Our dog finds the Geweihkaustangen excellent, I do less. The statement "does not splinter" is to be treated with extreme caution. Certainly the antler is a natural product and is meant to be nibbled, questionable, however, that in some of Geweistangen after just one bite the outer shell with sharp edges chipped and thus there is an increased risk of injury to the dog. My recommendation: Good for dental care, but by no means leave the dog alone with it! It is important above all to choose the right size for the dog.
