Overall, this is a really sad incident.  The poor dog was just helplessly left in the car to suffer, and there's no way it could have let itself out or saved itself.  IT's really sad to me when people are this negligent about pets and other people.  Especially vulnerable populations.  Honestly I think whatever punishment she gets, such as an animal cruelty charge, is definitely deserved and she will just have to take that as it comes.  She should have been more careful with the animal, end of story.
