Protective dog

A protective pooch is being credited with alerting a South Carolina family that their babysitter was abusing their 7-month-old son.
Benjamin and Hope Jordan, of Charleston, first grew suspicious of Khan after their dog began acting aggressively towards her.
"About five months into her being our baby sitter, we started to notice that our dog was very protective of our son when she would come in the door.  He was very aggressive towards her and a few times we actually had to physically restrain him from going for her."
Suspecting something was up, the couple placed an iPhone under a couch to record Khan's day with their son, Finn, while they were at work.
Jordan said the device caught Kahn cursing and hitting the child.  On the recording slapping noises and crying is heard, both distress crying and pain crying. 
Kahn, the babysitter was arrested and later confessed.
The dog’s, a mixed breed, name is Killian which is the anglicized version of the Irish name Cillian which means “war” or “strife”.
So there!
