Thinkers Lamb are hearty, meat-packed sticks with added EPA and DHA to support healthy brain function. Made with real New Zealand lamb 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. And we take the extra time to air-dry them in batches in our USA facility instead of baking them in order to avoid high temperature processing (but your dog will just think that they smell and taste amazing). It takes longer, but we think its worth it.
