BarknBig Beef Steer Sticks are made from 100% U.S. beef pizzles. Because they're not as hard as bully sticks, steer sticks are often preferred by less-aggressive chewers and older dogs who tend to 'steer' away from hard bully sticks. Steer sticks do a great job of massaging the gums and stimulating jaw muscles and they're just plain delicious!
