Hero dog saves owner, 81, from drowning after wheelchair rolled into lake

A hero dog saved his 81-year-old owner from drowning after his wheelchair slid into a lake.

Harry Smith was out with his beagle mix, Sarah, when his wheelchair began to slide down an embankment into the water.

He was then flipped in the chair and dumped into the water, causing Sarah, nine, to start barking loudly and splashing to attract attention.
