Trent Cowan is being credited with rescuing a dog that had become trapped in an underground drainage ditch, according to a video report from 4029tv. The incident occurred on Wednesday, when the sergeant rappelled into the manhole to retrieve the dog stuck in the storm drain. Video of the rescue shows Cowan descending through the manhole opening to reach the dog, as is often standard procedure in such situations. Cowan brought the dog, described in the report as a puppy, named Dolly, back up through the manhole.
