My Sadie, yep she is my puppy digger, chewer and stealer of clothes a nylabone with the nibs on it. Took her abit to use it, but when she does she seems to love it. Also bought her a kong, has no real interest in it...I was surprised as most everyone I spoke to said their pup/dog loves it. Put peanut butter in it and you won't hear or see them for hours.....WRONG!!!!! my sadie obviously doesn't like peanut butter and doesn't think much of the kong...I really was hoping as she chews other things. Oh well, gotta find different toys. Take care
