Back in 2013, a family dog became a hero when he alerted Mom and Dad that the baby was being abused by the babysitter. How did the pup, named Killian, manage to do this? Killian is normally a very mellow and peaceful dog, so his owners were alarmed when suddenly he became very aggressive towards the babysitter. Every time the sitter was around, Killian would bark and make a huge commotion.

This change in the dog's behavior led the parents to act. They set up recording devices around the house, and quickly discovered that the nanny was being abusive towards their child. Luckily, they were able to press charges before any real harm could be done. Good job, Killian!
