derived from Pig Bones
Question: What is the ruling on eating food produced from a pig’s bones, flesh, or fat?

Answer: If a Muslim is certain that the food is taken from swine or contains any portion of it, it is forbidden for him to eat it. Allah the Exalted says, “Forbidden to you are carrion, blood, and the flesh of swine” (al-Māʾidah 5:3). This prohibition is unanimously agreed upon by the Muslim community; the ban on swine is established by the Qur’an, the Sunnah, and consensus. Therefore, any food that contains any part of a pig is unlawful to consume.
