Blue is not a boastful dog. He doesn't think he is the king of the world, even though it might look like it in this photo. Blue is playful, has a lot of personality, and gets along well in modern society. But he also retains some of the characteristics of his ancestors. He is a sheep dog at heart, and he likes to shepherd his herd. That includes protecting his herd from any threats, such as teenagers riding bikes, or people wearing certain types of shoes. He is a good shepherd.
