Extraordinary dogs

Jack Russell Bingo saves his owner's life - constantly: whenever 10-year-old Cole suffers one of the life-threatening episodes in which he stops breathing, Bingo barks to alert Cole's parents. When leading fire investigator Sam, a springer spaniel, smelled accelerant on a discarded shirt it led to the arrest of an arsonist. Zoe, the water rescue team golden retriever, jumps out of helicopters to save drowning swimmers and is strong enough to pull an overturned boat to shore with the stranded fisherman still clinging on.
