I think Aero is smart, nice, and a friendly dog .

I think that Aero is smart because details from the story say "officer Mike sits in the drivers seat but Aero will not let anyone else sit in the front until officer Mike says it is ok .

I also think Aero is nice because details from the story tell me Aero likes children and is always gentle with them .

I think Aero is active because he does things like finding lost children and lost things. That shows that Aero is nice ,smart and friendly.
