Grin Daily Treats do more than reward dogs with good taste and a fresh smile each day. These easy-to-digest treats contain premium natural ingredients – chlorophyll, anise, green tea, and FOS – to support your dog’s health in 3 ways: When first in the mouth, chlorophyll and anise support fresh breath and give these treats the flavor your dog will love. When chewed, the slightly tacky texture sticks to your dog's teeth, allowing the green treat to support tartar control. When swallowed, FOS* supports healthy digestion, which in turn supports fresher breath.
