Nineteen-year-old Brittany Wiebe pleaded guilty Monday in Edmonton provincial court to one count of causing an animal to be in distress.
Crown prosecutor Christian Lim says security staff noticed the puppy, named Franklin, in obvious distress locked away in the vehicle.
As temperatures reached 33 C outside that day last August, Wiebe was inside with friends at the mall's water park.
Wiebe's lawyer says his client's actions weren't malicious, but she didn't understand the dangers, and the judge agreed.
The woman has also been banned from owning animals for 10 years but is allowed to keep Franklin. (CHNL)
