Also, there is a product called orapup that will be available in the market soon...i pre-ordered one but it'll only be here in december, I'll let you know if it really works...
basically, they took the idea that in order to cure bad breath in humans not only the teeth have to be brushed, but also the TONGUE....and they are applying it to dogs. It's interesting but I'm not sure if it works....
