It is actually one of the many nicknames given to a conformation-type Labrador Retriever. There are 2 different lines of Labs bred in this country: performance/field (AKA American) type which are rangy, finer boned with longer, narrower heads bred to have high energy %26 drive for use in retrieving/hunting.
