Thinkers Duck are small but hearty, meat-packed sticks with added EPA and DHA to support healthy brain function. Made with real duck as the 1st ingredient, these treats are made with limited ingredients, are naturally preserved and contain no artificial flavors, corn, wheat, or soy. Mini Thinkers offer chewing satisfaction in smaller portions and are size-appropriate for smaller dogs. And we take the extra time to air-dry them in batches in our USA facility instead of baking them in order to retain more of the ingredients inherent nutrients (but your dog will just think that they smell and taste amazing).
