I use the same bones that Cindy and Yorkidaze use. I get them from Publix (my grocery store) and they are generally in stock in the meat department. If not I can get the butcher to cut me some too. Murphy and Mia love these bones and after a good boiling they chew on them forever it seems. I have thrown them out after a few months though because they get kind of dry and nasty looking but they are so cheap I buy them for M&M all the time and just keep making them fresh ones as treats.
