Jack started having bad breath and the vet said his teeth were fine - just a small build up of plaque but not enough to have a dental done. I started using the CET poultry flavored toothpaste on him and within a couple of weeks his bad breath is gone. Make sure you get way in the back of your pups mouth. Here is the toothpaste I use oh and I also give them a Dentastix, one every other day or so.
