Introducing the Nylabone Chicken Flavoured Dura Chew flavour impregnated bone, which is tasty to the core. Vet approved, and a best-selling line in the USA, this product could not come any better recommended. Nylabone is made from pure virgin nylon which is annealed after moulding, resulting in a therapeutic chew device which is strong, safe and very durable and is the only product to have the flavour mixed into the material used to produce the bone. The bristle-like projections that are raised on the surface of the bone as it is chewed massage the surface of the teeth and gums and help to prevent plaque from forming. Choose the largest size your dog can comfortably hold in his mouth in order to derive the greatest dental benefit. Suitable for dogs up to 35lbs/15kg.
