Most peanut butters are free of the sweetener, but its use as a low-calorie alternative to sugar is increasing, which means dog owners need to be vigilant when it comes to what their pets are eating. Peanut butter brands that contain xylitol include Go Nuts, Co., Krush Nutrition, Nuts 'N More and P28 Foods.
Symptoms of xylitol poisoning in dogs include vomiting, muscle weakness, difficulty walking and tremors - and they usually begin within 15-30 minutes of consumption. Anyone who suspects their dog may have accidentally eaten something containing xylitol should contact a veterinarian or call the Pet Poison Helpline.
