I’m looking for a movie from 80’s or 90s - definitely color, not B&W. The protagonist is a boy (he has 8-10 years old). He wants to bury a dog named Satan, ane he builds a grave for this dog (name written on a grave). The priest told him that Satan could not be written on such a grave, and the boy explained that it was the name of his dog. Rather, it was 95% Polish, possibly Czechoslovakian (or it could be Polish dubbing, because my friends from Poland don’t know this movie). Unfortunately, that’s all I remember. Thanks in advance.
