Description Source Story: 100% Australian beef trachea – low temperature dehydrated on our Bannockburn farm. In keeping with the nose-to-tail philosophy, using organs, bones and other parts as dog treats and chews , this ensures that ‘nothing is wasted, and everything is celebrated’. Feeding Guide: These Moo Tubes are pretty stinky, which makes dogs love them even more!  These are outstanding for making enrichment treats by stuffing them with other goodies and freezing. Great for slowing down those hungry hounds or giving a cool treat during warmer weather. To start, we recommend breaking the tubes into smaller chunks. This is because the trachea is an oily organ – which means it can cause upset tummies if too much is fed too soon.
