When new parents Jeff and Danielle Livak brought their daughter Melina home from the hospital, they weren't sure how their boxer Bella might react.
"Would she be jealous? Protective? We knew she would be a great family dog but we didn't expect this!" they write in the video description.
The parents were surprised to find that Bella would not only protectively sleep under Melina's crib, but that she would join in when the baby cried to whine along until Melina stopped.
Though this video was originally uploaded in 2012, it is just now making rounds on the Internet, racking up hundreds of thousands of views.
