Musannaf Ibn Abi Shaybah

Hazrat Adi bin Hatim (may Allah be pleased with him) narrates that if a dog drinks the blood of the prey, then do not eat its prey, because what you have taught it, it has not learned.

Hazrat Ata (may Allah have mercy on him) says that if a dog eats the meat of the prey, then do not eat it, but if it drinks the blood, then you can eat it.

Hasan (may Allah have mercy on him) said: If a dog eats the flesh of the game, then do not eat it, and if it drinks its blood, then eat it.

Hasan (may Allah have mercy on him) said: If a dog eats the meat of the game, then still eat it, and if it drinks its blood, then still eat it.
