Breath fresheners only work for a short time, they don't tackle the problem - that could be anything from teething, to a double row of teeth, to an older dog having problems with tartar. Yorkies have a serious problem with tartar, and if not taken care of, they will lose their teeth. I recommend a dental also. We use Petzlife tooth gel that is said to soften tartar and we brush with toothpaste made for dogs, Joey also chews on Bully sticks nightly and this helps clean teeth. At 4 1/2 he still has fresh smelling breath. How old is Charlie, if he's a 6 months or so, he's teething, and this causes stinky breath. If he's a year or so, it could be a double row of teeth, meaning baby teeth didn't come out, and food builds up between the rows. If he's two or more, it's likely tartar and if bad enough gum pockets fill up with food, and this stinks.
