Tostitos are what people eat with salsa and queso, so the chip and the dip get mixed up.
What is on the label
I pulled the ingredient list for Tostitos Original Restaurant Style Tortilla Chips from Open Food Facts (product code 0028400063999). Ingredients are listed from the most to the least by weight.
Corn, vegetable oil (corn, canola, and/or sunflower oil), and salt.
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
- 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.
- 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 Tostitos
The Original Restaurant Style label lists corn, vegetable oil and salt. No onion or garlic powder, dairy, or sugar. That makes the chip itself one of the plainer ones.
The dips are another story. Salsa is often made with onions and garlic, and queso is dairy. Onion and garlic are on ASPCA’s list of foods to avoid, and ASPCA says milk-based foods can cause digestive upset, so a chip that went through the salsa is not the same as a plain chip.
The usual salt rule still applies. ASPCA says excessive salt can cause increased thirst and urination and, depending on the amount, more serious signs. Other Tostitos flavors, like Scoops and the seasoned kinds, 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 Tostitos?
The plain Original chip lists only corn, oil and salt. It’s salty and not food a dog needs. The dips are what to worry about.
Is salsa bad for dogs?
Salsa often contains onion and garlic, which ASPCA says can damage a dog’s red blood cells depending on the amount. Check the label of any salsa before sharing.
What about queso?
Queso is dairy, and ASPCA says milk-based foods can cause diarrhea or digestive upset in pets. Some queso also has onion or garlic.
