Anubis
Anubis, as the god of death and the afterlife, was closely associated with mummification and burial rites. Egyptian jackals had an association with the dead, as well. They were often found digging up buried bodies and eating them, which may be why Anubis was depicted as part jackal. The priests who mummified the  pharaohs wore costumes to make them appear like Tesem (Pharaoh hound).
