The dog in The Conjuring is a black Labrador named Sadie. She’s not just a background prop. She’s a key player.
Sadie senses the evil before anyone else does. She whines, she barks, she acts like a furry radar for demonic activity. Classic dog move.
And yes, she gets spooked. But she survives the whole ordeal. No dead dogs on the Perron family’s watch.
