If your babies are very aggressive chewers, rawhides can be very dangerous re: choking. A year or so ago, we learned that a Pet Talk member had lost her dog from choking while eating a rawhide. Some suggest soaking them in water then baking them in a slow oven to make them less gummy. I'd rather not take the chance! If you do give them rawhides, make sure you are there to supervise them! But I'm with Logan...knuckle bones are a far better, and safer choice!!
