Nuts ‘n More, Krush Nutrition, and P-28 Foods all make peanut butter and nut-based spreads containing the ingredient. Xylitol is found in all kinds of food and dental products and is harmful to pets. It is known to cause hypoglycemia and liver problems in dogs. If a pet eats too much of this peanut butter that contains xylitol, it has the potential to be fatal.
It is very important to check labels and look for keywords that can indicate that any particular food contains xylitol. The label may blatantly state that it contains xylitol, but it may also say “contains natural sweetener” or something to that effect. Chemically, xylitol is classified as a sugar alcohol, so looking for this phrase would be a good idea as well. Because xylitol and other sugar alcohols are not technically sugar, they might also be found in products labeled “sugar-free” or “no sugar added.”
Though it doesn’t seem likely that xylitol will become more mainstream in peanut butter brands, it is very likely that more food products will contain it as time goes on. Being vigilant and checking labels before giving any treats to your pet is highly recommended.
