They are exceptionally affable, gentle, intelligent, energetic, and good-natured, and Labradors are generally considered good companions for people of all ages (due to a high level of patience and tolerance for children), making them both excellent companions and working dogs. With training, the Labrador is one of the most dependable, obedient, and multitalented breeds in the world.
