Labradors were first used to retrieve large fish escaping from nets in the icy waters of the North Atlantic off Newfoundland. They were also successfully utilised as retrievers of waterfowl. When fishing boats brought their catches to English ports last century, the strength and fearlessness of these water dogs was soon recognised by the local sporting gentry, who promptly set their gamekeepers to breeding them. As a result, the Labrador Retriever we know today is very much a British breed.
Being a gundog, and therefore used to spending a great deal of time with his master, the Labrador exhibits a tremendous preference for the company of people. He is usually an ideal children's playmate and family pet. The best possible reference for the breed's docile and reliable nature is the fact that virtually all guide dogs for the blind in Australia are Labrador Retrievers.
The Labrador is very responsive to training and requires regular exercise.
