Musannaf Ibn Abi Shayba 12:23

Abu Bakr narrated to us, he said: Abdullah ibn Numayr and Waki’ narrated to us, from Ibn Abi Dhi’b, from Bukayr ibn Abdullah ibn al-Ashajj, from Humayd ibn Malik, who said: I asked Sa’d ibn Abi Waqqas, and I said: "We have predatory dogs that we send out for hunting, and they eat [from the prey] and tear it." He said: "Eat [it], even if there remains nothing but a morsel."
