In my own opinion,I think Aero is smart,friendly,loving, happy and joyful.I think Aero is an smart dog because in the story,it says Aero can understand short commands like Find him!orStop him!and No barking!and when Officer Mike
puts his hand flat it means down.I think Aero is friendly because in the story,it says Aero likes children and is always jentle with them.I think Aero is loving and happy because in the story,it says Aero pushes his head agaist his partners head to let him know he needs a break.And Aero plays with a tennis ball. And lastly,I think Aero is joyful because in the story it says when Officer Mike goes to bed Aero will plop down on the floor  near the bed.He lays his head on his paws,and with a sigh he goes to sleep next to his best friend!
