Xylitol is a deadly artificial sweetener that must never be given to dogs under any circumstances. Xylitol causes a catastrophic and rapid blood sugar collapse within 30 minutes of ingestion, leading to severe hypoglycaemia, seizures, loss of consciousness, and death. Even tiny amounts are lethal, particularly in small dogs. Xylitol also causes acute liver failure through direct hepatic toxicity. Xylitol is hidden in numerous products including sugar-free sweets, chewing gum, baked goods, peanut butter, toothpaste, and some medications. Every dog owner must check ingredient labels on all products. If your dog has consumed xylitol, seek immediate emergency veterinary care as this is one of the most life-threatening toxins.
