Logic Oral Hygiene Gel can be used as a toothpaste or even added to food. It is intended for use in dogs and cats and is most effective if applied with a soft brush and applied gently over the surface of the teeth, paying particular attention to the junction between the tooth and the gum. In some pets this can be very difficult and Logic Gel benefits dogs and cats if just placed in the mouth, or even added to food. The simple action of the tongue and cheeks will tend to distribute it over the surface of the teeth. It contains enzymes and a mild abrasive which help to break down plaque and along with the action of chewing, the teeth can be left cleaner. Most animals enjoy the taste and happily accept it being placed in the mouth. Ideally it should be used every day.
