The Landseer is a dog that originated in Canada. It is a black-and-white variety of the Newfoundland that is recognised as an independent breed in continental Europe.

The Newfoundland is a large breed of working dog. They can be black, grey, brown, or black and white. However, in the Dominion of Newfoundland, before it became part of the confederation of Canada, only black and Landseer (white-and-black) coloured dogs were considered to be proper members of the breed. They were originally bred and used as working dogs for fishermen in Newfoundland.
