Hot weather does not mix if it is with children or animals. Recently a stupid woman spent three hours at the Ontario Mills mall and left her now dead puppy in her car because she was too lazy to take it home. The dog was rescued, but it had severe heat stroke and had to be put down.
The woman who owned the car where the incident occurred will face felony animal abuse charges.
