Our 12 Inch Bully Sticks keep dogs mentally stimulated while treating them to a boost in high-quality protein. A positive outlet for your dog’s chewing instinct (a way to relieve stress and excess energy). Bully sticks are fully digestible and remove plaque as your dog chews. They are also a rich source of amino acids for better brain health, stronger muscles, and joint support. Great for a shiny coat, too. Best for medium chewers. Natural Farm Bully Sticks never contain preservatives or additives, and they’re made from 100% grass-fed beef.
