Caniche

This grotesque black comedy--that's about the best term for it--centers on a brother and sister, both 40-ish, who live alone in a rambling but decrepit mansion, completely interdependent while getting on each others' nerves. Mostly they obsess over wheedlng more money out of an elderly aunt who seems rather nasty herself, but is understandably rather sick of being squeezed by these disagreeable layabouts.

At a certain point the situation changes, and the siblings inherit the aunt's money. The mansion gets an extensive immediate makeover, but relations between the two only deteriorate further, particularly because the brother's mental instability and apparent incestuous feelings become more obvious. He's jealous--not just of the older man she's now seeing, but of the poodle she is incessantly fussing over, somewhat like a doting parent and somewhat (diusturbingly) like a lover.

You know all this isn't going to turn out well. The attention paid to dogs in general (there's also some kind of nearby kennel that the brother frequently visits) lends a certain thematic novelty to what's otherwise a "Baby Jane"-like psychological thriller of two difficult personalities whose sickness festers in isolation, feeding off mutual discord. It's an interesting early Bigas Lunas effort.
