When a young couple brought their newborn daughter home, their golden retriever, Lora, immediately became attached to her. She barely left the baby’s side.

At first, they thought it was sweet—just a loyal dog being protective. But soon, her behavior became a bit unsettling. Every night, Lora would sit perfectly still by the crib. She didn’t sleep, didn’t eat, didn’t even drink water. She just watched. Always alert.

Concerned, the parents set up a night-vision camera to see what was going on while they slept. What they caught on video sent chills down their spines.

At 3:12 a.m., Lora jumped to her feet and began growling at the window. A hand was slowly pushing through the screen. Within seconds, Lora lunged—barking and snapping until the intruder ran off.

Police later confirmed that a known burglar had been targeting homes with infants. Thanks to Lora’s quick reaction—and the bite she gave him—officers were able to collect evidence that led to his arrest.

From that night on, Lora was never kept out of the nursery again. She wasn’t just a good dog—she was a hero.
