This is by far the best dog toy we have ever bought. We have a black lab about 1 yrs,he chews everything, including Kong toys, it takes him awhile but still he can chew it up in a day. We bought him this product and its been a year and he still hasn't chew it up, a small piece off each end but considering what is on the market today , this is BY FAR THE BEST and TOUGHEST chew toy out there, excluding the new deer horn toys which cost an arm and leg. Great Job guys keep up the good work and if you are considering buying this product, all i can say is it is the best investment you can get your dog period.
