"Cows run away from the storm while the buffalo charges towards it." - Wilma Mankiller. A meal topper straight out of the wild wild west. Buffalo, baby. Buffalo is a novel protein for many pets, making it a hypoallergenic choice and perfect for allergy prone doggos. Buffalo is low in fat and high in iron, protein, zinc and vitamins B6, B3 and B12. Liver is an excellent source of the mineral copper and vitamin A. Freeze dried liver is ideal for pets who don't enjoy the texture of fresh liver.
