When you welcome a new bundle of joy in your life and home, you expect your life to be completely flipped upside down, but you usually think the biggest challenge of all would be the lack of sleep. For a couple who became parents for the first time, the biggest challenge came from their Golden Retriever, Laura.

The moment the baby was brought home, Laura turned into a full time nanny, and that wouldn’t be a bad thing if her behavior didn’t become worrying to the parents.

Well, the parents did expect the dog to be loving and protective, but to them, it felt like Laura’s protective instinct crossed over into behavior that was sort of bizarre, and honestly, even a little unsettling, too.

Everything began within the first month after the baby came home. For an entire week, the parents had witnessed a trend emerging. No matter what, every single night, right when it got dark in the house, Laura would walk to the baby’s crib and simply stand there like a living statue. She didn’t settle down on the floor, fall asleep, or even walk to the kitchen to have some water from her bowl. Instead, she stood upright, starring through the wooden bars of the crib, sometimes emitting whining noises.

Initially, they brushed their worries aside and tried to convince themselves that Laura was just adorable and loved the baby too much.

However, after several days passed by, it became anything but that. The dog’s nocturnal routine became very disturbing. She would wait until the sun rose while the parents slept in their room. The most puzzling part about the situation was that during the day, Laura would behave just like any other pet. She would eat, play with her toys, rest on the couch, and nothing seemed to worry her. It was only after the night came that Laura started acting strange.

“What’s going on?” the mom asked her husband one night, “I’m starting to be seriously scared here. What if something’s wrong? Do we need to take her to a veterinarian?”

In an attempt to find out why their dog behaved so strangely, they finally decided to put a night vision video camera to see what was really going on during the night.

The next day, they woke up, had their coffee, and checked the footage. What met their eyes almost immediately caused the blood to freeze in their veins. They realized in a split second that their baby girl hadn’t just been in danger; she had been targeted.

They noticed from the footage that the baby’s room stayed completely still until precisely 3:12 a.m. Suddenly, out of nowhere, the dog stood up and got ready for action, her ears flattened and her back straightened, as she started growling furiously at the baby’s room’s window. The scene that then unfolded on their phone was truly horrifying to see; the window frame slid up on its own. Someone must have pushed it from the outside to gain access. Next, a gloved hand appeared trying to rip the screen to shreds.

Without losing a second, Laura leapt into action, rushed at full speed towards the window, tore the curtains open with her teeth and jumped directly on the windowsill, barking as loud as never before.

In just a second, the hand disappeared back into the darkness.

The mom didn’t wait for the video to end before she called 911.

As the detectives arrived on the scene to gather evidence, pieces of the puzzle started to fall into place. Apparently, a series of burglaries had plagued the small town over the past month where the burglar had broken into the houses of residents using the ground floor windows. Even worse, the police realized he was intentionally targeting homes with newborns. He knew the parents would be utterly exhausted, deeply asleep, and highly vulnerable in the middle of the night.

But he didn’t succeed. After two days of searching for the burglar, the police managed to locate and arrest him. In addition to discovering small pieces of material from a heavy glove and traces of fresh blood, investigators uncovered new facts: during Laura’s desperate lunge toward the window, she had actually managed to bite him before he escaped.

From that terrifying night onward, the couple completely changed the house rules. They never locked Laura out of the bedrooms or left her in the kitchen at night again. Instead, she earned a permanent spot right in the center of the nursery, sleeping peacefully curled up next to the crib.

And the strange, anxious whimpering? It stopped completely. Laura didn’t need to pace or whine anymore. The threat was gone, the house was safe, and she had officially done her job.
