These Origins are 100% natura dog chews hand crafted from a tuber root. Each one is individual and they can satisfy your dog's urge to chew. They are eco sustainable and will not splinter, they are also full of nutrients, obviously low in fat and can help keep your dog's teetch clean. They last for ages and we give them for a while and then take them away so they are freshly rediscovered! They are also suitable for puppies.
