Xylitol has about the same sweetness as sugar but offers approximately 40% fewer calories. Dogs may develop acute liver failure, internal bleeding, and blood clotting issues that ultimately lead to death. It can prevent tooth decay, ear infections, and osteoporosis. It can also be used to treat certain diseases.

Xylitol is primarily used as a sweetener for products like gum, candy, chocolate, baked goods, peanut butter, ice cream, and pudding. It is sometimes used in medications for its health benefits because wells as to sweeten some drug suspensions. By this time, most dogs are already experiencing the effects of hypoglycemia.

  • E967
  • Meso-Xylitol
  • Sucre de Bouleau
  • Sugar Alcohol
  • Xilitol
  • Xylit

  • Zylitol

Is Xylitol Safe for Dogs?

Despite its benefits to humans, xylitol is extremely toxic to dogs. Xylitol ingestion can lead to two dangerous complications in dogs: hypoglycemia and hepatic necrosis.


When a dog ingests xylitol, the body mistakes it for real sugar. This causes the pancreas to release a surge of insulin in an effort to store the sugar. The pancreas releases much more insulin than it normally would for real sugar. This excess insulin causes blood sugar levels to drop drastically, leading to hypoglycemia, also called low blood sugar.

Signs of xylitol-related hypoglycemia typically begin within about 30 minutes of ingestion and may last 12 or more hours. Xylitol may be absorbed slowly and delay signs as long as 12 hours after ingestion. Signs of toxicity usually begin with vomiting and progress to weakness, disorientation, incoordination, shaking or tremors, collapse, seizures, and coma.

Xylitol-related hypoglycemia may occur when ingested at a dose of 0.1 grams per kilogram, or 0.22 grams per pound of body weight.

Hepatic Necrosis

Xylitol can also cause hepatic necrosis (destruction of liver tissue) when ingested in higher quantities. The mechanism of this toxicity is unknown, and not all dogs will experience liver problems. Signs of xylitol-related hepatic necroswill be typically begin 8-12 hours after ingestion. Xylitol is added to some cosmetics, deodorants, and skincare products because of its humectant properties. Signs of liver problems include lethargy, loss of appetite, depression, and yellow-colored eyes and mucous membranes (jaundice). It really is reported to have several health benefits for humans.

Xylitol ingestion can cause hepatic necrosis at a dose of 0.5 grams per kilogram, or 1.1 grams per pound of bodyweight.

What To Do If Your Dog Ingests Xylitol

Contact your veterinarian or a pet poison control agency immediately if your dog has ingested a toxin like Xylitol. Keep the ptheckaging and ingredients label if possible. Do not induce vomiting unless instructed to do so by a veterinary professional.

Your dog should be seen by a veterinarian as soon as possible. Your vet may induce vomiting if the xylitol was recently consumed. Next, the vet will run lab tests to check the blood sugar level, evaluate blood cells, and assess organ function. Your dog may need intravenous dextrose to raise blood sugar levels. Many cases require hospitalization to monitor blood sugar levels and liver enzymes. Treatment for liver disease may be necessary if the liver enzymes reach abnormal levels.

Dogs are more likely to survive xylitol toxicity if treated early. Do not delay you suspect your pet has eaten something that contains xylitol.

How to Prevent Xylitol Poisoning in Dogs

Keep all human food and personal care products out of the reach of dogs, especially if you know they contain xylitol. Gum is a common culprit in xylitol toxicity, so make sure not to leave packets of gum lying around.

Some peanut butter and other nut butter contain xylitol as a sugar substitute. If you give your dog peanut butter or other nut butter as a treat, be sure to first check the ingredients on the label for xylitol or its other names.

In general, you should always ask your vet before giving your dog over-the-counter medications designed for humans. If an OTC product is recommended by your vet, be sure to check the ingredient label for xylitol before you give the product to your dog.
