I have been using this dental kit to brush my dog's teeth for three years now. He's not too thrilled about it when I do brush them, but the product does work very well.
The kit comes with a double headed long brush, finger tip rubber brush, toothpaste, and a few breath mints. My dog is a large breed so I use the large end of the double ended tooth brush. I tried to use the rubber finger tip brush once, but because he does not like to get his teeth brushed he clamped down with my finger in his mouth. I would not suggest using the fingertip brush unless you have a small dog and you can hold their mouth open with one hand.
The toothpaste is very mild and has a slight fresh smell to it. It does a great job keeping plaque off the teeth, but if the plaque is already established hard on the tooth it will not clean it off. I have to be very careful around the gums because the brush is so stiff it makes the gums bleed a little. The toothpaste does a great job getting rid of doggie breath for a couple days. Duke liked the mints in the package also. They smelled and tasted just like human breath mints!
