Xylitol is highly toxic to dogs because it causes a rapid release of insulin in their bodies, leading to hypoglycemia (low blood sugar). This can occur within 10 to 60 minutes of consumption and can be life-threatening. Symptoms of xylitol poisoning in dogs include:

In severe cases, xylitol can cause liver failure in dogs.

Regarding cats, they are generally less interested in sweet-tasting food, and there is less evidence of xylitol being toxic to them. However, due to the lack of research, it's advised to keep xylitol-containing products away from cats as well.

If your dog eats something with xylitol, it's crucial to act quickly:

1. Identify the Product and Amount: Determine how much xylitol the dog ingested and identify the product consumed.
2. Contact a Veterinarian Immediately: Time is critical. If it's during regular veterinary hours, call your veterinarian. After hours, contact an emergency veterinary clinic or a pet poison helpline.
3. Do Not Induce Vomiting Unless Instructed: Inducing vomiting without professional guidance can be dangerous. Follow the veterinarian's instructions.
4. Bring the Product Package: If possible, bring the package of the product containing xylitol with you to the vet. This can help them determine the amount of xylitol ingested.
5. Follow Veterinary Advice: The vet may induce vomiting, administer activated charcoal to absorb the xylitol, provide IV fluids, monitor blood sugar levels, and provide supportive care as needed.

Prevention is key. Keep all xylitol-containing products out of the reach of pets and inform everyone in your household about the dangers of xylitol to dogs.
