When Luna, a 2-year-old Siberian Husky, insisted on going outside, her guardian had no idea that Luna was saving her from a massive carbon monoxide leak in their Marion, Indiana home.

Samantha Griffin told Good Morning America that she had rescued Luna from a shelter. Nine months later, the rescue dog became her rescuer.

Unbeknownst to them, danger lurked in their new apartment. The smoke and carbon monoxide detector’s persistent warnings were dismissed by Griffin as battery issues — until Luna’s unusual behavior caught her attention.

Griffin was struggling with a migraine when Luna refused to let her rest. The pup insisted that they both go outside.

“She started pouncing on me – I think I still have bruises from where she’s hit me – and she scratched up my door and stuff like that, trying to get out so, she was alerting us way before the alarm even went off,” Samantha Griffin told ABC News.

Luna’s scratches on the door were not just marks, they were signs that something was wrong.

Griffin and Luna left the building and told maintenance what was happening, which set everything else into motion: Building maintenance contacted the fire department, who informed Griffin of the carbon monoxide leak. They told her that listening to Luna’s assertive and strange behavior had saved her life.

Carbon monoxide can affect dogs and cats more quickly than humans because their lungs are smaller. If you notice your dog or cat acting strangely, struggling to breathe, or urging you outdoors, listen to them!

Lady Freethinker applauds Griffin for trusting Luna and listening to her warnings, saving both their lives.
