St Jon Laboratories Petrodex Enzymatic Toothpaste: Available in Beef and 70 gr. Hydrogen peroxide-producing formula. Fluoride free.Dental care is just as important for your dog as it is for you. Dry food and chew toys help clean some of your pet`s teeth, but they don`t replace brushing at the gumline where most dental problems begin. Introducing your pet to brushing is not at all difficult. It only takes a few minutes a day and can add years to your pet`s life.
