Our 6″ Thick Bully Sticks are all-natural and US local. They are great for smaller breeds of dogs. Although large dogs like them too, many larger dogs can eat a 6″ Thick Bully Stick fairly quick. As such, they are great snacks for large pooches; but are the perfect size for a smaller dog. Any Bully Stick will promote healthy teeth and gums because of the chewing action and saliva generation required to eat the stick.
