Mighty Paw Naturals Bully Sticks Mighty Paw’s All-Natural Bully Sticks are sourced from grass-fed, free-range beef in Columbia and are hand-inspected and packaged in our HQ here in Rochester, NY. The odor-free bully sticks are made with only one single ingredient - beef pizzle - and don’t contain any added flavors! That makes them fully digestible, protein-rich, grain-free, gluten-free, chemical-free, preservative-free, mess-free, smell-free, and - most importantly - guilt-free! It also makes them a healthy, boredom busting alternative to bleached rawhide chews. They’re perfect for dogs with sensitive stomachs and chicken, lamb, pork, fish and grain allergies.
