If you have a chewer and are afraid of bones splintering/chipping give antlers a try, they are supposed to be the safer alternative. You can even get moose (although deer and elk is recommended).
Try a google search: "antler dog chews moose"
Best prices I have found on them so far is ebay, I never see them being sold in the pet stores, just online. My puppies love them and they last awhile (longer than Nylabones), don't smell, or stain. Here is a link to some general info about antler chews:

On Ebay I have been getting the large 8" pieces for about $4.95 each (plus shipping) my dogs have them down to about 4" now after a month.
