Golden retrievers typically weigh between 55-75 pounds. All dog food brands should provide a guide as to how much food your dog should be given based on their weight. However, if you're unable to find a guide them the National Research Council of the National Academies recommends you feed them between 989-1,272 calories every day if they're not overly active. If they are a working dog that is up and about at all times, then between 1,353-1,740 calories would be better.
