Description Source Story: Sustainably sourced, wild caught Australian Gummy Shark (known as flake).  Gummy Sharks are very common and declared ‘least concern’ by the International Union for the Conservation of Nature. Furthermore, the parts we use are left over from human consumption and may otherwise be discarded. The fish is processed by low temperature dehydrating in a factory in North Queensland and because of the low temperature drying method, the nutrients and Omega oils are retained. 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: One of these twists lasted our medium/large dog about 2 hours of playful, satisfied chewing. Be warned they’re a bit stinky so best fed outside.
