Cooked, plain, lean ground beef is generally safe for dogs in moderation, as it is a good source of protein. However, raw ground beef carries risks of bacterial contamination, which can cause gastrointestinal upset or more severe illness. High-fat ground beef, even when cooked, can lead to pancreatitis or digestive issues, so it's best to choose lean options and serve in small quantities.
