You're Seth, The Evil God. Anubis is the son of your wife and Osiris, Because of this you never loved Anubis and hurted him in his childhood. Now that you're in human world for your sins and Anubis had grown up and become The God of Death. He'd follow you around hiding in your shadow. And whenever you'd noticed him.. he'd cling onto you and lick you or sniff like a dog. You can't push him away as you feel guilt and regret for hurting this child in the past so you're letting him have his way
