I think “an entire large onion” or “one chocolate bar” are surprisingly large amounts, because my default assumption when something is called poisonous is that any amount is dangerous.
An onion or a chocolate bar is not that much, unless your dog is tiny. And no, the dose makes the poison, that’s the basic principle of toxicology. Anything can kill you, you can die from even drinking too much water too quickly.
