Froot Loops are the brightly colored cereal that ends up on the floor around kids, and dogs follow the colors.
What is on the label
I pulled the ingredient list for Kellogg’s Froot Loops Cereal 10.1oz from USDA FoodData Central (branded foods) (product code 00038000198861). Ingredients are listed from the most to the least by weight.
Corn flour blend (whole grain yellow corn flour, degerminated yellow corn flour), sugar, wheat flour, whole grain oat flour, modified food starch, contains 2% or less of vegetable oil (hydrogenated coconut, soybean and/or cottonseed), oat fiber, maltodextrin, salt, soluble corn fiber, natural flavor, red 40, yellow 5, blue 1, yellow 6, BHT for freshness. Vitamins and Minerals: Vitamin C (ascorbic acid), reduced iron, niacinamide, vitamin B6 (pyridoxine hydrochloride), vitamin B2 (riboflavin), vitamin B1 (thiamin hydrochloride), folic acid, vitamin D3, vitamin B12.
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 it adds calories a dog doesn’t need. Sugar is the second ingredient 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 Froot Loops
The label lists a corn flour blend, sugar, wheat flour, oat flour and modified food starch, then oil, salt, flavor and four dyes (red 40, yellow 5, blue 1 and yellow 6), plus added vitamins. No chocolate, xylitol, onion, garlic or dairy.
Sugar is the second ingredient. The dyes are what make it look like candy, but I couldn’t find a vet source that flags them, so I won’t guess about them. The practical issue is sugar all at once: a dry handful is small, a bowl or a box is not.
I checked original Froot Loops. Other versions, like Froot Loops Marshmallows, have different labels.
If your dog already ate some
Write down what it was, how much, when, and your dog’s weight, and keep the package. Then call your vet, ASPCA Poison Control at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661.
Don’t wait for symptoms if the snack has chocolate, xylitol, or a lot of onion or garlic in it. And don’t try to make your dog vomit with salt or salt water. Pet Poison Helpline says that can cause salt poisoning.
Questions people ask
Can dogs eat Froot Loops?
The label lists nothing from ASPCA’s foods-to-avoid list. It’s a sugary cereal, not food for a dog, so treat it as a rare nibble at most.
Are the food dyes a problem?
I couldn’t find a vet source that flags them, so I can’t tell you either way. The more certain issue is the sugar, and a big pile of it can upset a dog’s stomach.
What about milk with the cereal?
ASPCA says pets don’t have much lactase, so milk can cause diarrhea or digestive upset. Dry cereal is different from a bowl with milk.
