For my two dogs (5kg and 10kg) really a good mix. They are small, thick and thin pieces mixed colors. So I can adjust my needs the good snacks. The smaller dog gets eg a thinner piece, than the larger, so that they are ready at the same time somewhat. Or is there even a thick cartilage if they are to be employed longer and just a little bit in between. The forms vary widely from thin rod until thick cartilage and there are also some real Fitzelstücke there, where I always have some fear that they will be swallowed without chewing.
For me, the pieces are so variable and therefore cheaper to use than the usual 10cm pieces. The trend I would also say that these snacks are more suitable for smaller up to medium dogs.
