Thinkers Salmon are hearty, meat-packed sticks with added EPA and DHA to support healthy brain function, are a natural source of Omega 3 & 6 fatty acids, and support skin and coat health. Made with real salmon 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 Chicken, Duck and Lamb.
