Im looking for the name of this blk and wht movie, of a little girl with very blond hair, who acted evil?

I saw this in Peru, when I was 7 or 8 years old, which was in 1994 and it was translated in Spanish of course, this movie was in black and white and I just remember one scene, during one night, she was suppose to go to sleep, but she woked up in the middle of the night because a dog was making too much noise im not sure if it was hers, but she pretty much took the dog into the river, that was behind her house, and force the dog to drown...yeah, she was evil like that, and i think she was jealous of her daddy's girlfriend too, im not sure, and she was also mean with other kids....she had very blond straight hair, and i believe bangs too...
