Lay’s Classic has one of the shortest labels you’ll find, which makes it an easy one to look up.
What is on the label
I pulled the ingredient list for Classic from Open Food Facts (product code 0028400355605). Ingredients are listed from the most to the least by weight.
Potatoes, vegetable oil (canola, corn, soybean, 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 Lay’s Chips
The label lists potatoes, vegetable oil and salt. That’s the whole list. No onion powder, garlic powder, dairy, sugar or chocolate.
The thing to think about is salt and grease. ASPCA says excessive salt can cause increased thirst and urination and, depending on the amount, vomiting, diarrhea and tremors. A single chip is a tiny amount. A whole bag is not.
Flavored Lay’s, like Sour Cream and Onion or BBQ, have different and longer lists, and some include onion or garlic. This page covers the Classic only.
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 plain potato chips?
The Classic label has nothing from ASPCA’s foods-to-avoid list, but chips are salty and greasy. A dog that grabbed one is a small concern. A dog that ate a bag is a call to your vet.
Are Lay’s baked or kettle chips the same?
No. Different lines have different recipes, so read the bag. I only checked Classic.
Is salt really a problem for dogs?
It can be. ASPCA says excessive salt can cause vomiting, diarrhea, tremors, seizures and even death, depending on the amount. Small amounts are very different from large ones.
