We suggest when first introducing your horse to a new hay bag or net, please pull some hay through the openings to guide your horse where to begin eating so as to avoid your horse nibbling the bag or net. It is not recommended to leave an empty hay bag in your horses stall for any extended period of time. This is not only hazardous, but also may result in your horse treating this product as a toy and destroying your investment. This is the best constructed slow feed bag in the USA! For use in the stable, on a trailer, or at a show; this durable and rugged slow feed bag is a lasting value.
