Using these Greenies dog dental treats is easy. Just give one treat to your dog every day. It's best to give the treat after a meal, so it can work on cleaning your dog's teeth right away. Make sure to pick the right size pack based on how often your dog will be having the treats. For storage, keep them in a cool, dry place. If your dog has any special dietary needs or health issues, it's a good idea to check with your vet before starting them on these treats. Also, always keep fresh water available for your dog when they're enjoying their treat.
