Baby Monitor Catches Sweet Dog Checking On His Little Sister Every Night

"It was like he knew he had a job to do and it was to watch out for her."

This is Berkley — a big fluffy dog with an even bigger heart.

And it shows.

Berkley lives with owner Christine Jo Miller, her husband and their young daughter, Elainey.

At first, when Elainey was still a baby, Miller was a little worried that hefty Berkley's goofy energy would be a bit too much for her daughter to handle. However, Berkley and Elainey soon fell in love.

"I used to have very far boundaries for him with her, since he’s so big," Miller told The Dodo. "But the only thing that would make her happy was him being in the room. So once we gave him the OK to be around her ... [we] realized how gentle he really is."

When Elainey was about 8 months old, the Millers set up multiple baby monitors in her room to keep better tabs on her as she slept. They quickly came to realize they weren't the only ones.

After reviewing the footage, the Millers saw Berkley checking on Elainey, too.

"We caught him the second we got the cameras," Miller said. "It was like he knew he had a job to do and it was to watch out for her."

Elainey's parents are always be close by, of course, in case Berkley disturbed her sleep. But his goal with the visits seemed just to ensure that all was peaceful and well.

"He’s never gone in to do anything crazy," Miller said. "[He] just checks in and turns around and leaves, so I know it’s his duty to do as part of the family."

Now that Elainey is old enough to understand, she's come to appreciate having such a friendly pup watching out her.

"I told her he checks on her to keep her safe at night," Miller said. "She just smiled and said, 'Awwwww.'"

Elainey is now 5 years old, and a big sister. Her beloved dog, Berkley, remains by her side to this day.

"[Their friendship is] still flourishing!" Miller said. "We live on 30 acres now and he follows her and her brothers everywhere they go. He's as protective as ever. He loves all his babies a ton!"
