Personally I don't think you did anything wrong, but that's me..
I take Neva just about everywhere I go.. Work everyday, where she gets to sit in a little 10 x 10 office for 8 hours.. If I go see customers then she goes in the car with me and I just leave the truck running with the AC on. I've never had a problem with it so far.. I typically check on the truck though if things are taking longer then expected.
