If you own a dog who loves peanut butter you may want to read the label to look for an sugar substitute called Xylitol.
Xylitol is a sugar substitute that is naturally occurring. Xylitol is extracted from either corn cobs or birch bark. The Xylitol.org site lists the dental benefits, health and nutritional benefits of using Xylitol.While xylitol offers many health benefits to humans, it can be deadly to dogs and should not be fed to any pets.
Decide for yourselves on whether Xylitol is a benefit to humans or if you prefer to have more simpler ingredients in food you consume. If you do choose to use a brand with the Xylitol ingredient, do not feed that brand to pets since it can be toxic.
