These hard chews keep teeth clean and provide hours of chewing fun indoors or outside. Made from coffee wood, they're naturally odor-free. The chews also do not splinter into sharp fragments, instead, they break down into soft and small digestible chunks which prevent dental damage (If you notice the chew breaking down, do not be alarmed!) This is the perfect boredom buster for all dogs, especially those who are heavy chewers!! Coffee wood dog chew has many benefits such as: . Perfect stress relief . Zero calories . Vegan . Long lasting & extra tough . High quality . Natural . Dental health . Sustainable
