Our 3 year old Boxer, Luna, can rip, shred and destroy almost anything. I was hesitant to buy this toy for her because it was $18 at a local pet boutique ... but it is worth every penny. Luna LOVES it, she spends hours chewing it but hasn't made a dent in it. It's perfect because it's not so hard that she doesn't get chewing satisfaction but it's tough so there aren't pieces of it everywhere (or for her to choke on!)
Really pleased, will buy more, highly recommend! :)
