When you let loose your trained dog (after a game) and you mention the name of Allah, then eat what it catches for you

‘Adiyy ibn Hātim asked the Messenger (may Allah's peace and blessings be upon him) about hunting with his trained dogs. The Messenger of Allah (may Allah's peace and blessings be upon him) told him to eat whatever the dogs catch as long as he mentions Allah's name on letting them loose after the game, and as long as no other dog hunts with them. If he finds another dog, then he should not eat from it because he only mentioned the name of Allah on sending his dog, not someone else's dog.

Moreover, the Messenger of Allah (may Allah's peace and blessings be upon him) informed him that if he threw his spear and it pierced the animal and spilled its blood, then he could eat from it so long as he mentioned Allah's name. If the spear, however, stroke the animal with its blunt side, and it died, then he should not eat from it. In this case, the animal died from being hit, like an animal that dies from falling down or from being hit by horns.

Also, if one sends his trained dog and the game is found alive, without being killed by the dogs, then it is necessary to slaughter it at that moment. Eating it is permissible even if other dogs are found with it. He also asked him about hunting with an arrow if he mentions Allah's name, and the Prophet (may Allah's peace and blessings be upon him) informed him that it is permissible for him to eat the game that he hits by his arrow.

If he finds it a day or two later with nothing but the trace of his own arrow, then it will be permissible for him to eat from it. However, if he finds it drowned in water, then he should not eat from it because he does not know whether it died from drowning or from his arrow.
