I think you can also push out the marrow from the marrow bones. I have several empties laying around I could mail you. Also you can find cow hooves for chewing on. Try looking at http://www.bestbullysticks.com/home/bbs/smartlist_86/made_in_the_usa.html They have an American Made section. Merrick makes bully sticks also.
