In my own opinion Ithink Aero is understanding because when his partner yells stop, he lays down, when his hand is  up, he stands, when his hand is flat he sits and he gives  him a belly rub that is my first opinion. I also think he is joyful,  he is joyful because in the story, it says he is filled with energy. And I think he is very special to Officer Mike. Lastly, I think he is friendly  because in the story it says he did not bite anyone in the classroom visit and he is smart . This shows that he is calm and also very smart. This reminds me of the time my dad told me to take out the trash and I obeyed just like Aero in  the story.
