I feel for the ones of you that have them over a year and still chewing, I guess I have been very fortunate. the only things mine chew on are their chew bones. My sons 2 also were done right around a year or maybe 13 or 14 mos. they will be 2 in July and it's been awhile since I've seen his chewing too. I probably have 20 chewies down on the floor though |
