TailVilleWhy
In dogs, xylitol triggers a massive insulin release, and blood sugar can crash within 10โ60 minutes. Larger amounts can destroy liver cells and lead to liver failure. Cats have been studied far less, so it's unclear whether they're as sensitive, which is exactly why it's safest to avoid it. It turns up in sugar-free gum, candy and mints, some peanut butters, toothpaste, chewable vitamins and diet baked goods, sometimes labeled as birch sugar.
How to give it / if eaten
If your pet ate even one piece of gum, call your vet, an emergency clinic or a poison control line immediately, even with no symptoms: low blood sugar can set in very fast. Bring the packaging with the ingredient list, note the time and amount, and don't induce vomiting at home unless a vet tells you to.
Watch for these signs
Within 30โ60 minutes: vomiting, weakness, wobbling, collapse, tremors or seizures. Yellowing of the gums or eyes, bruising or bleeding days later suggests liver damage.
FAQ
My dog ate one piece of xylitol gum. Is that dangerous?
A single piece can be enough to drop a small dog's blood sugar, and the amount varies by brand. Don't wait to see what happens: call your vet right away.
How can I tell if a product contains xylitol?
Look for xylitol or birch sugar on the ingredient list. Be extra careful with anything labeled sugar-free, such as gum, candy, peanut butter and toothpaste, and store it out of your pet's reach.
