Using these dental sticks is easy. Just give one stick to your dog, and let them chew on it. Chewing helps clean their teeth and freshen their breath. Keep in mind that these are treats, so don't overfeed your dog. Store the sticks in a cool, dry place to maintain their freshness. If your dog has any dental problems or special dietary needs, it's a good idea to consult your vet before giving them these sticks.
