It's a costly lesson that was learned by a police officer who left his dog in a patrol car on a hot day in Alabama.
The three-year-old dog named Mason was left inside an officer's car on Thursday, June 18, while he was attending a hurricane preparation conference in the town of Gulf Shores.
Mason's handler Corporal Josh Coleman forgot that Mason was still in the back seat of his patrol car. On realising Mason was absent, Coleman then located him in the vehicle.
