Vinegar is a sharp, sour liquid made by fermenting alcohol into acetic acid, used in cooking, pickling, and dressings. It offers no meaningful nutritional benefit, and the acidity may irritate the mouth, esophagus, or stomach, especially if undiluted. Do not deliberately feed vinegar; if a small taste occurs, offer fresh water and monitor for vomiting or discomfort.
Common types include distilled white, apple cider, rice, malt, and balsamic vinegar, and cleaning vinegars are more concentrated. Contact your veterinarian if a larger amount is ingested or if a strong cleaning vinegar is involved.
