Most peanut butter is safe, but some can be deadly. Recently, some peanut butter manufacturers switched to using the sweetener xylitol. Xylitol is a sugar substitute often found in sugar-free products like chewing gum, toothpaste, breath mints, chewable vitamins and baked goods. It is safe for people, but toxic to dogs.
Xylitol consumption causes a rapid release of insulin in dogs, which results in an equally rapid and profound decrease in blood sugar levels, and can be life threatening if left untreated. This condition, scientifically known as hypoglycemia, can occur as quickly as 10-to-60 minutes after eating xylitol.
Xylitol poisoning is easy to avoid. All owners need to do is check the label of the peanut butter and any other product they plan on feeding to their dogs for xylitol, and keep xylitol products out of their dogs' reach. If you think your dog has eaten xylitol, contact your veterinarian immediately, and keep an eye out for symptoms of xylitol poisoning, such as weakness, collapse, staggering, lack of coordination, and seizures.
Don't keep your pup in suspense any longer. Yes, dogs can eat peanut butter as long as it is fed in moderation and does not contain xylitol, so get out that peanut butter jar and share the good news.
