8in1 Delights Chicken Bones Strong M are made of tasty beefhide and delicious chicken breast and ensure strong, long-lasting chewing fun for medium-sized dogs with a weight between 10 and 25kg. Due to their firm consistency the bones offer an extra tough chewy treat and therefore perfectly fit for dogs with a particularly strong instinct to chew. More than this: while keeping your dog busy, the bones enhance dental care. Due to the natural abrasive action of chewing, tartar is removed from your dog's teeth and in that way the bones support your dog's dental health. The low in fat 8in1 Delights Chicken Bones Strong M perfectly serve as a mouth-watering chew to reward your dog. They are rich in proteins and free from artificial colours and flavour enhancers. Furthermore, neither GMO's nor gluten are added to the oven baked chews.
