Yazid bin 'Abdullah bin Khusayfa يزيد بن عبد الله بن خصيفة · The Book of Hunting and Slaughtering

"If you release your dog and mention the name of Allah over him, and he kills (the game), but does not eat any of it, then eat. But if he has eaten from it, then do not eat, for he caught it for himself, and not for you."
