4dogs chews are natural and healthy treats for all breeds of dogs. Each dog chew has been produced by hand from the naturally discarded antlers found in Polish forests each spring, from red deer, fallow deer and elk living in the wild. Dog chews are produced without any artificial additives, and are rich in collagen, protein, calcium, sodium, phosphorus, magnesium, iron and potassium. Perfect for all breeds of dogs of any age, irrespective of size, except for puppies and old dogs. All antlers used for the production of our natural dog chews are subject to rigorous selection based on their quality. We select only the best quality pieces. The antlers are also sterilised by hot steam.
