Support dog recognizes panic attacks in owner

A dog's owner has trained him to watch for her impending panic attacks by noticing shifts in her behavior.

Amber Oliver, a Massachusetts-based certified professional dog trainer, taught her dog Oakley, who is five years old, to notice changes in her body temperature, respiration, and heart rate and tell her that she might be about to experience a panic attack.

The task-trained service dog is shown calming his owner by stroking against her legs in the video, which was shot at Cincinnati and Northern Kentucky International Airport.
