In my own opinion, I think Aero is a smart dog because he knows when not and when to. Also I think Aero is a very playful dog because everytime when Officer Mike lets him have a break Aero goes straight to the tennis ball so Officer Mike and Aero can play with it. I think Aero likes having breaks so he can play whatever he wants for a while before he has to get back to work. I think Officer Mike likes having a police dog like Aero because Aero is smart, intelligent, knows when and when not to play. Aero is a kind of dog that will find lost children ,that's why Aero is a special dog in my own opinon!!!!!
