BETHESDA, MD — Two heroic dogs give a new meaning to "man's best friend" after saving their owner from knee-deep mud.

The 87-year-old man got stuck in the mud while walking his two dog at the edge of the Potomac River, according to multiple media outlets. When he couldn't get out, his dogs went to the C&O Canal towpath, located about 50 yards away, and alerted two passing cyclists.

The cyclists then found the trapped man and called 911.
