Thinkers Chicken are hearty, meat-packed sticks with added EPA and DHA to support healthy brain function.  Made with real chicken as the 1st ingredient, these treats are made with limited ingredients, are naturally preserved, and contain no artificial flavors, corn, wheat, or soy.  Because of their large size, Thinkers offer substantial chewing satisfaction or can be broken into smaller pieces to create multiple treats. Thinkers also come in Salmon, Duck and Lamb.
