Poldek 2004 on netflix

Small dog Poldek lives with a poor old lady in a small one-room apartment. The tenement block is part of a tumbledown grey town out in the nowhere, forgotten by prosperity. The dog is hungry, howles and eats flies that are magically attracted by the old woman. She leaves home every day to seek some eatable stuff. An unsavoury little horrorstory with a lot of action.
