The breed is derived from the Irish Red and White Setter and an unknown solid red coloured dog. It was a clearly identifiable type in the 18th century. 

The Wheaten is probably the oldest of the four breeds. Its existence for at least 200 years can be inferred from textual references to "soft-coated" dogs. 

The Heeler is an intelligent, eager-to-please fellow, with a love of people; he enjoys being with children because he likes joining in games. 

NOTE: LANDSEER ECT is not the same breed of dog as the black and white 'Landseer' Newfoundland

Newfoundland - Landseer History

Newfoundland, Landseer or both? Actually, there are 3 versions: The American Newfoundland Landseer, the European Newfoundland Landseer and the European Landseer ECT.

The USA (AKC) recognizes both European and American Newfoundland Landseers but does not recognize the 3rd version, the Landseer ECT, as a version of the Newfoundland or even as a breed.

The Newfoundland Club of America addresses the question: "What is an ECT?

ECT stands for "European Continental Type". ECT's or Landseer ECT's as they are sometimes called, resemble Landseers, but are different in type and temperament. An ECT is a little taller, a little less broad, and to the person familiar with Newfs, just looks "different" than a Newf. ECT's tend to have a more "active" personality, and require an owner ready to live with a large dog which is more assertive than a typical Newf."

"As of 1998, Every country except the U.S. and Canada recognize the ECT as a separate breed from the Newfoundland."
