Patricia Adshead was in the kitchen with her dog Oi when a machette gang broke into the house.
As the gang members got closer to Patricia, her dog fearlessly attacked them and bit one of them on the hand. Even when another gang member pulled out a gun ready to shoot Patricia, Oi jumped right at him and eventually kicked all the men out of the house. He saved the woman’s life.

Yang Yun was a very experienced diver. While attending a diving competition, however, her legs paralyzed completely and she was unable to swim back to the surface.
When Mila, a Beluga whale, sensed the diver’s panic, she used her nose to guide her back to the surface.
