Your dog deserves a treat that can not only deliver great taste, but also the highest quality nutrition available! Our beef lungs are made from USDA inspected Angus, born and raised in the USA. Just break them down to accommodate your dog's size and appetite. The perfect chew with light chewers with an affinity for a softer texture or crumble as a food topper! Each lung steak is about 1.5 oz and approximately 4-6 inches long, 3 inches wide and .5 inches thick.
