Raw material quality: Our Rawhide is sourced from Latin America, and our suppliers only use free range, grass fed and pasture finished bulls. These bulls come from the colder parts of the continent, where they are less exposed to bugs and other parasites. Production quality: We only use certified and inspected suppliers that follow hygiene standards and environmental protection protocols. Oral health benefits: Rawhide is a great way to help maintain your dog's oral hygiene and health. It can prevent the buildup of plaque and tartar on the teeth, and help to stop the formation of cavities. Rawhide bones can help prevent periodontal disease and gingivitis, both of which can cause not only oral pain, inflammation and tooth decay, but can also lead to chronic and life threatening disease in the heart, liver, kidney and joints when bacteria spread from the mouth throughout the rest of the body. Contains no added colors, preservatives or flavors.
