Sayyiduna Amr bin Kharijah al-Thumali narrates: The Prophet (peace and blessings be upon him) sent sacrificial animals with me and said: "If any of them breaks down, sacrifice it, then dip its sandal (which was hung around its neck as a garland) in its blood and with it mark its side; and neither you nor any of your companions should eat from it."
Ahmad recorded it, and al-Tabarani recorded something similar in al-Mu'jam al-Kabir. Its chain contains a narrator, Layth bin Abi Sulaym, who is thiqah (trustworthy), but he is a mudallis (one who practises tadlis).
