I agree with Mom - I stay away from this stuff, it makes me nervous. Colt is the strongest chewer I have ever seen. He shreds those rope toys and downs a greenie in a split second. Occasionally, I get a sterilized bone filled with something. I pretty much stick to Kongs or biscuit type treats. If I get the really big ones, they keep him busy for awhile if he's interested - sometimes he's not. Frankly, I think I should just offer up my Pottery Barn rug to him as sort of a sacrificial offering - is that expensive enough for a "Prince Prissy Pants"? He has champagne taste and a beer drinkers wallet when it comes to chewing stuff up....
