Halloween is three days away. This is the post I would rather you read now than need later.

Xylitol Is the Most Dangerous Thing in the Bowl
Xylitol is a sugar alcohol used in sugar-free gum, sugar-free candy, some peanut butters, some baked goods, and even some toothpastes. It is also called birch sugar on labels, so read the ingredients rather than the front of the package.
In dogs, xylitol causes a rapid insulin release, which drops blood sugar hard and fast, and in higher doses it causes liver damage. The dose that matters is small. A couple of pieces of sugar-free gum can be enough to send a small dog into a crisis.
This is the one that kills dogs that people thought were fine an hour earlier. Symptoms can come on within 30 minutes.
Chocolate
Chocolate contains theobromine, which dogs metabolize far more slowly than we do. The danger is dose-dependent, and two things drive it: how dark the chocolate is and how big the dog is.
Baking chocolate and dark chocolate are the worst. Milk chocolate is less concentrated but still a real risk in quantity. White chocolate has very little theobromine, though the fat and sugar can still cause a stomach upset.
Also worth knowing: caffeine is in the same chemical family and has the same effect, so coffee, tea, and energy drinks are on the list too.
The Rest of the Bowl
Raisins and grapes can cause kidney failure, and the mechanism is not well understood, which means there is no safe amount to assume. Macadamia nuts cause weakness and tremors. Sugar-free anything is a xylitol question. Candy wrappers and lollipop sticks cause obstructions. And a dog who eats a large volume of candy at once can end up with pancreatitis from the fat.
What to Do
If you think your dog ate something on this list, call your vet or a pet poison hotline immediately. Do not wait for symptoms. With xylitol especially, the window where treatment is easy is short, and by the time a dog looks sick the situation is already serious.
Have your dog’s weight ready and, if you can, what they ate and roughly how much. That is what lets a vet make a real assessment instead of a guess.
Then tonight: candy in a closed cupboard, not a bowl on the coffee table, and a dog who cannot reach the trick-or-treat bag. 🎃
