Description Source Story: Low temperature dehydrated beef tendon sourced from the amazing guys at Provenir – the processors of the highest welfare beef in Australia. 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’. Sizing/Feeding Guide: Tendon Chews range between 25-30cms but are all different shapes and sizes. A 25cm chew lasted our medium/large dog 25 mins of enthusiastic, voracious chewing. I broke one up into thirds for our small dog and it lasted her over an hour (FYI, breaking them up requires a fair bit of elbow grease ��)
