Two Sisters Bakery has introduced its line of all-natural and organic cookies for dogs. The treats are made in a certified human food facility in Texas and do not contain wheat, corn, soy, dairy, yeast or by-products. The treats are also free of artificial preservatives, colors and flavors. The company uses natural, wholesome ingredients like natural peanut butter, organic oats, organic barley, organic flaxseed, apples and bananas. Two Sisters Bakery treats come in two flavors: Nutty Buddies, which are natural peanut butter cookies, and Sweeties Rewards, which are sweet potato and cranberry cookies.
