Thoughts?

This was posted in a group I am apart of on Facebook. This puppy was apparently stolen out of the owners car while they were shopping inside the mall. They are people upset that they left it in the car in the first place and others defending them saying it is fine because it wasn't even hot out (the day this happened it was 74° outside and very sunny). What are your thoughts? Were they wrong for leaving the dog in the car or was it okay if they weren't in there for long?
