Cool Ranch is ranch seasoning on a chip, and ranch usually means onion and garlic.
What is on the label
I pulled the ingredient list for Cool Ranch Flavored from Open Food Facts (product code 0028400070546). Ingredients are listed from the most to the least by weight.
Corn, vegetable oil (corn, canola, and/or sunflower oil), maltodextrin (made from corn), salt, tomato powder, corn starch, lactose, whey, skim milk, corn syrup solids, onion powder, sugar, garlic powder, monosodium glutamate, cheddar cheese (milk, cheese cultures, salt, enzymes), dextrose, malic acid, buttermilk, natural and artificial flavors, sodium acetate, artificial color (red 40, blue 1, yellow 5), sodium caseinate, spice, citric acid, disodium inosinate, and disodium guanylate. contains milk ingredients.
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
- Onion powder and garlic powder. ASPCA says onion, garlic and chives are Allium vegetables that can cause gastrointestinal irritation and red blood cell damage, which can lead to anemia. It says dogs are at risk depending on the amount they eat.
- Salt. ASPCA says excessive salt can cause increased thirst and urination and, depending on the amount, vomiting, diarrhea, tremors, seizures and even death. Size matters: the same snack is a bigger dose for a small dog.
- Dairy. ASPCA says pets don’t have much lactase, the enzyme that digests lactose, so milk-based foods can cause diarrhea or other stomach upset. Whey, cheese, buttermilk and milk powders on a label all count.
About Doritos Cool Ranch
The Cool Ranch label lists onion powder and garlic powder, and then a stack of milk ingredients: lactose, whey, skim milk, buttermilk, cheddar cheese and sodium caseinate. It’s also seasoned with monosodium glutamate and a few artificial colors.
Two separate things apply. ASPCA says Allium vegetables (onion and garlic) can cause red blood cell damage in dogs depending on the amount, and that milk-based foods can cause diarrhea or digestive upset because pets don’t have much lactase.
I’d treat this the same way as Nacho Cheese: not a treat, and a call to the vet if a dog ate a bunch. A single chip is a much smaller concern than a bag.
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
Is ranch seasoning bad for dogs?
Ranch flavors often lean on onion and garlic, and on this Doritos label both are listed. ASPCA says those can harm a dog’s red blood cells depending on the amount.
Is Cool Ranch worse than Nacho Cheese?
Both list onion powder and garlic powder. Cool Ranch has more milk ingredients in its seasoning, so it may be harder on a dog’s stomach. Neither is a snack for dogs.
What if my dog ate the whole bag?
Call your vet or a poison hotline. Tell them the bag size, when it happened, and your dog’s weight.
