Let Me Get This Straight, My Grandchild Is A Dog (Levi x Eren One Shot)

Written in response to a #PTR challenge from @In_Hind_Sight

It was supposed to be a great simple Christmas, just Eren and his little corgi, Armin. But when the little dog stammers into the cold winter air and dashes through the tiny hole in the fence straight into the neighbor's house, Eren has no choice but to confront his stoic neighbor who scared the bejeebus out of every single person in own, Levi Ackerman. But when Levi finds no such tiny doggo, he suddenly worries about his own dog. He leads Eren to the attic where both boys are confronted with a shocking site.
