I think the important question here is “what’s dangerous for my pet to eat”, regardless if it’s a plant, a plant-based product, or any other thing.

Adding stuff like plain old “sugar” would be useful.

Also, aren’t grapes bad for dogs? By searching “grape” there are many results that, without something like a photo or a link to Wikipedia, makes it hard to know if that’s the thing I’m looking for. I don’t know the botanical family of a grape.
