It's actually very common especially among people who feed raw to fast a dog one day a week. Not at all abnormal and rarely does it cause vomiting or other problems. Some people going for healthy diets also fast themselves one day a week and then eat small frequent meals the rest. There are some breeds of small and toy dog who do have blood sugar issues though and need fed more often than standard medium-large breeds especially working breeds.
