Bad breath        My one yorkie, Bengie has damaged teeth that I brush daily, his BYB gave him a very strong antibiotic when he was just a pup and it discolored the enamel on his teeth.  They look awful, but the vet says it is just cosmetic.  However, his breath is AWFUL!  I have tried just about every product on the market and nothing is working.  Greenies, denta bones, breath freshener, you name it, I have bought it.  Any suggestions, I love my boy, but sometimes his breath just knocks me over.  It cannot be the food, cause my other boy does not have this problem, just Benni.     |
