It was Narrated from 'Adiyy bin Hatim the he asked the Messenger of Allah : "I release my trained dog and he catches (game)." He said: "If you release the trained dog and you say the name of Allah over him, and he catches (something), then eat." I said: "Even if he kills it?" He said: shoot with the Mirad." He said: "If it hits (the game) with its sharp point, then eat, but if it hits it with its broad side, then do not eat"
