Xylitol, a common sugar substitute known as a sugar alcohol, is frequently used in sugar-free chewing gums, mouthwashes, and other products. Recently, it has also been found in certain high-protein nut butter spreads—posing a serious risk to dogs.
Brands such as P28 peanut spread, Nuts ‘N More, and Krush Nutrition’s Nutty by Nature now include xylitol in their ingredients. While marketed as high-protein alternatives for humans, these spreads are often mistaken for traditional peanut butter—by both people and their pets. Because many dogs enjoy peanut butter as a treat, whether spread on a toy or spoon, the risk of accidental poisoning is real.
Why Xylitol is Dangerous for Dogs
Although xylitol is safe for human consumption, it is highly toxic to dogs. In canines, xylitol triggers a sudden release of insulin, as if the dog had consumed real sugar. This can lead to a rapid drop in blood sugar (hypoglycemia), and in more severe cases, may cause liver failure or seizures—both of which can be fatal without prompt medical treatment.
What You Can Do
- Always check ingredient labels before giving any human food to your pets.
- Do not assume that food safe for humans is also safe for animals.
- Avoid offering sugar-free foods to dogs, especially items labeled “low-carb” or “diet,” which may contain xylitol.
- Store sugar-free products safely out of your pet’s reach.
If you suspect your pet has ingested a product containing xylitol, contact a veterinarian immediately for emergency care.
