A Dog's Heart, a Soviet (TV?) film from 1988, adapted from a Bulgakov short story.
Basically the film opens from the POV and narration of a stray dog (fairly fluent in arcane Soviet regulations) in 1920's Moscow. While in a precarious situation, he get rescued by a rich old professor, worldwide famous and sought by all Moscow to cure sexual impotence. As such the professor is extended significant protection despite being no friend to Bolsheviks and gets to keep his 7 room floor and domestics while the rest of the building is turned into communal flats.
As it turns out, the dog is ultimately needed in some weird transplant experiment (to cure lack of boners) with a freshly deceased crook which succeed... beyond all hopes as the dog slowly transform into an human being. The rest of the movie is the tense and ever degrading cohabitation between creator and creature.
The film is fully available on YouTube with English subtitles (probably not the good framing though, guess it's supposed to be 1.33). It's not lavish but never cheap visually though the cinematography (in B&W) is mostly functional. Cast is good though and the story (apparently very faithfully transcribed into the whole 120mn) is very strong.
It's really a difficult film to boil down because while the themes are obvious, it doesn't really lecture you on the moral answers and you're left to ponder what you think of it. It's never entirely clear (except for his hatred of cats) what Sharikov inherited from his dog side or his human donor and while he grows up to become the caricature of Soviet citizen (crass, vulgar, sympathetic to Soviet mantras benefiting him but not really interested in the higher theory or that eager to die for them), it's hard not to concede he has a point at time on the latter if his rights as a man. And while it's a scathing portrayal of early URSS, the professor ain't exactly sympathetic himself.
Liked it quite a bit and it's a good curiosity, especially if you like Boulgakov style.
