Not explicitly Norse but the Celtic chooser of the slain? Sounds like a Valkyrie to me.The Morrigan - Shape-shifting Celtic goddess of War, Fate and Death. Story in "The GODDESSES / Psychology of Female Power"
Geri and Freki, Odin's wolfs. When he feasts with the slain warriors (selected by the Valkyries.- the Einherjar) in Valhalla, he only indulges in the divine Mead, from the udders of the goat Heidrun. All other food offered to him he feeds to his wolves.
