The full answer

Oregano is a kitchen herb used in Italian and Greek cooking. A very small pinch of the culinary herb is generally considered low risk for dogs, though it offers them nothing they need.

Larger amounts can cause stomach upset. Oregano essential oil is highly concentrated and can be harmful if swallowed or licked, so it should be kept away from dogs. Some products sold as oregano, such as Cuban oregano, are different plants and may be toxic, so be sure what you have.

Oregano usually appears in pizza, pasta sauce and marinades that contain garlic, onion and salt, which are not suitable for dogs. Keep those away from your dog.
