A system for preventing animal suffocation because of a bag is disclosed. The system includes an attachment for the bag having a first panel and a second panel. A hinge element attaches the first panel with the second panel. The first panel is configured to attach to a first outward facing portion of the bag and the second panel and is configured to attach to a second outward facing portion of the bag. A one-way air flow valve is integral with at least one of the first panel and the second panel and is configured to allow air to flow from an outside environment into the bag only when an inward force acts on the valve and pulls air from outside the bag inward inside the bag.
