This movie contains 11 potentially triggering events.
A dog humps a man's leg, he kicks the dog away and it goes flying out of a window and falls into a lawn mower and is killed. It isn't graphic and is played for laughs (the dog does a very silly sounding howl as it flies through the air). A funeral is held for the dog afterwards.
