Can dogs eat
French Fries?
With caution
Not recommended. A single plain, unsalted fry is unlikely to hurt, but fries are greasy and salty, and the seasonings or dips can cause real problems.
What to watch out for
Potato itself is not toxic once it is cooked. The trouble with french fries is everything done to the potato: deep frying in oil makes them very high in fat, and they are usually heavily salted.
PetMD notes that the oil in fries can upset a dog's stomach or trigger pancreatitis, a painful inflammation of the pancreas, and that frequent fatty foods can lead to obesity. Fries are also high in sodium, and too much salt can cause excessive thirst and, in larger amounts, serious salt poisoning. Most fries carry seasonings such as garlic salt, and they are often served with ketchup or sauces that add sugar and more of the same.
Fries also add calories with little nutrition. Dogs that are small, overweight, or prone to pancreatitis are the ones to be most careful with.
Benefits
- Plain cooked potato supplies some carbohydrate energy, though fries add little of value
Risks
- High fat content can cause stomach upset and may trigger pancreatitis
- Salt can lead to thirst and, in large amounts, salt poisoning
- Garlic or onion seasoning is harmful to dogs
- Sauces and dips add sugar, salt and sometimes onion or garlic
- Empty calories that contribute to weight gain
What to give instead
It is best not to feed fries on purpose. If you want to share something potato-based, offer a small piece of plain boiled or baked potato with no salt, butter or seasoning instead.
PetMD says one or two plain fries probably won't warrant a vet visit, so a rare accident is generally not a concern for a healthy dog. Do not give seasoned, flavored or sauced fries, and avoid fries for dogs with a history of pancreatitis or on a prescription diet.

| Seasoned or salted fries | No | Salt and garlic or onion seasoning make these unsuitable. |
| Sweet potato fries | With caution | Plain cooked sweet potato is fine, but fried and salted fries share the same fat and salt concerns. |
| Boiled or baked plain potato | In moderation | A better way to share potato, with no salt, butter or toppings. |
If your dog already ate it
A few fries usually cause nothing more than a mild upset stomach. Watch for vomiting, diarrhea, belly pain, loss of appetite or unusual tiredness over the next day or two.
Call your vet if your dog ate a lot, ate seasoned fries or ones with onion or garlic, has a history of pancreatitis, or shows any of those signs. Heavy salt intake can cause extreme thirst, tremors or seizures, which is an emergency. For poison advice in the US, call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply). Do not try to make your dog vomit at home.

Can french fries cause pancreatitis in dogs?
Fatty foods can trigger pancreatitis in some dogs, and fries are high in fat. Dogs that have had it before should avoid them entirely.
Are fries with ketchup okay?
Ketchup adds sugar and salt and sometimes onion or garlic, so it makes fries worse, not better. See our page on ketchup.
