White knotted heat-shrink dog bone. Made of cow' s skin, high in protein and free of colouring and flavouring agents. Tasty but balanced for our dog's diet, its chewing helps reduce plaque and tartar and strengthens the muscles of the jaw, teeth and gums. In addition, being very durable, it also acts as a stress-reliever for our animal, particularly during moments of solitude. (EN)
