A pitbull launched itself from a moving vehicle and stormed into an Auckland jewellery store, injuring an employee during the incident.
Auckland Council confirmed the owner was given an infringement notice and education on dog control after the attack.
Stacey Penn says the punishment for the owner 'wasn't fair' and further consequences are needed.
"The fact that she's already been warned previously and still chose to drive around with her dog in her car - she'd been told to muzzle it and didn't muzzle it. So it's not the first time it's happened."
