The Labrador retriever (or lab) is a type of gun dog.  They are normally even- tempered and well-behaved around young children and the elderly.  

Labradors originated on the island of Newfoundland.  The founding breed of the Labrador was the Saint John's water dog.  

Labradors are famous for being guard dogs for the blind.  Some famous people like Bill Clinton owned Labradors.
