LEWISTON — A Lewiston police department dog is being credited with finding an 82-year-old Alzheimer’s patient.

The dog named Ailos followed a mile-long scent Wednesday and found the man lying in the grass next to a snowmobile trail.

He was treated for hypothermia and returned to his home.

The Sun Journal reports that the search began at about 5 a.m. when a woman called police to report that her father had wandered off during the night.

Ailos was able to pick up the missing man’s scent near his home.

The track brought the searchers to a snowmobile trail off Sabattus Street. The missing man was found in the grass about 250 feet from the road.
