Xylitol is an artificial sweetener found in sugar-free gum, peanut butter, candies, and even some dental products. In dogs, it can cause a rapid drop in blood sugar, leading to seizures, liver failure, and even death.
What to Do: Xylitol poisoning progresses quickly. If your dog ingests xylitol, rush them to a vet immediately, as even small amounts can be life-threatening.
