Bilbo the Dog is a Newfoundland who works on Cornish beach of Sennen, helping swimmers who get into difficulty and making sure people stay away from dangerous currents. Tourist Lein Snippe was threatening to go swimming in a deceptively dangerous stretch of water when Bilbo came to the rescue, swimming in front of her and doing his best to keep her out of the water. "Basically he was telling me 'don't do it'," the BBC reports Ms Snippe as saying.
Newfoundlands like Bilbo apparently have a natural talent for rescue work. Bilbo works as part of a team with a number of humans.
Bilbo advises visitors to Sennen to always swim between the flags.
