We set out to make Tender and True better from the ground up, with no compromises and the certifications to prove it. These grain-free treats contain bison that have been certified by the National Bison Association. This group has been working diligently to restore herd numbers for the preservation and restoration of the grasslands in which they reside. These single-source protein treats are a perfect snack for even the pickiest of dogs. Contains no artificial preservatives, colors or flavors
