Well, I won't write a negative review of this Nylabone Dura Chew Original Flavored Dental chew - but I haven't seen it since I gave it to him several days ago.....  so either he loves it and is saving it and trying to keep it away from the cat, or he doesn't want it in his mouth.  I'll have to update when I find out.  For right now, its hidden somewhere in a very large house..... Hmmm
