In itself, I can not fault report to the product. The dogs love it, it lasts a long time (about 3 months) and the idea of a 'renewable resource' makes me happy. However, we were very disappointed when it arrived with us. We did not get such a piece as the picture shows it. Not even close! Our antler piece reminds me more of a block of wood and has the dimensions 5cmx8cm, making it very compact. Our dogs it could therefore not hold good between the paws while chewing it.
