USA CHICKEN BARZ BAG 8 OZ Made in the USA 100% Chicken Barz. Our Chicken Barz are 100% natural and made for the finest quality chicken. We grind the chicken breast and form it into to a bar shape that makes it easy to break into smaller pieces which are great for small dogs. They also have a softer texture than our Chicken Breast Strips which make them the perfect treat for older dogs. 100% natural, low in fat and high in protein... what could be better!
