I want to thank you so much for making the first toy my 1 1/2 year old German Shepherd, Whoopy, hasn't destroyed. She has eaten so many "durable toys" and reguritated them weeks later in multiple 1-1/2 inch chunks. Your Hurley Bone is the ONLY toy that I have found that is safe for her to play with. She has constantly played with, chewed on and retreived this bone for more than 3 months now without any wear and tear.
