A pit bull roaming around her Westchester County, NY, neighborhood prompted a call to the cops due to her loud barking. But it turns out there was a method to Sadie's madness, per People: The pooch was apparently trying to alert anyone who would listen that something was terribly wrong back home. CBS New York reports that when the Tuckahoe Police Department first got the call about Sadie on Wednesday afternoon, they arrived on the scene and found Sadie in the street—but when they approached her, she dashed away. A chase led the cops back to the house of Sadie's owner, Serena Costello, where police spotted an open sliding glass door and smelled gas.
Con Edison and the local fire department were called, and a gas leak in the home was confirmed. Authorities say there could have been an explosion if the gas had been allowed to build up much more. Meanwhile, Sadie looks to have been frantic to let someone know what was going on (Costello and her young daughter weren't home): Blood and claw marks were found near the front door, which Sadie apparently scratched up in a panic before somehow figuring out how to open the sliding door in the kitchen. "It's just so out of character for her to do," Costello says of Sadie escaping from the house. "She is our hero. She saved our lives." (A dog saved a little girl from a rattlesnake.)
