Bone is a hit for our 7 mo springador puppy (about 21kg) and it has definitely saved our skirting board from being chewed!
The honeycomb is safe for the dog because it crumbles, but that also means its a bit messey, so we try to have him accept his chew on a mat, but he will carry it around with him! very cute! It has no odour which means its a great hit when we are trying to eat our dinner and keeping the little guy busy, but he does lose interest in it and resumes interest in our tea... anyway work in progress; highly recommended and its worth the cost given how long it lasts for.
