Bacteria and food particles cause plaque to form on teeth, causing tooth and gum decay, leading to bad breath. This product contains enzymes that fight harmful bacteria and reduce the formation of plaque. This easy to use product complements dogs and cats' regular dental care regime. As pets drink throughout the day, they will benefit from this oral hygiene method all day long.
