New Nothin’ to Hide® Ultra Premium Injection Molded Dog Chews from Fieldcrest Farms offers a longer lasting, safer and more digestible chewing experience for dogs. Nothin’ to Hide® Ultra offers the same collagen formula as our original Nothin’ to Hide® chews but now more dense. Injection molding condenses the material at a high pressure to eliminate air bubbles and create an ultra, long-lasting chew. Designed for more aggressive, heavy chewers, Nothin’ to Hide® Ultra lasts 3 to 4 times longer than our original chews! And, Nothin to Hide ® Ultra is all natural, low in fat and calories, high in protein, flavor packed, gluten free and highly digestible. Nothin to Hide® Ultra is available in a variety of shapes and sizes in delectable beef flavor!
