For our dog we bought this croissant. It immediately what his everything! The Quietschfunktion are the not too annoying sounds of itself for us it was fine too. Full five stars I would have given for a lifetime of six months. In our bullies the poor little creature has lost the first limb after four months. Would not have thought that it's so long. So be careful that he does not rumkaut it already extended the pleasure of a lot! For a toy made of organic materials, it has maintained long! Buy recommendation!
