Family movie with a dog Satan and a dialogue with a priest

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, so he builds "wooden" or "earth" 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: "Satan was name of my 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.

It is extremely hard question. Thank you in advance

Rejected:
Seclusion Near a Forest (1976) - there is dog named Devil, not Satan and he isn't buried
Jutro bedzie niebo (2001) - there is dog no name, although he is buried
