My own opinion is that Aero is smart also talented because  he works with his powerful nose. In the story ,it says Aero can  find lost  things and lost people. Thats  why its called powerful noses. Aero is active too. In the story, it said when Aero is ready for his break, Aero lets officer Mike know .So Officer Mike know so he can pull over at the park. Also in the story it says Aero can understand sign language when  officer mike does . When officer mike puts his hand out flat it means down.
