I think C.E.T. Aquadent is a trademark. On the water additive, be sure and follow the directions as there is xyltol in it. It isn't dangerous but you need so little, it can be problematic if your pup has blood sugar problems if over used.
Emma has been using it since she was a puppy and she is 4 1/2 yrs old with great teeth! My vet said most dogs need dental cleaning by the time they are a year old. Emma still doesn't require it so I am very pleased.
