A golden retriever is a type of dog known for its friendly and intelligent nature. Originating in Scotland in the late 19th century, this breed was developed to retrieve game from water and land due to its strong swimming ability and excellent sense of smell. Golden retrievers are characterized by their dense, water-repellent coat, which is usually golden in color. They are highly trainable and often serve as service and therapy dogs due to their gentle temperament and loyalty. Their sociable nature makes them great family pets, as they typically get along well with children and other animals.
