Note that a dog would need to eat a surprisingly large amount of onions, garlic, or chocolate in order to get sick.
which means that a 45-pound dog would only have to eat one medium-to-large onion to experience dangerous toxicity levels. Since most dogs would happily devour a bag of unattended onion rings or an onion casserole given the opportunity, this is a serious concern.
However, some dogs are more sensitive to garlic toxicity than others, and consumption of a toxic dose spread out over a few days could also cause problems.
consuming even one chocolate bar can have serious consequences, especially for small dogs.
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.
Your statement contradicts your quotes.
So, no surprisingly large amounts at all here.
