Green Beef Tripe may be the smelliest pet chew we make, but it is certainly a favorite! Our beef tripe is cleaned with water, soaked in water, cut into strips and dehydrated for approximately 24 hours. We do not use any bleach in making these pet chews. We do package the green beef tripe in resealable bags to help reduce the smell. You'll thank us on this one! Each bag is 6 ounces and contains approximately 6 - 8 pieces.
