The Golden Retriever is a breed of dog, historically developed as a gundog to retrieve shot waterfowl and upland game during hunting. As such they were bred to have a soft mouth to retrieve game undamaged and an instinctive love of water. Their intelligence and versatility sees them employed in a variety of roles including illegal drug detection, search and rescue, as hunting dogs and as guide dogs. Its friendly, eager-to-please and patient demeanour has also made it one of the most popular family pets.
