I know of a dog who saved her owners from a house fire. She was deathly afraid of stairs. She absolutely refused to go upstairs in all the years they had her. One night they had a bad chimney fire and the dog overcame her fear of the stairs and went upstairs and woke them up. She saved their lives! Less than 6 monthes later, they had her put down because she shed a lot and she was a white long hair Spitz Husky mix and they got tired of bathing and brushing her. Disgusting!
Disgusting is too kind a word for it.
