Did you know: Xylitol is deadly to dogs?

Xylitol is extremely toxic to dogs. Even small amounts of xylitol can cause hypoglycemia (low blood sugar), seizures, liver failure or even death in dogs.

Why is xylitol toxic to dogs?

In both humans and dogs, the level of blood sugar is controlled by the release of insulin from the pancreas. Xylitol does not stimulate the release of insulin from the pancreas in humans. However, when non-primate species like dogs eat something containing xylitol, the xylitol is quickly absorbed into the bloodstream, resulting in a potent release of insulin from the pancreas.  This rapid release of insulin causes a rapid and profound decrease in the level of blood sugar (hypoglycemia), an effect that occurs within 10-60 minutes of eating the xylitol. Untreated, this hypoglycemia can be life-threatening.

How much xylitol is poisonous to a dog?

The dose of xylitol that can cause hypoglycemia in the dog has been reported between 50 milligrams (mg) of xylitol per pound of body weight (100 mg per kg). The higher the dose ingested, the more the risk of liver failure. The most common source of xylitol poisoning that Pet Poison Helpline* gets calls about comes from sugar-free gum. Some brands of gum contain fairly small amounts of xylitol, and it would take up to 9 pieces of gum to result in severe hypoglycemia in a 45 pound (20 kg) dog, while 45 pieces would need to be ingested to result in liver failure. With other common brands of gum which contain 1 g/piece of gum, only 2 pieces would result in severe hypoglycemia, while 10 pieces can result in liver failure. As there is a large range of xylitol in each different brand and flavor of gum, it is important to identify whether a toxic amount has been ingested.

What should I do if my dog eats something containing xylitol?

Do not induce vomiting or give anything orally to your dog unless specifically directed to do so by your veterinarian. It is important to get treatment for your dog as quickly as possible.  As some dogs may already be hypoglycemic, inducing vomiting can make them worse!

What are the symptoms of xylitol poisoning?

Symptoms of xylitol poisoning develop rapidly, usually within 15-30 minutes of consumption. Signs of hypoglycemia may include any or all of the following:

  • Vomiting
  • Weakness
  • Lack of coordination or difficulty walking or standing
  • Depression or lethargy
  • Tremors
  • Seizures
  • Coma

In severe cases, the dog may develop seizures or liver failure. Dogs that develop liver failure from xylitol poisoning often show signs of hypoglycemia.
