if, as I have a large dog who sometimes even zerknackt wood with his teeth and grind, you quickly realize that you can not get very far with the commercial snacks, wants to employ his dog bit longer. Dogs must be on and develop to their food, which is exciting and dog has something to nibble. Compared to other products to cattle scalp the pieces are here more evenly distributed, I had from other vendors already packs with oddly shaped, almost round pieces, which then simply gulped down our dog, which he of course did not get well. The selection of pieces is ever quite good. The pieces smell as it likes a dog and act relatively non-dusty dried well, but. The amount of calories keeps within limits. I can not recommend this so!
