Formulated specifically for dogs. Does not foam - no need to rinse. Helps clean teeth and fights bad breath. Specially flavored to assure acceptance. Fluoride free. Dental care is as important for your dog as it is for you. Dry food and chew toys help clean some of your pets teeth, but they dont replace brushing at thte gumline where most dental problems begin. Introducing your pet to brushing is not difficult. It only takes a few minutes a day. Fortunately, the outside surface of the teeth need the most attention and can be easily reached.
