Short answer
Stay calm — a small lick of plain olive oil is not toxic. Your immediate step is to clean up any remaining spill thoroughly to prevent your dog from consuming more. Next, offer your dog some fresh water, as the oil might cause mild thirst or a slightly upset stomach. Keep an eye on your dog for the next several hours for any signs of vomiting, diarrhea, or unusual lethargy, though these are unlikely from a tiny amount. Simply monitor at home and call your own vet only if you notice any concerning symptoms.
