WooCooper chew sticks are made from the best materials that mother nature gives. Coffee wood, which is 20-25 years old, is an ideal source of raw materials for making dog chew sticks. Coffee wood is much harder than other woods, so our chew sticks have good elasticity and are significantly less likely to break. Since coffee wood is the only ingredient in WooCooper sticks, our products are 100% vegan and free of harmful additives. We manufacture various chew stick sizes to ensure all dogs of different sizes can use WooCooper chew sticks. In addition, we do not harm the environment during the production process because natural wood is a secondary product in the coffee production process. Indeed, no trees will be cut down because of our products
