I brush all my dogs teeth daily.  Teddy has very clean teeth with no tartar but he is going to have a dental procedure to get under the gums and do X-rays, along w/ a biopsy of a mass in his mouth.   My dogs used CET vanilla mint as well, but since that product became difficult to locate recently, a friend told me about another product and I happen to like it much better.  My dogs like the taste and I think it freshens them up nicely.  It's called Arm and Hammer clinical care vanilla ginger dog toothpaste and I purchased it online on Petsmart.  I like the container it is in too.
