The full name of the breed sounds like "Labrador Retriever", which is explained by the history of breeding of the breed. St. John's Canadian dogs mated with curly-haired retrievers and the Labrador was born. It is correct to point out that the Labrador Retriever is one of 6 officially recognized varieties of retrievers. At first, the only possible color of the dog was considered black, later fawn and chocolate were added.
