From ABC News in Kentucky:

The parents of 7-month-old Finn Jordan suspected something was wrong last year when their dog began to growl and snarl at the babysitter, Alexis Khan, 22.

“We noticed the dog was getting very defensive when Alexis was around. He would growl and stand between her and our son. His hair would stand up on the back of his neck and we knew something was up,” Benjamin Jordan said.

The parents stashed an iPhone under a cushion to get a recording, expecting to hear the babysitter mistreating their dog. Instead they heard her swearing at the baby, along with the sounds of slapping and shaking. Police weren’t sure it would be enough for a conviction, but the babysitter confessed when interrogated and was sentenced to 3 years, the maximum, and had her name put on a list of child abusers to prevent her from ever working with children again.

Thankfully the little boy, who the parents rushed to a hospital right away, checked out just fine.

Good dog.
