During the episode, "I Believe the Children Are Our Future," there is a movie right in the beginning playing in the background. Originally, I thought it was Cujo.

There was a woman in a car with the window half-rolled down and what looked like a yellow lab snapping at her from the outside. She was scared. The reason I believe it's not Cujo is because the dog looked more like a Yellow Lab than a St. Bernard (which is what I believe Cujo was).

Anybody have any idea what this movie was?

Thank you!

According to IMDb's movie connections, it was Cujo.
