Our Apex Dentist Explains why Xylitol is Good for Teeth, Bad for Dogs

, by

Now that Halloween’s in the rear-view mirror, you might be motivated to give your body a break from all that sugar by switching to low-calorie sweeteners. If so, xylitol is a great option, because it’s natural, tasty, and deadly to the bacteria on your teeth. In fact, xylitol is one of the few things that can truly kill cavity-causing bacteria, which is why dentists highly recommend it. However, it’s important to be aware that xylitol is also very dangerous to dogs, for reasons we will explain below.

What is Xylitol?

Xylitol is found naturally in fruit, vegetable fibers, hardwood trees, corncobs, and certain other plant species. It was first used as a sweetener in Finland during World War II, when sucrose was unavailable. Xylitol has become very popular in the last few decades due to the fact that it’s just as sweet as sucrose, but has far fewer calories. Additionally, xylitol causes very little insulin release in humans, making it an excellent alternative for people with diabetes, prediabetes, obesity, or other metabolic problems. However, this is unfortunately not the case when it comes to dogs and other animals.

Why Does Xylitol Harm Dogs?

In people, rats, horses, and rhesus monkeys, xylitol causes little to no increase in insulin release or blood sugar levels. However, in species like dogs, cats, cows, goats, rabbits, and baboons, xylitol causes a large insulin release and drop in blood sugar. For dogs, the insulin release from is so massive that it causes the blood sugar to drop dangerously low, resulting in weakness, trembling, seizures, collapse, and even death. At very high dosages, xylitol can cause massive liver necrosis in dogs, in which large numbers of liver cells die abruptly, killing the animal.

Xylitol is just as harmful to cats, but there is less cause for concern when it comes to them. This is because cats typically ignore xylitol-heavy foods like gum, cookies, cake, and peanut butter.

Foods Which Contain Xylitol

While we highly encourage patients to chew sugar-free gum that contains xylitol, we also don’t want any harm to come to family pets. Make sure that you check the following products carefully for xylitol:

  • Toothpaste
  • Mouthwash
  • Chewing gum
  • Peanut butter
  • Sugar-free candy
  • Sugar free breath mints
  • Fruit drinks
  • Jellies and jams
  • Cereals
  • Baked goods
  • Sugar-free puddings and Jello
  • Over-the-counter vitamin supplements

Be aware, too, that not all product labels clearly state whether or not they contain xylitol. If a label states only, “artificially sweetened,” presume that it contains xylitol to err on the safe side. Always keep xylitol-containing products high out of reach, and try to induce vomiting immediately if you think your dog has ingested any.
