Can Dogs Eat Skittles? What the Label Says

Skittles are small, colorful and easy to lose under a couch, which is how most dogs end up with them.

What is on the label

I pulled the ingredient list for Original candy from Open Food Facts (product code 0040000011606). Ingredients are listed from the most to the least by weight.

Sugar, corn syrup, hydrogenated palm kernel oil; less than 2% of: citric acid, tapioca dextrin, modified corn starch, natural and artificial flavors, colors (red 40 lake, titanium dioxide, red 40, yellow 5 lake, yellow 5, yellow 6 lake, yellow 6, blue 2 lake, blue 1, blue 1 lake), sodium citrate, carnauba wax.

Recipes change, and flavors and package sizes can differ, so read the bag you actually have before you rely on this list.

What matters for your dog

• Sugar. Plain sugar isn’t poisonous to dogs, but a pile of it can upset a stomach and adds calories a dog doesn’t need. Sugar and corn syrup are the first two ingredients.
• Xylitol check. Pet Poison Helpline says xylitol is a sweetener found in many products, not just gum, and that it can cause life-threatening low blood sugar and liver failure in dogs. Xylitol is not on this label.
• Nothing else from ASPCA’s list. I compared this label to ASPCA’s list of people foods to avoid and didn’t find onion, garlic, chives, chocolate, caffeine, xylitol, grapes, raisins or macadamia nuts.

About Skittles

The Original label lists sugar, corn syrup, hydrogenated palm kernel oil, citric acid, tapioca dextrin, modified corn starch, flavors, a set of artificial colors with titanium dioxide, sodium citrate and carnauba wax. There’s no chocolate, no caffeine, no xylitol, and no onion or garlic.

Confirming that is the most important thing to do with any candy. Pet Poison Helpline names xylitol as a sweetener that can cause life-threatening low blood sugar and liver failure in dogs, and it turns up in sugar-free candy. Regular Skittles list sugar and corn syrup instead. Sugar-free candy is a different product and needs its own label check.

What’s left is sugar and calories a dog doesn’t need, plus the chance of a stomach upset from a big pile. I checked the Original. Sour, Wild Berry, Gummies and other versions have different labels.

Questions people ask

Are Skittles poisonous to dogs?

Nothing on the Original label is on ASPCA’s foods-to-avoid list. They’re sugar and dye, not food for a dog, and a big amount can still upset a dog’s stomach.

What about sugar-free candy?

Check the label for xylitol. Pet Poison Helpline says it’s found in sugar-free gum, mints, candies and many other products, and can cause life-threatening low blood sugar and liver failure in dogs.

My dog ate a whole bag. What should I do?

Call your vet, tell them the bag size and your dog’s weight, and watch for vomiting and diarrhea. Check the bag to confirm it was regular Skittles and not a sugar-free candy.
