AVOID — French fries are fried and salted, so we recommend not giving them to dogs.
Fries are high in fat and salt. One dropped fry is unlikely to cause serious harm, but they should not be given as food or a treat. Plain cooked potato is a different topic.
A single dropped fry is unlikely to cause serious harm; watch for stomach upset. Contact your veterinarian if your dog ate a large portion, or has had pancreatitis. If your dog vomits repeatedly, has a painful belly, is very thirsty or very quiet, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away.
This page covers fried, salted potato fries. Plain cooked potato has its own page and a different rating.
PetMD says French fries are high in fat and salt and should be avoided, and its potato article advises against fried preparations.
PetMD also notes that an occasional dropped fry is unlikely to cause serious harm. The problem is feeding them.
