Stories of your pet being a hero

Just interested in some uplifting stories of your pets saving the day, in whatever way you want to interpret that. Waking you up when a fire has started in the house, scaring away a burgler or mugger, and so on.

My dog chases a scary uniformed man off my front porch daily. Except for weekends.

I’m confident that if a fire broke out in our house, she’d go next door to see if they had anything to eat.

Other than that, I’ve got nothin.
