I barely remember a few things about a movie I watched when I was a kid (the plot is not for kids though!), and I'd like to see if somebody can help me find it:
- The main characters are a mom and her son
- one way or another, a dog (may be a rottweiler) is an important character of the story
- the mom is particularly concerned about the dog's aggressiveness
- the mom starts seeing the dog bigger and bigger as the movie goes on (which makes it ok to classify the movie at least partly fantasy???)
- towards the end of the movie the dog is as big as a house, and I kinda remember that it literally grows so big while inside the house, thus taking the roof off the house
- afterwards the woman is shown in a hospital or a psychiatric unit, with the mark of some kind of lobotomy on her forehead.
