Redbarn Lamb Lung Filets are made from a single ingredient: lamb lung sourced from grass-fed, free-range animals raised in the USA and New Zealand. The lungs are oven-roasted into a crunchy, jerky-style filet that delivers a meaty flavor dogs find highly palatable. Because the recipe contains no wheat, corn, soy, grains, or gluten, and no artificial colors, flavors, or preservatives, it suits dogs with food sensitivities as well as everyday snackers. The crunchy texture also helps scrape away plaque and massage gums as a dog chews. Pieces can be broken down for training rewards or offered whole as a daily treat. Owners should monitor dogs while feeding and provide fresh water alongside any treat.
