A couple things I was thinking…

Has your pup had a checkup with blood work recently? Bad breath could also be indicative of some medical issues.

Also, I once recall Sandy mentioning that she used this product with success: http://www.amazon.com/gp/product/B0047VWPNI/ref=ox_sc_sfl_title_9?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

Mine eat a variety of foods including raw and raw meaty bones and fortunately, neither has bad breath.
