A narrow channel created by one or more channel walls. The channel is engineered with narrow dimensions so as to carry out its function of supporting small bags filled with waste. The channel may be formed as a single body, attached to another body, or formed or incorporated into another body or device, such as, but not limited to, animal leashes, retractable animal leashes, pet waste bag dispensers, pet harnesses, and pooper scoopers. Bags containing animal waste may be inserted into the channel. The bags may be supported by the channel. Additional small bodies including but not limited to rings or cord loops may be inserted into and supported by the channel.
